When this happens, it can lower your blood’s oxygen saturation level.

They also can contribute to low oxygen levels in the blood.

Other Causes of Low Oxygen Levels

A drop in oxygen saturation in the blood is calledhypoxemia.

The sample is immediately analyzed by a machine or in a lab.

Unlike the ABG test, pulse oximetry does not involve a needle.

Instead, the test uses a sensor to read wavelengths reflected from the blood.

The probe is attached to your finger, earlobe, or another place on the body.

Some studies have shown that the right middle finger works best.

In some people, the right thumb may also work well.

A pulse oximeter can give results on a screen in just a few seconds.

Most oximeters work best when used on the middle finger.

Nail polish can interfere with oximeter measurement.

Even some smartwatches even have this feature.

it’s possible for you to also buy a pulse oximetry equipment at your local pharmacy or online.

What Is a Dangerously Low Oxygen Level?

When this happens, it’s calledhypoxia.

If the level falls for a short time, permanent damage isn’t likely.

Your cells can adapt to a lack of oxygen when the deficiency is small.

But repeated episodes (triggered by a lung condition orsleep apnea, for example) can cause damage.

A level that falls to 88% or less requires immediate care.

Hypoxia usually happens because there is not enough oxygen in the blood (hypoxemia).

Treating Low Oxygen Saturation

Generally speaking, an oxygen saturation level below 95% is considered abnormal.

This should be evaluated by a healthcare provider.

An oxygen saturation level below 90% requires emergency medical attention.

If hypoxia lasts longer, it can lead to coma, seizures, and brain death.

It is very important to find out the cause of low oxygen saturation so the problem can be fixed.

The full treatment plan will depend on the cause of the low saturation levels.

Cardiovascular Conditions

In circulatory conditions like heart disease, impaired blood flow reduces oxygen delivery.

Sometimes, ared blood cell transfusionis necessary to increase a person’s level of healthy red blood cells.

Normal oxygen saturation for healthy adults is usually between 95% and 100%.

An oxygen saturation level below 95% is not normal.

A level under 90% requires emergency care.
