What’s a normal level of arterial oxygen?
Determining your blood oxygen level is an important part of diagnosing a variety
of health conditions. There are different ways this can be done.
An arterial blood gas (ABG) test can measure the amount of oxygen and carbon
dioxide in a blood sample taken from your artery, typically in your wrist. Arteries
are blood vessels that carry oxygen-rich blood to the organs and tissues in your
body.
Because the blood sample comes from an artery, the results of an ABG test can
give your doctor an idea about the oxygen level of the blood that’s currently being
delivered to your body’s tissues. It can also let them know how effectively carbon
dioxide has been removed from your blood.
ABG test results
Values between 75 and100 mm Hg Trusted Source are considered normal for an
ABG test. When values fall below 75 mm Hg, you’re considered to have
hypoxemia.
Another value reported by the ABG test is oxygen saturation. This is a measure of
how much oxygen is being carried by hemoglobin on your red blood cells. Normal
values for oxygen saturation are between 95 and 100 percent. (Trusted source)
Pulse oximetry
You may also be familiar with pulse oximetry. This measures your blood oxygen
levels using a device that you clip onto your finger. It reports oxygen saturation as
a percentage. Pulse oximeters are generally less accurate than an ABG test.
For most people, a normal reading falls between 95 and 100 percent, although this
may be lower if you have a known lung condition or live at a high elevation.
If you’re otherwise healthy and receive a reading of 92 percent or less on an at-
home pulse oximeter, contact your doctor.
What are the symptoms of hypoxemia?
Someone with hypoxemia may experience the following symptoms:
shortness of breath
fast breathing
rapid heartbeat
coughing or wheezing
headache
feeling confused or disoriented
a blue coloration to the skin, lips, or fingernails
Hypoxemia is a serious condition. Seek immediate medical attention if you or
someone else is showing signs of hypoxemia.
What can cause hypoxemia?
There are many conditions that can cause hypoxemia. These include:
acute respiratory distress syndrome (ARDS)
anemia
asthma
a blood clot in the lung (pulmonary embolism)
a collapsed lung
congenital heart defects or disease
chronic obstructive pulmonary disease (COPD)
fluid in the lung (pulmonary edema)
high altitudes
interstitial lung disease
medications that lower breathing rate, like some narcotics and anesthetics
pneumonia
scarring in the lungs (pulmonary fibrosis)
sleep apnea
Hypoxemia can be caused in different ways. Let’s look at a couple of examples of
conditions that can lead to hypoxemia:
Chronic obstructive pulmonary disease (COPD) is a chronic condition where the
flow of air in the lungs is obstructed. With COPD, the destruction of the walls of
the alveoli and surrounding capillaries can lead to problems with gas exchange
which, in turn, can cause hypoxemia.
Anemia is a condition in which there aren’t enough red blood cells to effectively
carry oxygen. Because of this, a person with anemia may have low levels of
oxygen in their blood.
Additionally, hypoxemia can be a symptom of another condition like respiratory
failure.
Respiratory failure occurs when not enough oxygen passes from your lungs to your
blood. Therefore, low blood oxygen levels can be an indicator of respiratory
failure.
Emphysema
Emphysema is a condition that falls under the umbrella of COPD. It causes
harmful changes to the alveoli.
With emphysema, the walls of the alveoli become damaged, causing them to
become weak, floppy, and less elastic. Because of this, they can’t fill up with air
properly when you breathe in. This means that less oxygen is able to enter your
blood during gas exchange.
Over time, the alveoli can also be destroyed. When this happens, it reduces the
surface area of your lungs. This makes it harder to breathe and restricts how much
oxygen can reach your bloodstream.
The most common cause of emphysema is long-term exposure to harmful gases,
most often cigarette smoke. In fact, it’s estimated that 80 to 90 percent Trusted
Source of people with COPD smoke cigarettes.
Other potential causes are long-term exposure to secondhand smoke or air
pollution.
Hypoxemia in newborns
Hypoxemia can sometimes occur in newborns with congenital heart defects or
disease. In fact, measuring the levels of oxygen in the blood is used to screen
infants for congenital heart defects.
Preterm infants are also vulnerable to hypoxemia, particularly if they’ve been
placed on a mechanical ventilator.
Types of Hypoxemia
There are several different types of hypoxemia. These types are differentiated by
the way in which blood oxygen levels are lowered.
Ventilation/perfusion (V/Q) mismatch
This is the most commonTrusted Source type of hypoxemia. Ventilation refers to
the oxygen supply in the lungs, while perfusion refers to the blood supply to the
lungs.
Ventilation and perfusion are measured in a ratio called V/Q ratio. Normally,
there’s a small degree of mismatch in this ratio, but problems can occur if the
mismatch becomes too great.
There are two causes of ventilation-perfusion mismatch:
The lungs are getting enough oxygen, but there’s not enough blood flow (increased
V/Q ratio).
There’s blood flow to the lungs, but not enough oxygen (decreased V/Q ratio).
Several conditions can lead to a V/Q mismatch, including but not limited to:
COPD
asthma
interstitial lung disease
fluid in the lung (pulmonary edema)
a blood clot in the lung (pulmonary embolism)
Shunt
Normally, deoxygenated blood enters the right side of the heart, travels to the lungs
to receive oxygen, and then travels to the left side of the heart to be distributed to
the rest of the body.
With this type of hypoxemia, blood enters the left side of the heart without
becoming oxygenated in the lungs. This leads to oxygen-depleted blood traveling
to your body’s tissues.
Shunts can be caused by:
congenital heart defects or disease
a tangle of incorrectly formed blood vessels (arteriovenous malformations)
pneumonia
fluid in the lung (pulmonary edema)
acute respiratory distress syndrome (ARDS)
Diffusion impairment
As we discussed earlier, when oxygen enters the lungs, it moves to the alveoli,
which are surrounded by tiny blood vessels called capillaries. This is where gas
exchange takes place.
Oxygen typically diffuses from the alveoli into the blood running through the
capillaries. In this type of hypoxemia, the diffusion of oxygen into the bloodstream
is impaired.
Some potential causes of diffusion impairment include:
interstitial lung disease
scarring in the lungs (pulmonary fibrosis)
fluid in the lung (pulmonary edema)
COPD, specifically emphysema
Hypoventilation
Hypoventilation is when oxygen intake occurs at a slow rate. This can result in
higher levels of carbon dioxide in the blood and lower oxygen levels.
Hypoventilation can happen due to things like:
obstructed airways, like in COPD, asthma, or obstructive sleep apnea
the effects of substances like alcohol, opioids, and sedatives
a restricted ability to move your chest in order to inhale and exhale
the effects of neuromuscular diseases like Guillain-Barré syndrome or myasthenia
gravis
injuries to areas of your brain that control breathing
Low environmental oxygen
This type of hypoxemia typically occurs at higher altitudes. Oxygen in the air
decreases with increasing altitude. Therefore, at higher altitudes, each breath you
take provides you with lower oxygen levels than when you’re at sea level.
When you have low blood oxygen levels, you can experience shortness of breath
and confusion. Hypoxemia is a serious health condition that requires urgent
medical care.
Hypoxemia is when you have low levels of oxygen in your blood. When this
happens, the organs and tissues in your body don’t get enough oxygen to function
properly.
Hypoxemia is often the result of a problem with gas exchange in your lungs,
although it can have some other causes.
Gas exchange happens in the alveoli, the tiny air sacs in your lungs that are
surrounded by blood vessels called capillaries.
During gas exchange, oxygen from the air you’ve breathed in passes from the
alveoli into your blood and is then delivered to the cells throughout your body.
While this is happening, carbon dioxide leaves your blood and moves into the
alveoli, where it’ll be expelled when you exhale.
When this gas exchange is affected in some way, it can lead to hypoxemia. It’s a
serious medical situation that requires prompt medical attention.
In this article, we’ll talk more about hypoxemia, including what causes it and how
it’s treated.

This type of hypoxemia typically occurs at higher altitudes. Oxygen in the air
decreases with increasing altitude. Therefore, at higher altitudes, each breath you
take provides you with lower oxygen levels than when you’re at sea level.
Altitude based oxygen level reduction
High altitude can also be a problem for people with cardiopulmonary disease,
many of whom take long haul flights on commercial aircraft. They need to know
how their condition can be affected by the cabin altitude of the aeroplane (typically
1800-2500 m).
Although the percentage of oxygen in inspired air is constant at different altitudes,
the fall in atmospheric pressure at higher altitude decreases the partial pressure of
inspired oxygen.
At real altitude (in the mountains), the barometric pressure of the atmosphere is
much lower than sea-level environments. The result is that oxygen molecules are
spread further apart, lowering the oxygen content of each breath. As a result, the
reduced availability of oxygen in the air reduces the blood oxygen saturation in the
body. As the percentage of oxygen in the body goes down, the body struggles to
efficiently deliver oxygen to tissues, muscles and the brain. If you’re interested in
altitude as it relates to air pressure.
