SpO2 Comparison Between Commercial Smartwatch and Medical-grade Pulse Oximeter During Hypoxia

NCT05657288 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40

Last updated 2023-03-17

No results posted yet for this study

Summary

The aim of the project is to experimentally compare SpO2 measured on a wrist by commercial Smartwach and on a finger measured by a medical-grade pulse oximeter in healthy humans during gradual desaturation in the range of 60-100% SpO2 and simultaneously during a step change from the hypoxic phase to the recovery phase (return to physiological values).

Conditions

Interventions

OTHER

Breathing mixtures of O2 and N2 and monitoring SpO2 on finger and left wrist

Volunteers sequentially inhale three hypoxic gas mixtures each for 2.5 minute. Every measurement will begin with a two-minute stabilization phase, during which the physiological values of the volunteer will be checked. During the whole experiment, non-invasive SpO2 measurements will be performed on the middle finger and on the wrist of left hand.
