Pulse Oximetry for Schools

Learn how pulse oximetry can help keep students and staff safe in their return to school

"Many patients with COVID-19 have low oxygen levels

even when they are feeling well, and low oxygen levels

can be an early warning sign that medical 

intervention is needed."

To help promote student and staff safety during COVID-19, Nonin has created a robust Return to School Guide, which follows recommendation from the American Academy of Pediatrics, the Center for Disease Control and Prevention, and the World Health Organization. 

This resource outlines safe practices for returning to school, as well as additional measures that can help prevent the spread of COVID-19.

Keeping Students and Staff Safe is Your Top Priority

While COVID testing and taking the temperature of all students may not be feasible, schools should identify ways of testing students who are displaying symptoms of COVID-19 or have been in contact with other students who have either displayed symptoms, or have tested positive for COVID-19.1

Along with with checking body temperature, monitoring oxygen saturation (SpO2) can be an effective method for keeping your students and staff healthy, as many patients with COVID-19 have low oxygen levels even when they are feeling well. Low oxygen levels can be an early warning sign that medical intervention is needed.1

What You Need to Know About Pulse Oximeters

How a Pulse Oximeter Works

A finger pulse oximeter functions by shining red and infrared light through your finger. As these beams pass through your digit, the oximeter’s photodetector measures how much red and infrared light is transmitted through it. This process allows the device to assess how heavily saturated your blood is with oxygen, as well as your current pulse rate. Within a few seconds of measurement, these readings are displayed on the oximeter’s screen as a SpO2 percentage and bpm (beats per minute) number.

Using a Finger Pulse Oximeter

Finger pulse oximeters are built with speed and convenience in mind. All you have to do is slide your index finger into the device’s opening until it touches the built-in stop guide. Your oximeter will automatically turn on, complete a brief self-test and begin to measure your oxygen level and pulse rate. Soon after, the oximeter will display your current SpO2 percentage and pulse rate on its screen. Once you’ve finished measuring, you can simply remove your finger and put your oximeter away; the device will automatically shut off within a few seconds.


CM Fingertip Oximeter

The CM personal use fingertip oximeter is an FDA-cleared, hospital-grade device that measures oxygen saturation (SpO2), pulse rate (PR) and low perfusion oxygen saturation (PI). Suitable for home use measurement of oxygen levels.
