how to increase oxygen level at home

Practice breathing exercises.

Pulmonary rehabilitation experts recommend using simple breathing exercises like pursed-lip breathing and deep belly breathing to open your airways and increase the amount of oxygen in your body.

The blood in your body delivers oxygen to all of your cells. When you breathe and draw fresh oxygen into your lungs, red blood cells bind with the oxygen and carry it through your bloodstream. On a cellular level, oxygen helps replace cells that wear out, supplies you with energy, supports your immune system, and more. That's why it's important to make sure your blood oxygen level isn't too high or too low. 

You can naturally increase your blood oxygen level or discuss different methods with your doctor to maintain or elevate your blood oxygen level.

How Is Blood Oxygen Level Measured?

You measure blood oxygen, also called oxygen saturation, with a pulse oximeter. It's a small device that clips to your finger (or another part of your body) and determines the ratio of red blood cells that are carrying oxygen to those that are empty.

Checking or monitoring blood oxygen levels is non-invasive and doesn't hurt. There are no known risks or dangers of using a pulse oximeter to measure your blood oxygen level.

A pulse oximeter emits light that passes through your fingernail, skin, tissue, and blood to a sensor on the other side. The device measures how much light passed through without being absorbed by tissue and blood. It then uses that measurement to calculate how much oxygen is in your blood.

What Are Typical Levels of Blood Oxygen?

Your blood oxygen level helps you know how well your lungs, heart, and circulatory system work. A typical blood oxygen level for a healthy person ranges between 95% and 100%. This means that nearly all of the red blood cells are carrying oxygen to your cells and tissues.
