MD300C23 Finger Pulse Oximeter

This finger pulse oximeter measures SpO2 and PR. Its lightweight, portable design makes it ideal for observation kits.

The oxygen pulse oximeter shows blood oxygen saturation level (SpO2), blood pressure pulse bar and waveform on a bright two-coloured OLED screen, making it quick and easy to take readings.

Ideal for use in hospitals, clinics, medical centres and homes.

FAQs

What is a pulse oximeter?

A pulse oximeter is a small device you place on the end of your finger to measure your pulse or heart rate and the level of oxygen in your blood. 

How to read a pulse oximeter?

In order to get a reading from a pulse oximeter, turn on the device and place it on your index or middle finger before waiting for the numbers to stabilise.

A pulse oximeter should give you two readings: a percentage and a number typically shown as beats per minute. The percentage is your blood oxygen saturation level (SpO2), and the number is your pulse or heart rate (PR).

How does a pulse oximeter work?

A pulse oximeter is a non-invasive monitoring device in which one side transmits light and the other detects it. The light-emitting side emits both red and infrared light.

By placing the pulse oximeter on the patient's finger (a translucent part of the body), light passes through, and the detector on the other side measures the changing absorbance at each wavelength.

Oxygenated blood absorbs more infrared light, whereas deoxygenated blood absorbs more red light, allowing the device to determine your blood's oxygen level.
