What this trial studies

This study aims to assess the accuracy of the EvieMED Ring Pulse Oximeter in measuring oxygen saturation levels in healthy volunteers experiencing induced hypoxia. Participants will have multiple pulse oximeters placed on their hands and wrist while their arterial blood oxygen levels are monitored. The study will compare the readings from the test devices to those from established hospital-grade pulse oximeters and arterial blood gas measurements. The goal is to determine how accurately the new device performs in conditions of low oxygen saturation.

Who should consider this trial

Good fit: Ideal candidates for this study are healthy adults without any significant medical history or conditions that could affect oxygen saturation readings.

Not a fit: Patients with obesity, heart or lung diseases, or other serious health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved monitoring of oxygen levels in patients with respiratory issues.

How similar studies have performed: Other studies have shown success in evaluating pulse oximeter accuracy, but this specific approach with the EvieMED device is novel.
