This study is testing how accurate the EvieMED Ring Pulse Oximeter is at measuring oxygen levels in your blood, especially when those levels are low (hypoxia). Researchers are comparing its readings to a standard blood test and other hospital-grade pulse oximeters. You might be able to join if you are a healthy adult between 18 and 49 years old, can speak and write in English, and are not obese (BMI over 30). The study aims to see if the EvieMED Ring Pulse Oximeter can accurately measure oxygen levels between 70% and 100%. The current recruitment status is unclear.

Study design

This is an observational study with 12 participants. It is a single-center, single-blinded design, meaning you wouldn't know which specific device is being tested at a given moment.

What's involved

You would have several pulse oximeter devices placed on your fingers and wrist. A small tube (cannula) would be placed in your wrist to draw blood samples. You would breathe different gas mixtures to temporarily lower your oxygen levels over 2 days.

Compensation

Not stated in the trial record.

Follow-up

The primary measurements for oxygen saturation accuracy are taken at 2 days.
