What is a Pulse Oximeter, and what does it measure?

The pulse oximeter is a device to monitor oxygen saturation and blood oxygen levels in the arterial blood. The arterial blood flows to parts of the body from the heart, filled with oxygen as it diffuses to tissues and cells. It is a small and portable device that easily clips on a finger and takes the reading within seconds. The device also measures heart rate. 

A pulse oximeter measures the rate of arterial oxygen. It is the oxygen carried on blood hemoglobin, aka SpO2. The device also measures heart rate that is calculated automatically while taking oxygen readings. 

How does a pulse oximeter work?

A pulse oximeter works on a simple principle of blood absorption of light, and it differs for wavelengths that go via oxygenated and de-oxygenated blood. The fingertip clip in an oximeter transmits light that emits a broader spectrum of light. It has a receiver that calculates how much amount of light goes through. The receiving end has a diode that detects the wavelength of light while the internal circuits take other calculations.

Which finger to use for a pulse oximeter?

The pulse oximeter is best used on the middle finger. It increases the reliability and accuracy of readings—a study conducted in 2015 gauges that every finger has a different result. And as per that, the middle finger produces the most reliable results. 

Specifically, the middle finger of the right hand produces the most accurate results. Also, the thumb of the right hand gives accurate readings.

What are the types of Pulse Oximeters?

There are two types of pulse oximeters – Medical Grade and Home & Sports Use. The former is used by doctors and other medical professionals and are purchased through medical equipment manufacturers. In contrast, the latter can be bought commercially via brick and mortar stores and even online via portals like Amazon.

Should I really buy a pulse oximeter for home use?

Yes, you should. Especially in the current world order, it won’t hurt to have a home device to measure vitals like blood oxygen levels and heart rate. If you are suffering from any respiratory issue or have a family member who does, it only makes sense to have an oximeter at home—an investment worth making for your health and peace of mind.
