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. The human body is roughly 60 percent water, so it cannot be understated how critical water. 2 days ago  In many cases, low, critical oxygen levels could also lead to loss of consciousness, cause an inability to stay awake or even get up, apart from the above-listed critical warning signs of danger.

Low blood oxygen, known as hypoxemia, means that the level of oxygen in the blood has dropped below average, normal levels, due to one or more of many different causes. Under most circumstances, breathing room air, normal readings range from 95 to 100.

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?

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.

Management and Treatment

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
