Pulse oximeters are portable, non-invasive medical devices normally worn on the finger that measure the oxygen saturation of a person’s blood. These devices are used in medical facilities such as hospitals, physicians’ offices, and sleep centres, but can also be used at home. Pulse oximeters are available for children and adults. The fingertip oximeter with the smallest openings could be used for pre-school to school age children.
Traditionally used for medical purposes, pulse oximeters also measure pulse rate. Some measure Perfusion Index (PI) which measures pulse strength. Athletes, including runners, swimmers, and rock climbers, also use pulse oximeters.
Features to look for;
- Levels of accuracy - A warning light on some oximeters notify the user of interference or an inaccurate reading.
- Alarms - Some users or clinicians may need an oximeter with audible alarms in order to indicate low oxygen saturation levels.
- Readability of displayed measurements – Some people prefer a colour oximeter or larger numbers or a screen readout that can rotate.
- Durability and battery life – If using frequently or for multiple patients, the user may prefer a rugged design that withstands dropping and humidity.
It is easy to use and can give a reading within 5 seconds. Simply insert your finger into the oximeter and press the ON button to take a measurement. For an accurate reading, make sure your finger is still and stationary. Warm up your hand if it is cold to ensure sufficient blood circulation. This is important so that when using the finger oximeter with a child he or she tries to keep as still as possible in order to avoid an incorrect reading.
Features

What is the best oximeter for spot checks at home?
A fingertip oximeter is the most common type for spot checks at home. These small devices fit conveniently on the end of the finger, automatically turn on to display the oxygen saturation level and pulse, and turn off when removed. If you anticipate the oximeter being used by many persons, transported to different locations or carried in a supply bag, durability is something you should consider buying an oximeter that is designed with extra durability.
