blood volume, the pumping efficiency of the heart, and the resistance of the peripheral vasculature.
Automatic electronic sphygmomanometers noninvasively measure and display a patient’s arterial blood
pressure. These devices can help overcome some of the problems associated with manual sphygmomanometry,
such as variations in user technique and hearing acuity and environmental concerns about mercury. Automatic
NIBP monitors can display blood pressure continuously or at preset intervals, saving time and allowing clinicians
to perform other tasks. In addition, most automatic blood pressure units display pulse rate and sound an alarm if
a patient’s blood pressure or pulse rate drops below or exceeds preset limits.
As one of the most frequently used diagnostic tests, it is critical to the
ongoing management of patients undergoing anesthesia or drug and other
therapies to determine the need for blood, a volume substitute (e.g., plasma
expander), or a change in medication. In addition, periodic measurements are
very important during operative procedures in which rapid blood pressure
fluctuations can occur. Although invasive techniques for measuring blood
pressure may provide greater accuracy and permit continuous measurement
during cardiac and respiratory cycles, noninvasive techniques are most often
used because of their low risk and simplicity, and they have proven to be
sufficiently accurate for many clinical applications.

Pulse oximetry
Pulse oximeters provide a noninvasive and continuous means of
monitoring the SpO2 of arterial blood, reducing the need for arterial puncture
and laboratory blood-gas analysis. The pulse oximeter uses two light-emitting
diodes (LEDs) that emit different wavelengths of light through a capillary bed
by means of a probe (usually placed over the adult patient’s fingertip, earlobe,
or toe or the neonate’s foot). A detector measures the amount of light absorbed
by oxyhemoglobin and deoxyhemoglobin. The transmitted light is converted
to electronic signals proportional to the absorbance values, from which SpO 2
values are calculated and displayed.

Temperature
Electronic thermometers electronically measure body temperature at oral,
rectal, and axillary sites; periodic temperature measurements are used as
primary diagnostic indicators. Healthcare facilities have largely substituted
these units for glass mercury thermometers, which can break easily and create a toxic hazard.

Principles of operation
Noninvasive blood pressure
When the left ventricle of the heart contracts, blood forced into the arteries creates a pressure increase, the peak
of which is called systolic pressure. The first number of a typical blood pressure reading represents this pressure.
The lowest point that the pressure reaches before the next ventricular contraction represents the diastolic
pressure, recorded as the second number in a blood pressure measurement. Most commonly, these pressure
values are recorded in millimeters of mercury (mm Hg)—for example, 120/80 mm Hg.
Automatic electronic blood pressure monitors use one of two measurement techniques: auscultatory or
oscillometric.
Auscultatory blood pressure monitors rely on the same principle as most manual sphygmomanometers: the

detection of Korotkoff sounds. When an inflated

air cuff subjects an artery to pressure that is
greater than the systolic pressure, the artery
closes and stops the flow of blood through it. As
the outside cuff pressure is gradually lowered, it
eventually falls below that of the systolic
pressure, and some blood does force its way
through the artery during the brief period when
the arterial blood pressure is higher than the cuff
pressure; however, the blood flow is not normal,
and the resulting turbulence produces Korotkoff
sounds. These sounds persist until the cuff
pressure falls below the diastolic pressure and Figure 1. Korotkoff sounds begin when cuff pressure falls below systolic
blood flow returns to normal. Thus, the pressure pressure and end when cuff pressure falls below diastolic pressure.
at which Korotkoff sounds first begin marks the
systolic pressure, while the pressure at which they disappear reflects the diastolic pressure (see Figure 1); a
microphone positioned against the compressed artery detects the Korotkoff sounds, enabling the user to directly
determine both systolic and diastolic values. Mean arterial pressure (MAP), the mean value exerted by flowing
blood over the cardiac cycle, is calculated from these values and displayed.
Conversely, in the oscillometric technique of determining blood pressure, when the pressure in the cuff falls, a
pressure transducer located in the monitor detects air-pressure fluctuations in the cuff instead of the Korotkoff
sounds. These pressure fluctuations are due to arterial volume changes that occur because of the pulsatile flow of
blood. The pressure at which the oscillations peak corresponds to the MAP. From the increasing and decreasing
magnitude of these oscillations, the device uses algorithms to calculate the systolic and diastolic pressures.
Most blood pressure monitors calculate pulse (heart) rate at each blood pressure reading, and most display
systolic, diastolic, and MAPs as well. While some units’ alarm systems can be set for all four parameters
simultaneously, others monitor only one at a time or monitor one parameter only. Some units also include
arrhythmia detectors to alert users regarding the presence of an irregular heart rate. Many units can also measure
other physiologic conditions, such as temperature and oxygen saturation.
Options available from most manufacturers include cuffs of different sizes and a printer. Different-size cuffs
are necessary to allow the monitoring of many types of patients, including neonates and the very obese; wrist and
thigh cuffs are also available.

Pulse oximetry
Pulse oximeters use the principle of differential light absorption to determine the percentage of SpO₂ of
hemoglobin in arterial blood. Pulse oximetry sensors are applied to an area of the body, such as a finger, a toe, or
an ear. Two wavelengths of light (e.g., 660 nm [red] and 930 nm [infrared]) are transmitted through the skin into
the tissue by the sensor's LEDs and are differentially absorbed by the blood's oxyhemoglobin, which is red and
absorbs infrared light, and deoxyhemoglobin, which is blue and absorbs red light. The sensor’s photodetector
(which is on the opposite side of the LED) converts the transmitted light into electrical signals proportional to the
absorbance. The signal is then processed by the unit’s microprocessor, which derives a saturation reading and, if
the reading is outside the alarm limits, sounds an alarm.
Each pulse of arterial blood causes cyclic variations in the path length of the transmitted light through the
sensor site, varying the amount of light absorbed by the arterial blood. A portion of the light passing through the
sensor site is absorbed by venous blood, tissue, or bone components; however, this absorption is relatively
constant over short periods of time and the microprocessor can isolate this constant when performing
calculations. Most current units will have advanced signal-processing techniques that can read through motion

artifact and/or conditions of low perfusion. Also, to reduce small variations in displayed oxygen saturation values
and to counter any false values from artifactual waveforms, pulse oximeters use algorithms to average data over a
few seconds.
Sensors used on the finger, toe, foot, nose, and ear are transmittance
sensors. However, it is possible to use flat reflectance sensors, which
measure the intensity of light reflected (backscattered) from the skin (e.g.,
forehead sensors). Depending on the application, one sensor type may be
preferred (e.g., reflectance forehead sensors may be advantageous in the
operating room for trauma patients who have damaged or poorly perfused
transmittance sensor sites). Reflectance sensors may respond more quickly
to desaturation than transmittance sensors, especially in patients having
poor peripheral perfusion.
Both disposable and reusable sensors are available for many oximeters.
Reusable sensors include spring clip-style probes, which can be applied to a
measurement site (e.g., finger, ear). Disposable sensors, for single-patient
use, are usually adhesive-style sensors that can be applied to a
measurement site (e.g., finger, toe, foot). Sensors are available in sizes
suitable for adults, children, and neonates. It is important to use the sensor
type designed for the patient being monitored.

Temperature
Electronic thermometers consist of a temperature-sensing probe and a digital display. A thermistor or
thermocouple sensor in the probe produces electrical signals that vary with changes in temperature; these signals
are converted into a temperature display. Thermistors are composed of metal (e.g., manganese, nickel, cobalt,
iron, zinc) oxides sintered into wires or fused into rods or beads. The resistance of these metal oxides decreases as
the temperature increases and vice versa; probe resistance can thus be converted into a temperature reading.
Thermistors have rapid response times, are small in size, and highly sensitive to temperature changes.
Thermocouple sensors consist of two dissimilar metals (such as copper and constantan, a copper-nickel alloy)
joined together at a junction. The thermocouple generates a voltage that is proportional to the difference in
temperature between the thermocouple junction (sensor) and the junction formed at the connection to the
monitor. The monitor compensates for the temperature of this second junction so that it can display the
temperature of the sensor, which is placed in or on the patient. Thermocouple probes are accurate, small, and
very stable and respond rapidly to temperature changes.
The overall response time of different thermometers varies because of differences in circuitry and, to a lesser
extent, differences in probe and probe cover designs. The probe tip, which is usually cooler than the patient’s
body, causes an initial temperature drop and can take from a few seconds to a minute to equilibrate and yield a
display, depending on the operational mode: the steady-state mode displays an actual final temperature after the
sensor equilibrates, whereas the predictive mode measures the initial rate of temperature change and displays a
predicted final temperature extrapolated from a standard temperature-versus-time curve. Predictive
thermometry is faster than steady-state thermometry, but its accuracy is more difficult to verify. Predictive
thermometer probes also require quick and accurate placement because they begin to calculate temperature upon
initial contact with body tissue.
Most units offer both operational modes, switching between them either manually (by using a push button or
switch or by unplugging and replugging the probe) or automatically. Automatic-switching units move from
predictive to steady-state modes in response to ambient temperatures of 35°C (95°F) or higher; otherwise,
predictive circuitry would calculate the initial rate of temperature change based on the high ambient temperature,
producing erroneously high readings.

Since probes differ in design, some are more comfortable for patients than others, and some can be held in
position more easily than others. Oral, rectal, and axillary probes are constructed of metal, rigid or pliable plastic,
or rigid plastic with a metal tip. The same type of probe is typically used for both oral and axillary sites; some
manufacturers provide probes designated for rectal use only. When one probe is provided for all uses, oral and
rectal probe covers may differ in design. Removable probe covers prevent the probe assembly from directly
contacting the patient and becoming contaminated; a new probe cover is used for each patient to prevent cross-
contamination. The probe is inserted into the cover and is removed by pressing an eject button or by pulling the
probe out by hand. Covers can be rigid or pliable opaque plastic or soft, clear polyethylene.
Many thermometers provide electronic features such as a final-temperature indicator (beep), a switch for
Celsius or Fahrenheit measurements, audible and visual indicators/alarms, and automatic calibration.

Alarms
Units will alarm when alarm limits are violated. Alarms are visual and audible; most audible alarms can be
manually temporarily silenced. Visual alarms can include systolic pressure, diastolic pressure, MAP, pulse,
arrhythmia detection, temperature, low perfusion, low signal strength, low battery, probe status, silenced audible
alarm, and system status.

Reported problems
Noninvasive blood pressure
Both invasive and noninvasive methods have certain limitations that clinicians should keep in mind when
measuring blood pressure. Studies have shown that automatic electronic blood pressure monitors may give
readings that are substantially different from those taken by a direct arterial catheter. The significance of these
findings, however, is controversial, because similar differences have also been detected between meticulous
manual sphygmomanometry and arterial catheter measurements. Additional research has even determined that
most NIBP monitors are capable of generating information nearly identical to that of currently used invasive
monitors. Also, direct arterial measurements do not necessarily represent the true arterial pressure, although
many clinicians use them as a standard reference.
A distinct drawback to automatic electronic sphygmomanometry is the inability to effectively monitor patients
with certain conditions (e.g., tremors, convulsions, abnormal heart rhythms, or who are connected to heart-lung
bypass units). Readings from patients with extremely low blood pressure, such as those in shock, are difficult to
obtain with auscultatory monitors. Conditions that might preclude use of a device employing a finger cuff
include emaciation, hypovolemia, low central venous pressure, low cardiac output, low peripheral temperature,
and vasoconstriction.
Other problems associated with automatic sphygmomanometers, such as ulnar nerve palsy and venous
hemostasis, can also be caused by manual sphygmomanometers and depend on factors such as cuff placement
and size, pressure, and duration of inflation. (One researcher suggests that to keep pressure from damaging the
ulnar nerve, users place the air cuff as high as possible on the arm to minimize venous occlusion.) If possible, the
cuff should be placed on a limb that is at heart level to avoid the need to correct for differences in hydrostatic
pressure. Excessive patient movement or improper cuff placement can produce artifacts that result in inaccurate
readings. Using a cuff bladder that is too wide underestimates blood pressure, while too narrow a cuff bladder
overestimates blood pressure.
The variable nature of systolic, diastolic, and mean blood pressure values taken from NIBP monitors, whether
caused by mechanical or user error, reinforces the importance of considering the average of a few successive
readings rather than just one.

Pulse oximetry
Bright visible light (e.g., surgical lighting, bilirubin lights, fire alarm strobe lights during fire drills) and
infrared sources (e.g., radiant warmers) can interfere with pulse oximeter sensors because the sensors are
designed to measure weak light signals transmitted through skin and tissue. Manufacturers often suggest placing
an opaque material over the sensor. This will frequently eliminate such interference, but clinicians must remain
alert to potential problems. Reusable clip-style sensors are generally less susceptible to ambient light interference
than disposable sensors. Reusable sensors have a design that is more rugged and more impermeable to light.
ECRI Institute has received reports of burns resulting from the use of functionally incompatible sensors, even
though the sensors are physically compatible with the oximeter. To ensure compatibility, only sensors specified
by the manufacturer should be used. Should users decide to use alternate source pulse oximeter sensors, ECRI
Institute recommends obtaining written confirmation of compatibility from the alternate source supplier. This
confirmation should state that the sensors will provide adequate accuracy with your specific model of pulse
oximeter or physiologic monitor over the full range of clinically relevant saturation values (e.g., 70% to 100%
SpO2). Also, using alternate source sensors may void some warranties.
ECRI Institute has also received reports of potential interference between pulse oximetry and magnetic
resonance imaging (MRI) systems. Burns have been reported at the probe site during MRI procedures, probably
resulting from electrical currents in the probe’s cable induced by the RF magnetic field during imaging. In
addition, the MRI unit’s magnetic field can affect pulse oximeter circuitry and performance, while the pulse
oximeter’s electronics can produce artifacts on the MR image. The MR compatibility of a pulse oximeter should be
verified with the manufacturer before use in a particular MR environment. For more information on MR
compatibility, refer to the December 2001 issue of Health Devices, which contains a guidance article on the use of
equipment in the MR environment. For more information about MRI, see the Product Comparison titled Scanning
Systems, MRI .
Most pulse oximeters cannot detect carbon monoxide (CO) poisoning because they cannot distinguish
carboxyhemoglobin from oxyhemoglobin—the value obtained is generally the sum of the oxyhemoglobin and
carboxyhemoglobin saturations. In marked contrast to other forms of hypoxia, CO poisoning causes the blood
and skin to become a brighter red rather than the blue usually associated with lack of oxygen in the tissues;
patients may appear well oxygenated according to the usual visual clues, but they may still be deficient in
oxygen. Thus, when CO poisoning is suspected, as in smoke-inhalation victims, arterial blood gas analysis should
be performed using the arterial puncture technique and appropriate laboratory instruments, such as a co-
oximeter (see the Product Comparison titled Oximeters, In Vitro, Laboratory). Pulse oximeters also cannot
distinguish methemoglobin from oxyhemoglobin and do not measure CO 2 or pH, which are important in
pulmonary gas exchange and assessment of acid base status.
A number of other factors can affect pulse oximetry measurements. Intravenous dyes such as methylene blue,
indigo carmine, or indocyanine green can cause inaccurate readings. It is advisable to remove any polish or false
nails from the patient’s fingernails before applying the sensor because certain nail-polish colors and cover
materials can interfere with SpO2 measurements. Extreme forms of anemia (a low number of red blood cells or a
low amount of hemoglobin) and heavily pigmented skin can prevent sufficient light from penetrating through to
the photodetectors to obtain accurate results. Generally, bilirubin does not interfere significantly with pulse
oximetry (it has minimal absorption at pulse oximetry wavelengths) and may be insignificant even with bilirubin
concentrations greater than 10 mg/dL.
Movement of the sensor, clinical or otherwise, may be detected and displayed by the oximeter as artifact and
can cause inaccurate readings. The effects of interference caused by motion can be reduced, or even eliminated,
by digital signal processing and by averaging the displayed SpO 2 over several seconds. Displaying the arterial
plethysmographic waveform can allow the operator to visually assess signal quality and observe any motion
artifacts that might alter the unit’s accuracy. Also, some pulse oximeters may have a feature that specifically

 Monitors, Vital Signs; Sphygmomanometers, Electronic, Automatic

measures signal strength. Likewise, the perfusion index can assist the clinician in determining signal strength or
the applicability of a sensor site.
Conditions that affect pulse detection can limit the measurement capability of the oximeter. For example, if an
arterial pulse is not significantly stronger than the surrounding venous blood and tissue, the oximeter may not be
able to differentiate between nonpulsatile and pulsatile absorbances. Low pulse signals result from decreased
circulation to the measurement area (low perfusion), the causes of which include hypothermia, peripheral
vascular disease, hypotension, vasoconstrictive drug therapy, and low cardiac output. To compensate, a sensor
can be applied to the bridge of the nose, spanning the nasal septum, or on the forehead, which may provide a
stronger signal since the body automatically protects circulation to the brain under stressful conditions as
opposed to protecting peripheral areas (e.g., finger, toe). Digital signal processing techniques offered by several
suppliers allow pulse oximeters to accurately read through low-perfusion conditions, and an alarm will sound
should a low-perfusion or no-pulse condition be detected.
Other factors that may rule out pulse oximetry are hemoglobin levels <5 mg/dL and the use of tourniquets,
blood pressure cuffs, or intravenous infusion (which can cause vasoconstriction) in the same extremity as the
oximeter.

Temperature
Hospital-acquired infections have been traced to the rectal-probe handles of several two-piece electronic
thermometers. The investigators suggest that soiling above the thermometer probe cover is likely when these
thermometers are used for rectal temperatures, especially in incontinent patients or those unable to cooperate
during the procedure (Livornese et al. 1992).
Probe cover damage has been reported when patients bite down on the cover during oral measurements.
Other incidences of splitting and leaking have occurred during regular use. Covers should detach easily, reducing
the amount of direct user contact with the actual probe, and unused probe covers should be kept in an easily
accessible carrying box.

Purchase considerations
ECRI Institute recommendations
Included in the accompanying comparison chart are ECRI Institute’s recommendations for minimum
performance requirements for electronic, automatic sphygmomanometers.
NIBP measurements are obtained using either the oscillometric or auscultatory method. The inflation pressure
should be adjustable or automatically set based on a previous or current pressure reading or individual patient
requirements; however, typical ranges include 150 to 260 mm Hg for an adult and 85 to 140 mm Hg for a neonate.
The unit should be able to measure systolic pressures as high as 250 mm Hg. Cuff inflation should be no greater
than 80 mm Hg/sec to minimize patient reactions. Cuff deflation should be 2 to 3 mm Hg/sec, depending on the
pulse rate. The timing between automatic blood pressure measurement cycles should be selectable from at least
five values over a range of 1 to 60 minutes. The sphygmomanometer should automatically deflate if the cuff
pressure reaches 300 mm Hg for an adult and 150 mm Hg for a neonate. Some units may also take SpO2 and
temperature readings.
The unit should display systolic and diastolic pressures and pulse rate. MAP and other physiologic parameters
(e.g., temperature, pulse oximetry) are optional and should be selected based on clinician and patient
demographic requirements.
The unit should alert the operator, either visually or audibly, if it is unable to take an accurate measurement
and should give the reason for the error. It should not be possible to set an alarm’s volume low enough to silence
it or to set alarm limits outside the specified measurement range of the unit.

Monitors, Vital Signs; Sphygmomanometers, Electronic, Automatic

Cuffs should be available in one or more of the following sizes: neonatal, pediatric, adult, large adult, and
thigh.
The unit can operate on both line and battery power. For battery-powered units, any commonly available
battery is acceptable. Rechargeable batteries are preferred because this reduces the costs of replacing and
disposing of batteries. The unit should be capable of operating on battery power for at least one hour and have a
low-battery indicator.

Other considerations
Vital signs monitors range in price from $750 to $10,000. More expensive models have additional monitoring
capabilities, such as oxygen saturation and temperature. The degree of sophistication chosen often depends on
where the unit will be used and the types of monitors currently used in that location. Advanced units can be
networked to a central monitor to facilitate data transfer.
Costs associated with the following should be considered:
 Reusable probes/sensors and their sterilization
 Disposable probes/sensors, if used
 Other disposables (e.g., probe covers for reusable probes)
 Replacement batteries
Suppliers frequently offer adjunctive equipment, which can include monitor stands and pressure cuffs of
assorted sizes. The value of this equipment, along with that of the warranty, guarantee, and possible discount,
should be assessed before making a purchase.

Environmental considerations
As a result of increasing concerns over the environment and the conservation of resources, many
manufacturers have adopted green shipping and production methods, as well as features that improve the energy
efficiency of their products or make them more recyclable. In addition, healthcare facilities and device
manufacturers have begun to adopt green initiatives that promote building designs and work practices that
reduce waste and encourage the use of recycled materials.
Some models offer energy-saving features, such as automatic shutoff or standby or hibernation mode.
Additionally, many countries have organizations that mark products as having reduced environmental impact.
For example, hospitals should look for manufacturers that offer models in which the components are designed to
be compliant with the U.K. standard Restriction of the Use of Certain Hazardous Substances (RoHS). RoHS limits
the use of cadmium, hexavalent chromium, lead, mercury, and other flame retardants in electrical and electronic
equipment. More information is available online at http://www.rohs.gov.uk.

Stage of development
The increased density of today’s integrated circuits has decreased the size of patient monitors and has allowed
the incorporation of many parameters into one module. Smaller monitors not only facilitate portability, but also
enable continuous monitoring of a patient, even during transport.
The widespread use of microprocessors and faster electronics has allowed such capabilities as automatic
calculation of hemodynamic parameters, expanded graphic and tabular trends, and the ability to integrate
bedside monitors with computer systems and other monitoring equipment.
Other recent developments include electronic charting systems, which automatically record physiologic data
from the monitor on the chart at preselected intervals, allow entry of nurse and physician notes, and can be
networked into critical care unit data management systems.

Note: The data in the charts derive from suppliers’ specifications and have not been verified through
independent testing by ECRI Institute or any other agency. Because test methods vary, different products’
specifications are not always comparable. Moreover, products and specifications are subject to frequent changes.
ECRI Institute is not responsible for the quality or validity of the information presented or for any adverse
consequences of acting on such information.
When reading the charts, keep in mind that, unless otherwise noted, the list price does not reflect supplier
discounts. And although we try to indicate which features and characteristics are standard and which are not,
some may be optional, at additional cost.
For those models whose prices were supplied to us in currencies other than U.S. dollars, we have also listed the
conversion to U.S. dollars to facilitate comparison among models. However, keep in mind that exchange rates change
often.

Policy Statement
The Healthcare Product Comparison System (HPCS) is published by ECRI Institute, a nonprofit organization.
HPCS provides comprehensive information to help healthcare professionals select and purchase diagnostic and
therapeutic capital equipment more effectively in support of improved patient care.
The information in Product Comparisons comes from a number of sources: medical and biomedical
engineering literature, correspondence and discussion with manufacturers and distributors, specifications from
product literature, and ECRI Institute’s Problem Reporting System. While these data are reviewed by qualified
health professionals, they have not been tested by ECRI Institute’s clinical and engineering personnel and are
largely unconfirmed. The Healthcare Product Comparison System and ECRI Institute are not responsible for the
quality or validity of information derived from outside sources or for any adverse consequences of acting on such
information.
The appearance or listing of any item, or the use of a photograph thereof, in the Healthcare Product Comparison
System does not constitute the endorsement or approval of the product’s quality, performance, or value, or of
claims made for it by the manufacturer. The information and photographs published in Product Comparisons
appear at no charge to manufacturers.
Many of the words or model descriptions appearing in the Healthcare Product Comparison System are
proprietary names (e.g., trademarks), even though no reference to this fact may be made. The appearance of any
name without designation as proprietary should not be regarded as a representation that is not the subject of
proprietary rights.
ECRI Institute respects and is impartial to all ethical medical device companies and practices. The Healthcare
Product Comparison System accepts no advertising and has no obligations to any commercial interests. ECRI
Institute and its employees accept no royalties, gifts, finder’s fees, or commissions from the medical device
industry, nor do they own stock in medical device companies. Employees engage in no private consulting work
for the medical device industry.

About ECRI Institute

in healthcare to uncover the best approaches to improving patient care. As pioneers in this science for more than
40 years, ECRI Institute marries experience and independence with the objectivity of evidence-based research.
More than 5,000 healthcare organizations worldwide rely on ECRI Institute’s expertise in patient safety
improvement, risk and quality management, healthcare processes, devices, procedures, and drug technology.

Health Organization and an Evidence-based Practice Center by the U.S. Agency for Healthcare Research and
Quality. For more information, visit http://www.ecri.org.
