Through this blog I plan to break down the oximeter and let the reader decide if they are worth it or not
I have heard of it but what actually is it?
A pulse oximeter is a medical device which fundamentally measures the arterial oxygen saturation of haemoglobin (Hb) of a patient, with a probe attached to his/her body where the blood flow is excellent for more concise results. The ideal spots are finger, toe or ear lobe which is then linked to a computerized unit. This method of measuring oxygen in blood is known as Pulse Oximetry
Or in lesser technical terms it is a medical device designed to measure the oxygen level in human blood
Okay, so how does it work?
A pulse Oximeter uses red and infrared light to detect in the patients blood stream. Infrared light would be absorbed more by hemoglobin which carries the oxygen, but red light will be allowed to pass through. On the other hand, red light would be absorbed more by hemoglobin without much oxygen but infrared light will be allowed to pass through. Once the information is gathered and transmitted to the machine or device, the ratios of red to infrared light are calculated and compared to a model table to determine the results. A good reading usually ranges between 90 to 100 saturation
Pulse Oximeters . . The Good, The bad and the Ugly - How to choose one?
- Select one that suits your needs. Larger models which come with better and more complex features are mostly used in public hospitals, while hand-held or portable fingertip pulse oximeters will be better choices for home or sport/fitness usage
- Choose one that has been tried and tested by others before. Read their reviews and testimonials for the pros and cons
- The price of the pulse oximeter can range from £50 to a £1000. Please note that an expensive one doesn't always mean a quality one, though it most cases it is. You need a device that gives you accurate results, reliable oxygen saturation readings and pulse rates
- Choose one that is user-friendly or easy to use. You wouldn't want to get one that takes hours to figure out how to operate, especially you will be operating he device yourself.
- Get one that offers a full refund if you are not satisfied with the results for at least a reasonable period of time. During this time, you may like to test the pulse oximeter against someone who can manually take your pulse and oxygen saturation measurements to compare the readings and make sure that the one you choose is the most accurate

Some tips for when searching
- If you are getting a pulse oximeter for medical use, make sure that you go for one that is FDA approved
- If you are buying one online, always research for merchant sites that have the best reputation for affordable prices, quick shipping, best warranties and customer service
- Always spend some time to research for a good pulse oximeter, than to waste money to buy one blindly.
