Earnestly, what is normal oxygen saturation?


Oxygen : What Is Normal Oxygen Saturation?

Oxygen is the most crucial element for living organisms. It is estimated that oxygen is required for 90% of our biochemical and metabolic activity. We inhale oxygen and exhale carbon dioxide as we breathe.

The majority of oxygen is delivered by red blood cells, which assist in its delivery to all regions of our bodies. The oxygen in our blood aids in the replacement of old and worn-out cells, providing energy to the body and improves immune system performance.

For living an energetic existence sufficient supply of oxygen is necessary.

You may have recently heard the term “blood oxygen levels” or “what is acceptable oxygen saturation” everywhere; since the COVID-19 epidemic broke out, it has become increasingly significant in our daily lives.

What is oxygen level?

The amount of oxygen carried by your red blood cells is measured by your blood oxygen level. Your body keeps a careful eye on the amount of oxygen in your blood. Your health must maintain a proper balance of oxygen-saturated blood. Many patients with chronic illnesses need to keep an eye on their blood oxygen levels.

How is the oxygen level in your blood measured?

An ABG (arterial blood gas) test is the most accurate approach to determine blood oxygen levels. A sample of your blood is obtained from an artery, generally the wrist, during this test.

However, an ABG test is more time-consuming, painful, and inconvenient to perform at home.

Another method for determining your blood oxygen levels is to use a device named ‘pulse oximeter.’ This device uses light absorption from the pulse to indirectly measure blood oxygen levels.

Even though it is simple, quick, and painless, this procedure may not be exact due to a few external factors that can influence the outcome.

The oxygen saturation level is a measurement of the amount of oxygen in your blood. When utilizing a blood gas, it’s referred to as a PaO2 and when using a pulse ox, it’s referred to as an O2 sat (SpO2). These recommendations will assist you in interpreting your results:

For healthy lungs, a normal ABG oxygen level is between 75 and 100 millimetres of mercury (mm Hg). Anything less than 60 mm Hg is considered low, and you may require an oxygen supply, as determined by your doctor.

However, if you use a pulse oximeter to assess your oxygen level at home, a typical level is when the SpO2 level is between 95 and 100 per cent.

If your oxygen level drops below 80-85 per cent, your brain begins to suffer negatively. If your oxygen level drops below 67 per cent, there may be a chance that your skin may become bluish, which can be fatal.

Hypoxemia occurs when your blood oxygen level falls below the normal range. The lower the level, the more severe the consequences. When your oxygen level drops, a variety of symptoms begin to appear such as Headache, dizziness, coughing, shortness of breath, wheezing, confusion, rapid heartbeat, bluish skin tone, etc.

Now you must be clear about what is normal oxygen saturation let’s move ahead.
