Healthy lungs keep the blood oxygenated at a level between 95 and 100%—if it dips below 92%, it’s a cause for concern and a doctor might decide to intervene with supplemental oxygen. A blood oxygen level test, also known as a blood gas analysis, measures the amount of oxygen and carbon dioxide in the blood. When you breathe, your lungs take in (inhale) oxygen and breathe out (exhale) carbon dioxide. If there is an imbalance in the oxygen and carbon dioxide levels in your blood, it can mean your lungs aren't working well. I Just was released from hospital. Spent 10 days with 7 in ICU. Pneumonia was the culprit and arrived at the er with 46% oxygen level. Don’t remember most of the time there but I do remember hallucinating and talking to people who weren’t there. Hypoxemia occurs when levels of oxygen in the blood are lower than normal. If blood oxygen levels are too low, your body may not work properly. Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath.
Overview
What is hypoxemia?
Hypoxemia occurs when levels of oxygen in the blood are lower than normal. If blood oxygen levels are too low, your body may not work properly.
Blood carries oxygen to the cells throughout your body to keep them healthy. Hypoxemia can cause mild problems such as headaches and shortness of breath. In severe cases, it can interfere with heart and brain function. Hypoxemia that causes low oxygen levels in your body’s tissues is called hypoxia. Sometimes people use the two terms interchangeably, but they are not the same thing.
Symptoms and Causes
What causes hypoxemia?
A variety of conditions and circumstances can interfere with the body’s ability to deliver normal levels of oxygen to the blood. Some of the most common causes of hypoxemia include:
- Heart conditions, including heart defects
- Lung conditions such as asthma, emphysema, and bronchitis
- Locations of high altitudes, where oxygen in the air is lower
- Strong pain medications or other problems that slow breathing
- Sleep apnea (impaired breathing during sleep)
- Inflammation or scarring of the lung tissue (as in pulmonary fibrosis)
What are the symptoms of hypoxemia?
Oxygen Level In Human Body
Symptoms of hypoxemia vary depending on the severity of the condition. They include:
- Shortness of breath
- Fast heartbeat
- Coughing
- Confusion
- Bluish color in skin, fingernails, and lips
Diagnosis and Tests
How do doctors diagnose hypoxemia?
To diagnose hypoxemia, your doctor will do a physical examination to listen to your heart and lungs. Abnormalities in these organs can be a sign of low blood oxygen. Your doctor may also check to see if your skin, lips, or fingernails look bluish.
Doctors use tests to check your oxygen levels, including:
- Pulse oximetry: A sensor that slips over your finger measures the amount of oxygen in your blood. Pulse oximetry is painless and noninvasive. Many doctors use it routinely each time you visit.
- Arterial blood gas test: A needle is used to take a blood sample from your artery to measure the levels of oxygen in your blood.
- Other breathing tests: These might involve breathing into tubes that are connected to computers or other machines.

How do doctors treat hypoxemia?
Treatment for hypoxemia aims to raise the levels of oxygen in the blood. Doctors can use medications to treat underlying conditions that cause hypoxemia. These medications are often given through an inhaler that enables you to breathe the medicine into your lungs.
In more severe cases, your doctor may prescribe oxygen therapy. People typically receive extra oxygen through a device called a cannula (tube) that is clipped to the outside of the nose, or through a breathing mask. The location and amount of time people receive oxygen therapy is based on individual needs. You may receive oxygen at home, with a portable machine while you travel, or in the hospital.
What are the complications or side effects of hypoxemia?
If your blood does not have enough oxygen, it cannot deliver enough oxygen to the organs and tissues that need it. This situation can be fatal if severe in the short term and can affect the heart or brain if it persists over a long period of time.
Prevention
Can hypoxemia be prevented?
There are steps you can take to prevent hypoxemia from returning after treatment. To increase the oxygen levels in your blood, your doctor may recommend:
- Deep breathing exercises
- Mild exercise such as walking or yoga
- Eating a healthy diet
- Drinking plenty of water
- Quitting smoking
Outlook / Prognosis
What is the outlook for people with hypoxemia?
Hypoxemia symptoms can go away with treatment. Depending on the cause, people with hypoxemia may require treatment once or on an ongoing basis. Your doctor will work with you to manage the condition so you can live an active, healthy life.
Living With
When should I call a doctor regarding hypoxemia?
Contact your doctor if you experience symptoms of hypoxemia. Early diagnosis and treatment can help ensure the condition does not get worse and cause dangerous complications.
