Best Pulse Oximeters

Keeping track of your own health is essential to maintaining your quality of life as you age. There are many health concerns that can affect your blood oxygen levels, including COPD, asthma, emphysema, and heart disease. Using a pulse oximeter to measure the amount of oxygen in your blood so you can talk to your doctor if your oxygen levels drop too low before a minor problem becomes a major health risk.

What Do Finger Pulse Oximeters Do?

The best pulse oximeters to use at home are fingertip models. These simply clip onto your fingertip and provide a digital readout of you blood oxygen levels. It’s a non-invasive test (no needles) using a sensor to measure light wavelengths to measure the saturation of oxygen in your blood hemoglobin.

Normal saturation is typically between 75 and 100. If yours falls below this, you may feel symptoms such as lightheadedness, headache, dizziness, rapid breathing, shallow breathing, restlessness, chest pain, confusion, and wheezing. If you have any of these symptoms or your blood oxygen level is at or below 75, contact your doctor.

When choosing a choosing the best pulse oximeter for your needs, talk to your doctor first. If you have a serious, life-threatening condition and need to constantly monitor your oxygen saturation precisely, you may need a more expensive, medical grade device or a handheld oximeter, which will be more accurate. For at-home use for most seniors, fingertip units are the easiest to use and fall within the degree of accuracy needed.

How to Find the Best Finger Pulse Oximeter

Always check online pulse oximeter reviews before purchasing. By comparing the pros and cons of various brands, you can get a better idea of which ones offer the features that are important to you at the price you want. Fortunately, most pulse oximeters are relatively affordable, costing less than $50.00 plus the cost of a few inexpensive batteries.

Before purchasing a finger pulse oximeter, talk to your doctor. He or she can steer you toward the best kind for your needs. Some measure only your blood oxygen levels, while others will also monitor your heart rate. Once you determine which of these you need, consider each of these features when reading through pulse oximeter reviews:


Some oximeters are more accurate than others. Some will indicate with a warning light when a reading may be inaccurate so you know when your device may not be function properly.

Alarms for Low Oxygen Levels

If you have medical issues that are a real concern when your oxygen levels drop below a certain level, an audible alarm can alert you quickly so that you can contact your doctor immediately.

Clear Display

The display should be bright, clear, and easy to read. Screens vary in color and size, as do the numbers. If you may have to read it in different lighting conditions, take this into consideration as well.

Battery Life or Plug-In Feature

How long do you need your monitor to last and how long will you be using it each day? If you will be checking your blood oxygen saturation twice a day, your batteries will last a fairly long time. If you will have to check multiple times day and night, you may want to consider a rechargeable device to prolong the life of your finger pulse oximeter.


How hard are you on your devices in general? Will you be throwing it in your purse, taking it along on hikes and kayaking trips, or will it sit by your bedside or on the coffee table? Consider how rugged your oximeter will need to be so you won’t need to be constantly replacing it.

A Few Tips for Getting an Accurate Oxygen Saturation Reading

When you get your new pulse oximeter, there are a few things to keep in mind to make sure it works properly and ensure you’re getting an accurate oxygen saturation reading every time:

  • Take your pulse oximeter to your doctor’s office and ask to calibrate it to the one our doctor or nurse uses. Comparing the readings a few times will indicate how accurate yours is and whether it reads a few points high or low.
  • Always use your pulse oximeter in a resting state. You should be seated when you attach it to your finger, then rest your hand on the arm of your chair or on your chest. Between waist and heart level is best. Lower or higher will throw the reading off.
  • Warm your hands prior to attaching the oximeter by briefly rubbing your hands together. Cold hands will mean low blood flow, which will give an inaccurate reading.
  • Remove nail polish before using a pulse oximeter. Nail polish interferes with the reading.

If you continue to have difficulty getting an accurate reading, talk to your doctor.
