Which is the best pulse oximeter for sleep apnea? Read our guide to find out.
If you have sleep apnea, your energy levels drastically reduce, and so do your pulse rate and blood oxygen levels. Scientific studies1have shown that oximeters are 30 percent better at diagnosing sleep apnea in patients than traditional means.
Sleep Apnea and Blood Oxygen Levels
What Causes Oxygen Deprivation in Sleep Apnea?
When you stop breathing while sleeping, the body receives less air and this leads to low blood oxygen levels. In severe cases, the low oxygen levels can exert pressure on the left ventricle of the heart. The result will be your body creating and releasing urine as it will interpret the pressure as a need for relieving blood pressure.2
In other words, you cannot get a good night sleep when you have obstructive sleep apnea.
Check the video below for a demonstration of oxygen deprivation during sleep apnea as seen through the data released on a finger oximeter.
Recommended Oxygen Level During Sleep
Doctors can use the best pulse oximeter for sleep apnea to determine the levels of oxygen in your body in percentage form. This measurement is known as the SpO2 (or, the oxygen saturation level). The normal oxygen saturation level in the body is between 95% and 100%.
If your body oxygen saturation level is 92% or lower, this means that your vital organs are not receiving an adequate amount of oxygen. Therefore, you will be at high risk of suffering from hypoxia or may be suffering from conditions such as asthma, COPD, severe snoring, and sleep apnea
Sometimes, the blood oxygen level may drop but not for long enough or low enough to be considered unhealthy or abnormal. For example, there shouldn’t be any real worry if the blood saturation drops for a couple of seconds with 80% for two times in one night.
To monitor your blood oxygen levels during sleep, you can use a nurse pulse oximeter or go to a sleep lab to have an overnight sleep study. A pulse oximeter is useful for people suffering from sleep apnea. The device is cheaper than the cost of a sleep study and can show important information regarding your sleep quality or the effectiveness of your sleep apnea treatment.
Best Pulse Oximeter for Sleep Study (Detecting Sleep Apnea)
When worn, a pulse oximeter provides a record of your heart rate and blood oxygen saturation level. This information is essential for monitoring the quality of sleep, especially if you usually have apnea episodes when sleeping.
Watch the video below to understand why it’s important to use a portable pulse oximeter if you have sleep apnea.
Generally, sleep apnea pulse oximeters are expensive and most insurance companies do not cover them. On the other hand, pulse finger oximeters are quite cheap.

How to Use a Pulse Oximeter for Sleep Apnea
Watch the video below for an overview of how to read the information from a pulse oximeter to determine whether you had apnea episodes when sleeping:
How Does a Sleep Apnea Pulse Oximeter Work?
A sleep apnea pulse oximeter records the heart rate and your blood oxygen saturation levels. However, the device does not indicate whether an increase in heart rate or a drop in oxygen blood saturation is caused by arousals or apnea episodes from sleep.
Sometimes, drops in oxygen levels may be caused by other illnesses like COPD or asthma.
However, if you already have sleep apnea, a portable pulse oximeter can help you monitor the effectiveness of your treatment. To track your progress, simply wear the oximeter on your finger while sleeping and then check in the morning the data that would be recorded on your computer.
Bottom line is, a pulse oximeter may not help to diagnose sleep apnea, but is a great way of monitoring any treatment you may be undergoing.
Oxygen Saturation Monitor Tips
Your insurance company is not likely to buy an oximeter for home use. However, they will pay for the overnight oximetry service provided by local DME suppliers.
Generally, insurance companies do not pay for oximeter equipment, even if you have chronic obstructive pulmonary disease. (COPD). If you have COPD, you can ask your doctor to script an overnight oximetry whilst using your CPAP. Your DME provider will issue you with an oximeter that you can use overnight.
You will have to return the oximeter to the DME provider the next morning and the oximetry data will be downloaded and faxed to your ordering doctor. Depending on the data sent, the doctor can decide whether or not to order 02 supplements with our PAP.
Generally, the oximetry test is not sufficient enough to indicate whether you have sleep apnea.
However, using a pulse oximeter is helpful if you are on treatment for a breathing disorder. Moreover, the device is cheap and provides important information.
