An overnight oximeter is a small device that records your heart rate and oxygen levels throughout the night. This is a continued measurement that graphs your pulse and oxygen blood levels to record information to see if the person’s oxygen level drops through the night. The dropping of oxygen is called a desaturation and can lead to serious health conditions.

We spend a major part of our lives sleeping. Most people sleep for 1/3 of their life! Many of those who have trouble sleeping or feeling well rested may be experiencing similar symptoms to those who have sleep disorders.
