Saturation, pulse oximeters and everything you need to know about it 

With the pandemic’s beginning, we all started using words not known before, such as “saturation”. Let’s figure out what this indicator is and how to measure it.

1. How to measure saturation?

The most affordable option to determine whether saturation is typical is to use a pulse oximeter. It is a compact device that measures the percentage of oxyhemoglobin in the blood in seconds.

The hospital also uses a pulse oximeter or determines blood gas composition in the laboratory. A blood sample is taken from an artery or vein to do so. It is not a routine analysis and is usually done in case of severe diseases.

2. What is saturation?

Saturation is an indicator of blood oxygen saturation. If your saturation level is low, it might signify some lung problems.

It became especially relevant after the appearance of new coronavirus infection. One of the main complications of COVID-19 is viral pneumonia. If you notice in time that a person does not have enough oxygen, it will be easier to help him.

3. What oxygen level in adults’ blood is considered normal?

The norm of saturation for a healthy person is when 95% or more of hemoglobin is associated with oxygen. That is saturation – the percentage of oxyhemoglobin in the blood.

With COVID-19, it is recommended to call a doctor when saturation decreases to 94%. Saturation of 92% and below is usually considered critical. A person with such a low oxygen index in the blood requires urgent medical intervention.

There are exceptions, however. For example, in severe chronic obstructive pulmonary disease, common in smokers, the saturation rate can be from 88% to 92%. Usually, such people’s bodies are adapted to a lower level of oxygen. If you have a pulmonological disease, your doctor will tell you which saturation indicator should be an alarm signal.

4. What are the reasons for the low oxygen levels in the blood?

It can happen for various reasons. For example, problems may arise with blood or respiratory system diseases.

The latter is just typical for COVID-19. After pneumonia, fibrosis of the lungs often occurs when, due to the disease, the “breathing” lung tissue is replaced by connective tissue. Compare it to closed windows. You would be happy to breathe, but fresh air does not pass through tightly closed windows.

Another reason is blood diseases — for example, frequent anemia. When there are not enough red blood cells or hemoglobin, oxygen has nothing to move around the body. In this case, the saturation also falls below the norm.

5. What happens when oxygen becomes scarce?

Shortness of breath, chest pain, confusion, headache and rapid heartbeat, cyanosis of the nasolabial triangle and fingertips – such unpleasant symptoms can appear if the oxygen level in the blood begins to drop.

6. Do I need to know my saturation?

As a rule, no. An exception is if you have diseased lungs and observe the disease’s dynamics.
