Best Pulse Oximeter for Monitoring Sleep Apnea

Sleep apnea leads to low energy levels, and this influences your pulse rate and blood oxygen levels. Oximeters have been successfully used to diagnose up to 30% more patients, compared to using traditional means alone.

The best pulse oximeter for sleep apnea can determine the levels of oxygen in your blood and then give the result in percentage form. This is referred to as your SpO2 (also known as oxygen saturation level). Normal oxygen levels are usually between 95% and 100%.

Any levels from 92% and lower are dangerous as this can cause Hypoxia – when your vital organs are not receiving the right amount of oxygen. The best pulse oximeter for home use can also detect your pulse (heart) rate.

How Does a Pulse Oximeter for Sleep Apnea Work?

Describing in detail what a pulse oximeter does and how it works might confuse users even more. Simply put, light is passed through your finger, then the light which was absorbed by the oxygenated blood in your finger is measured by the device. Basically, that means that the oximeter looks at how the light that has transferred through (gone through) your finger scans before and after and uses that information to know how much oxygen is in your blood. Still not sure how it works?

When using any pulse oximeter while you sleep, it will measure how your blood oxygen levels fluctuate or stay the same during sleep. If your blood oxygen levels are consistently above 95%, you are fine. But if your blood oxygen levels drop below this during the night, you should be made aware of it. This is when an oximeter with an alarm would be most effective.

How to Maximize the Benefits of Your Pulse Oximeter

You can add to the beneficial use of a pulse oximeter by doing your part as well. Here are some tips to maximize the benefits of your pulse oximeter:

Follow the right kind of diet:

  • You should try to cut your salt intake completely, or at least consume much less.
  • Add lots of fiber and potassium to your daily diet (consult your doctor) and try to get your blood pressure on a healthy level. You need about 28 grams of fiber a day; food that will help with this includes avocado, sweet potatoes, broccoli and apples with their skin. For potassium eat bananas, apricots, and spinach. Also remember to exercise regularly, focusing on cardiovascular exercises that will improve your blood flow as well as your heart's health.

Use the pulse oximeter efficiently:

  • Using your pulse oximeter should be an aid in dealing with and treating sleep apnea. Use your pulse oximeter throughout the entire night to get the best results. Your device will measure your heart rate and blood oxygen levels and can help to determine if your current treatment is being effective by showing any improvements in your blood oxygen levels and heart rate.

Common Terms

To be sure that you're using your device correctly you have to understand it correctly. Here are some of the terms you'll come across when using your oximeter:

#1. Oxygen Saturation (SpO2)

Oxygen saturation is a somewhat fancy way of referring to how much oxygen you have in your blood

#2. Pulse Rate

Your pulse rate merely is your heart beats/minute. When you have sleep apnea, you need to know what your pulse rate is during the night and how it changes.

#3. Perfusion Index (PI)

The Perfusion index is a way to tell of your O2 saturation reading is accurate. If your perfusion index is below 0.4%, you should know that your oxygen reading is not as reliable. The blood flow in the peripheral blood vessels is measured with the perfusion index.

Tips on Using a Pulse Oximeter

If you've never used a one before, you could be a little bit confused with how precisely this little device should be used. Usually, a pulse oximeter would have a manual included, but if yours didn't, or you lost it, here are some tips to make using your product correctly and to its full potential.

Different features

Every pulse oximeter comes with its own unique characteristics. Most of the features are universal, though, so you could expect all of them to have at least a few of these:

Size - The size of your pulse oximeter is essential to ensure that your finger will fit well and you will get the most accurate readings possible. Most pulse oximeters will be available in sizes from 0.3 inches to 1 inch. If you're buying online, you should measure your finger and look at the information given about the product.

Battery life - Most pulse oximeters will come with batteries included, and in general, they will have to be replaced sooner or later. Usually, a battery life indicator will let you know that battery life is running low and you should buy new ones. Some pulse oximeters can be charged with a USB cable, so if replacing batteries is a nuisance to you, look out for a pulse oximeter with this feature.

Measurement result display - The majority of pulse oximeters will display the results of your measurements on an LED screen. The sizes of these screens vary, and you should choose one with a screen big enough for you to see the results clearly.

Alarm systems - Almost all pulse oximeters will have built-in alarms to alert you to a number of things like low battery, heart rate, and oxygen levels.

Return policies and Warranties - Any good pulse monitor will come with a good warranty and a good return policy. You should always keep this in mind when shopping for a new pulse oximeter.

Now for the practical part

Wash your hands before using for the most accurate results. Also, remove any nail polish from the finger that you'll be using.

Your hands should be warm when you use your oximeter. Cold hands won't have enough blood flow for accurate measurements. You can warm your hands by simply rubbing them together.

Don't use your pulse oximeter in an area with too much light. It works by emitting light to take measurements and if you're in an area with a lot of bright light, it will interfere with this process and could cause way inaccurate results.

Final Thoughts

If you suffer from sleep apnea, you are probably looking for ways to treat your condition and stay healthy. Using the best pulse oximeter for sleep apnea will be a valuable tool that will help you monitor your heart rate and blood oxygen levels, two critical factors for people with sleep apnea.

Share all the data you get from your device with your doctor to utilize the aid of your oximeter and start treating your sleep apnea.
