Blood Pressure

Blood pressure is measured using a sphygmomanometer, which includes an inflatable cuff and manometer. It is determined by the amount of blood the heart pumps and the resistance in the arteries. A reading has two numbers - systolic (top number measuring pressure when the heart beats) and diastolic (bottom number measuring pressure between beats). Normal blood pressure is 90/60 mmHg to 120/80 mmHg. To take a reading, the cuff is placed on the arm and inflated until the artery is collapsed. It is slowly released while listening with a stethoscope to determine the systolic and diastolic pressures.

Blood Pressure

Materials Needed:

SPHYGMOMANOMETER
1. Aneroid
Mercurial Blood Pressure

2. Digital
Sphygmomanometer

Stethoscope
A sphygmomanometer also known as a blood pressure monitor, or blood pressure gauge,

is a device used to measure blood pressure, composed of an inflatable cuff to collapse and then release
the artery under the cuff in a controlled manner,and a mercury or aneroid manometer to measure the
pressure.

Manual sphygmomanometers are used with a stethoscope when using the auscultatory technique.

Blood pressure is determined both by the amount of blood your heart pumps and the amount of
resistance to blood flow in your arteries.

The more blood your heart pumps and the narrower your arteries, the higher your blood pressure.
A blood pressure reading is given in millimeters of mercury (mm Hg).

It has two numbers: N - 90/60, 100/70, 110/80, 120/80,


130/90 prehypertension - 3 months

Hypertensive - 140/ 100, 150/100 - - DIZZINESS, LIGHTHEADEDNESS, N/V, HEADACHE

POSITION: THE HEAD SHOULD BE HIGHER THAN THE BODY - SITTING – FOWLERS – SEMI FOWLERS

PROVIDE A WELL VENTILATED

- systolic/ diastolic - S/D = 30 – 40

120/80 – standard / normal

120 - systolic – 160 - first sound loud and strong

80 – diastolic - weak sound of beat

Top number (systolic pressure). The first, or upper, number measures the pressure in your arteries
when your heart beats.

- The first/ loud movement and beat

Bottom number (diastolic pressure). The second, or lower, number measures the pressure in your
arteries between beats.

- Relax/ weak
Normal Range

Minimum 90/60 mmHg – 120/80 mmHg

Low reading – hypotension 80/50 mmHg

High reading – hypertension 140/100

Prehypertensive – 130/90

How to Take Blood Pressure

1. Place cuff on upper arm with arrows pointing to the location of the brachial artery.

2. Place stethoscope over the location of the artery.

3. Inflate cuff to about 160. ( If it does not inflate, check to make sure the valve is closed. )

4. Listen. Slowly release valve, the number on the gauge will drop.
5. The first “blurp” sound you hear is the systolic pressure.
6. Listen. You should hear the sound of a heartbeat, it may even get louder. When you stop hearing
the sound, note the number on the gauge. This is the diastolic pressure.
