What happens when Oxygen Levels drop?

If your blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to cells throughout the body to keep them healthy. Lack of oxygen can cause minor problems like headaches and shortness of breath. In severe cases, it can interfere with heart and brain function.

The body monitors blood oxygen levels to keep them within a specific range so that there is enough oxygen for each cell’s needs.

A person’s blood oxygen level is an indicator of how well the body distributes oxygen from the lungs to the cells, and can be important to a person’s health.

A blood oxygen level that is too low compared to the average level for a healthy person may be a sign of a condition known as hypoxemia. This develops when the body has difficulty getting oxygen to all of its cells, tissues, and organs.

What is hypoxemia in medical terms?

Blood is the body’s efficient transportation system and deals with two basic products: nutrients and oxygen.

Organs and muscles need both to function, so a deficiency of nutrients or oxygen can cause health problems.

Both hypoxia and hypoxemia refer to the body’s oxygen levels.

Because they have similar spellings, these two conditions are often confused. While they can co-exist, they are quite different.

In short, hypoxemia refers to low oxygen content in the blood, while hypoxia means low oxygen supply to body tissues.

In many cases, hypoxemia points to hypoxia as low blood oxygen concentration often impairs oxygen delivery to tissues.

How to increase oxygen level immediately?

There are a number of things you can do to help increase your blood oxygen level. In the immediate short term:

Stand or sit up straight. Instead of lying down, which can put pressure on your lungs and make it hard to breathe.

If you have a cold or the flu, shortness of breath can lower the oxygen saturation in your blood. Coughing can loosen secretions and clear the airways.

Get outside, fresh air is good for your lungs and generally has higher oxygen levels. However, if it’s too hot or too cold, that can make it hard for you to breathe.

Drink plenty of water, properly hydrated lungs are more efficient at dispersing oxygen into the bloodstream.

Take slow deep breaths, this should increase the amount of air going into your lungs.

Oxygen levels saturation

Your oxygen levels indicate how well your heart and lungs are delivering oxygen to support your body’s essential functions.

These include supplying energy, repairing cells, and keeping the immune system functioning.

Doctors often refer to blood oxygen saturation as the “fifth vital sign,” along with heart rate, respiration, temperature, and blood pressure.

Doctors and other health professionals use a small device called a pulse oximeter to measure oxygen saturation levels.

These levels indicate the percentage of oxygen carried by hemoglobin in the blood compared to the maximum amount it could carry.

The results help determine if there is a need for medical treatment, such as supplemental oxygen.

There are variables that affect how doctors interpret blood oxygen levels, such as whether or not someone has a chronic lung condition.

However, in general, the levels that medical professionals consider to be normal, borderline, and low are as follows:

Levels saturationBlood oxygen saturation
Normal95–100%
Borderline91–94%
Lowunder 91%
