Pulse Oximeters

Pulse oximeters, also known as oxygen meters, oxygen readers, oxygen saturation monitors or pulse ox, are small, noninvasive clamp-on devices that tell you what your oxygen saturation level is as well as your heart rate in just seconds. These devices emit light waves that pass painlessly through the body to a photodetector. The light wavelength measurement from its journey through the tissue and blood vessels provides an assessment of blood oxygenation. Chris Cuomo called it one of the most vital items to have on hand if you get Covid, so you can monitor if your oxygen saturation drops below a certain percent. Pulse oximeters most commonly clamp onto one’s finger. Discount Medical sells quality pulse oximeters. Many come with a carrying case, batteries and lanyard. Every person should have one of these.
