SpO2 Difference Between Fingers of the Hand During Sequential Desaturation and Step Resaturation
NCT05681637 · Status: UNKNOWN · Phase: NA · Type: INTERVENTIONAL · Enrollment: 40
Last updated 2023-03-17
Summary
The aim of the project is to experimentally compare the fingers of the hand in terms of measured concentrations of peripheral blood oxygen saturation (SpO2) 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
- Hypoxia
- Pulse Oximetry
- SpO2
Interventions
- OTHER
-
Breathing mixtures of O2 and N2 and monitoring SpO2 on each finger
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 experiment, non-invasive SpO2 measurements will be performed continuously on the individual fingers of volunteer hands throughout the experiment.
