Low sleep apnea oxygen level is a sign that your treatment for sleep apnea is not effective. Patients with breathing problems during sleep (sleep apnea, COPD) often have low oxygen levels in their blood. Keep in mind that anything below 90% oxygen level is dangerous to your body and require intervention. Normal SaO2, or% oxygen saturation, is 95–99% at sea level. This goes down with moving to a higher altitude. It becomes a problem at 85–90% - called hypoxia. 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.

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
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.

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.
Oxygen levels don’t have to be confusing. Let’s make sense of them together.
Let’s start with the obvious: what are oxygen levels? And from there, what do they mean? If you live with chronic obstructive pulmonary disease (COPD), pulmonary fibrosis (PF) or emphysema, oxygen levels are an undoubtedly important measurement, and here’s why: they allow you to measure how much oxygen your red blood cells are carrying.
Why is that important?
The importance behind this metric is that by measuring your blood oxygen levels, you can alter your behaviors and lifestyle to positively improve these levels and possibly help reduce your symptoms and feelings of breathlessness. In essence, the oxygen that is being carried by your red blood cells throughout your body allows your body to thrive and maintain homeostasis (when your body runs healthily). To aid in this process, the delivery of oxygen through red blood cells in your blood cells is vital.

So, how can I affect this?
There are a variety of ways to positively improve your blood oxygen levels to help relieve your symptom expression and boost your energy levels. And with your health in mind, the Lung Health Institute is here to help by giving insight to your Oxygen Levels: What Do My Numbers Mean?
Oxygen Levels- An Overview
As we’ve mentioned above, the measurement of your oxygen levels is pretty important to your overall health. It allows you to adjust and change your behavior based on your oxygen levels for the betterment of your breathing and condition. But what are blood oxygen levels and what do they mean?
Here’s a quick anecdote:
Imagine for a second that your blood vessels make up a giant subway network. The tunnels of this network are your veins and the train itself is your blood. Multiple carts (your blood cells) make up the train, and the people inside them are oxygen. As this subway (again your blood) travels through the network (your body), it’s dropping people off at various stops within your body. The question, however, is how many people (oxygen) are in each car of the subway? And is there a way to pack more in them?
This fundamental scenario is blood oxygen saturation in a nut shell and explains the importance of your body’s ability to retain oxygen within your red blood cells. In short, you want each of these cells jam packed with oxygen for delivery throughout your body to maintain and boost your energy levels and overall health.
So, What’s Normal and What Isn’t?
Your body’s oxygen levels can be measured using a variety of different techniques:
- Arterial blood gas test (ABG)—which measures your blood’s oxygen level by drawing blood.
- Pulse oximetry—which places a clip device on your finger and measures O2 levels.
A normal ABG blood oxygen level for healthy lungs will usually fall between 80 and 100 millimeters. If using a pulse oximeter, this reading should typically be between 95 and 100 percent.
In the case of severe COPD on the other hand, an expected pulse oximetry level is likely to be between 88 to 92 percent. Some people’s oxygen level measurements may be lower.
When your blood oxygen level gets too low (hypoxemia), there are several symptoms that you will be able to recognize:
- shortness of breath
- chest pain
- confusion
- headache
- rapid heartbeat
- possible cyanosis (blue discoloration of the nail beds, skin and mucus membranes)
Methods that May Improve My Oxygen Levels
Thankfully, to combat low blood oxygen levels there are several ways to raise them. First, if your blood oxygen level is particularly low, it may be wise to consider getting on supplemental oxygen therapy if your doctor hasn’t already prescribed it. In addition, always talk with your doctor about your oxygen level questions and concerns.
Adding to this, by raising the amounts of hemoglobin within the body through the ingestion of specific foods, it’s possible to positively impact your blood oxygen levels. When your body has the nutrients it needs, it has a better ability to deliver oxygen more efficiently as well.
To start:
- Eat Shrimp—they are a good low calorie protein and filled with important vitamins, nutrients and antioxidants.
- Have an Orange—there are several things to love about the orange, particularly orange juice. The bonus is that they’re excellent sources of fiber, vitamin C and other critical acids and nutrients.
- Drink Some Almond Milk– Vitamin D is important, but so is avoiding any excessive phlegm build-up. Instead, pick up some almond milk. It tastes better and won’t leave you as gassy or bloated.

Moving Forward with Your Oxygen Levels
Living with a chronic lung disease like COPD, pulmonary fibrosis and emphysema doesn’t have to be as difficult as it may seem. By taking the time to better understand your disease and how to address issues such as your blood oxygen level, it’s possible to improve your overall health and quality of life. Although these steps can be difficult as they require changing personal behavior from diet and exercise to your medication, change is possible.
With a few behavioral changes, it’s possible to greatly affect the pronouncement of symptoms within those with COPD, emphysema and pulmonary fibrosis. However, when lifestyle changes fail to improve your quality of life in the way that you may expect, it may be time to consider cellular therapy. Rather than addressing the symptoms of lung disease, cellular therapy may directly affect disease progression and may improve quality of life.
