Blood oxygen levels measured by using a pulse oximeter.

How to increase Blood Oxygen Level


Blood oxygen level is the amount of oxygen circulating in the blood. Most of the oxygen is carried by red blood cells, that accumulate oxygen from the lungs and deliver it to all areas of the body.

The body tightly promotes blood oxygen levels to keep them within a specific range, so that there’s enough oxygen for the needs of every cell in the body.

A person’s blood oxygen level is an index of how well the body distributes oxygen from the lungs to the cells, and it may be important for people’s wellbeing.

Normal and low blood oxygen levels:

A standard blood oxygen level fluctuates between 75 and 100 millimeters of mercury (mm Hg).

A blood oxygen level below 60 mm Hg is deemed low and may require oxygen supplementation, based on a physician’s decision and the patient instance.

This usually means that your system has difficulty delivering oxygen to everyone its cells, tissues, and organs.

How is blood oxygen level measured?

The most effective means to monitor blood oxygen levels is via an arterial blood gas or ABG test. This process is extremely true, but it can be somewhat painful.

An ABG test can be difficult to do in your home, so an individual may want to do an alternative evaluation, with a small device known as a pulse oximeter.

A pulse oximeter is a little clip that is often put on a finger, although it can also be employed on the toe or ear. It measures blood oxygen indirectly by light absorption by means of an individual’s heartbeat.

Although the pulse oximeter test is easier, faster, and not painful, it isn’t as accurate as of the ABG test.

This is because it may be influenced by variables such as dirty fingers, glowing lights, nail polish, and poor circulation to the extremities.

For people that want to purchase a pulse oximeter, there’s a range of easy-to-use devices available online.

Symptoms of low blood oxygen level:

Shortness of breath and a rapid heartbeat are possible symptoms of low blood oxygen levels.

Low blood oxygen levels Can Lead to abnormal circulation and lead to the following symptoms:


Hypoxemia, or oxygen levels under the normal values, could be due to:

  • Insufficient oxygen from the atmosphere
  • An Inability of the lungs to inhale and send oxygen to cells and tissues
  • The inability of the blood to circulate to the lungs, accumulate oxygen and then transport it around the entire body

Several health conditions and scenarios can contribute to the above factors, such as:

  • Asthma
  • Heart diseases, such as congenital heart disease
  • High elevation
  • Anemia
  • Chronic obstructive pulmonary disease or COPD
  • Interstitial lung disorder
  • Emphysema
  • Acute respiratory distress syndrome or ARDS
  • Pneumonia
  • Obstruction of an artery in the lung, for instance, Because of a blood clot
  • Pulmonary fibrosis or scarring and damage to the lungs
  • Presence of air or gas in the chest Which Makes the lungs collapse
  • Excess fluid in the lungs
  • Certain medications, including some narcotics and painkillers

When to See a Physician

Folks should visit a doctor if they:

  • Experience acute and sudden shortness of breath
  • Experience shortness of breath when at rest
  • Wake up unexpectedly with shortness of breath or a feeling of choking
  • Are at high altitude (over 8,000 feet or 2,400 meters) and experience severe shortness of breath with a cough, rapid heartbeat, and fluid retention

Remedy & Treatments:

Remedy for reduced blood oxygen levels comprises getting supplemental oxygen. This may be performed in the home when it’s called home oxygen therapy or HOT.

Some precautionary measures could be taken by people to lessen symptoms of shortness of breath and enhance overall health and quality of life.

These include:

Bottom Line:

Low oxygen levels in the blood aren’t necessarily dangerous and can happen in people who may recuperate, or in healthy people when they’re at high altitude.

These people don’t have to track their blood oxygen levels frequently.

But individuals with chronic lung diseases, such as COPD, pulmonary fibrosis, or emphysema, may have blood oxygen levels under the standard because of their illness.

These people may require regular blood oxygen monitoring.

Individuals with low blood oxygen may make lifestyle changes, such as not smoking or enhancing their diet and exercise habits, as well as being treated with supplemental oxygen.

Ask your friends and loved ones for support.

If you’re feeling anxious or depressed, consider joining a support group or seeking counseling. Believe in your ability to take control of the pain…
