Best Pulse Oximeter for the Elderly: Reviews

Zacurate Pro Series 500DL


This Zacurate Pro pulse oximeter is easy to use, provides accurate readings, and comes at a fair price.


The Zacurate Pro Series 500DL can provide you with several types of readouts, including blood oxygen saturation, pulse rate, and pulse strength, and it does so with great accuracy and speed. It takes only 10 seconds to get accurate readings.

Due to the smart spring chamber, the Zacurate Pro Series 500DL is easy to open and close, plus it should fit fingers of all sizes, except for the very largest of fingers. Keep in mind that the finger chamber is hypoallergenic and latex-free.

Deluxe SM-110 Two Way Display Finger Pulse Oximeter

If you are looking for a simple yet effective pulse oximeter, which’s not too expensive, this model from the Santamedical Store is a good one to consider.


The Santamedical Deluxe Oximeter provides blood oxygen saturation, pulse strength, and pulse rate readouts, and it uses some high-class tech to ensure the utmost accuracy. Moreover, it takes only 10 seconds to obtain accurate readings.

This unit features a very bright, high-contrast, and easy-to-read display, so you can see what it says even without glasses on. Also, the display can rotate, so it’s easy to read from any angle.

In terms of convenience, the Santamedical Deluxe Oximeter is about as compact and lightweight as it gets, and the latex-free chamber should be able to accommodate most finger sizes.

This unit comes with two AAA batteries included; a single pair of batteries should last for around 30 hours.

Metene Pulse Oximeter  


This is another simple, affordable, and accurate pulse oximeter for you to consider. It’s nothing special, but it works.


What’s nice about the Metene Pulse Oximeter is that it comes with a lanyard, plus it’s relatively small and portable, making it ideal for being on the go and for always having it on your person.

What is really impressive about this model is that it can get accurate readings in as little as five to eight seconds. It uses a special MCU chip and sensor to ensure the highest accuracy possible when measuring blood oxygen saturation, pulse intensity, and pulse rate. It’s accurate to within ±2%.

The Metene Pulse Oximeter uses two AAA batteries, which will need to be replaced regularly. However, a single pair can last for around 30 hours, and you also get a low battery alert. We like the large, bright, and easy-to-read LED display, although it would be nice if it could rotate.


  • Compact and portable
  • Good battery life
  • Bright display with large characters
  • Very accurate readings
  • Can measure SpO2, pulse rate, and pulse intensity

The mibest OLED Finger Pulse Oximeter is really cool, and a lot of it is thanks to the high-quality OLED display.

The resolution on this oximeter is excellent; there is a lot of contrast between the letters/numbers and the background, and the brightness can be adjusted. There are four display modes, and best of all, the screen can rotate to all four directions for super easy reading.

This unit can measure blood oxygen saturation, pulse rate, and pulse intensity. It does so with an excellent accuracy rate of +/-2%, and it can take readings in as little as 10 seconds.

The mibest OLED Finger Pulse Oximeter is very small and portable and comes with a lanyard. It is large enough to fit most fingers with ease.


  • Great accuracy

  • Portable
  • Easy to use


  • Won’t fit very large fingers
  • Limited durability and build quality

Alcedo Pulse Oximeter Fingertip


This model is not much different from any of the others reviewed so far. It’s small and straightforward, easy to use, accurate, and it won’t cost you a fortune either.


The Alcedo Pulse Oximeter features a very large, bright, and dual-color OLED display that allows for brightness adjustment. It is relatively easy to read, although the display does not rotate.

This unit features one-button functionality, so you can get accurate blood oxygen saturation and pulse rate readings, all in as little as ten seconds. However, it does not appear to measure pulse intensity.

The Alcedo Pulse Oximeter is designed to be very compact and lightweight, plus it also has a lanyard for increased portability. It’s small enough to be portable, yet large enough to fit virtually all fingers.


  • Accurate PR and SpO2 readings
  • Very fast
  • Compact and portable
  • Great display
  • Good price


  • Battery life could be better
  • Overall durability is a bit limited

Buyer’s Guide

Before you buy a pulse oximeter, let’s go over some of the essential features to consider.


The pulse oximeter should be accurate to within ±2%, no less. An accuracy any lower and the device becomes useless.


You want to go for an excellent display – an OLED display or LED at the very least. It should have good contrast with large writing; it should rotate for easy reading. If possible, adjustable brightness is a good bonus to have.


A good pulse oximeter should be small enough to fit in a pocket, and if you can, get one with a lanyard, so you don’t lose it.

Final Verdict

The bottom line is that the pulse oximeters we reviewed today are all great for seniors. The differences you need to consider are how many types of readings the unit in question can take, the speed and accuracy of readings, portability, and battery life.
