Pulse Oximeter Accuracy During Stable Hypoxia Plateaus

NCT07408388 · Status: ACTIVE_NOT_RECRUITING · Type: OBSERVATIONAL · Enrollment: 48

No results posted yet for this study

Summary

The aim of this study is to determine the accuracy of devices called pulse oximeters, which measure blood oxygen by shining light through fingers, ears or other skin, without requiring blood sampling. Study will be used with healthy volunteers at rest.

Conditions

Interventions

DEVICE

Pulse Oximeter

OLV-4202 pulse oximeter ((SW version: 01-17)

PROCEDURE

Induced hypoxia through breathing nitrogen-air-carbon dioxide mixture

Subjects will be placed in a seated semi-reclined position. Subjects will breathe a nitrogen-air-carbon dioxide mixture to produce the desired level of hypoxemia. Stable, safe and controlled hypoxia is obtained by breath-by-breath analysis of respiratory gas using a gas analyzer that permits the inspired gas mixture to be adjusted to achieve the desired degree of blood oxygen saturation. Study is observational to see response of pulse oximeter. Intervention (above) is not therapeutic, rather is simply used to vary oxygen levels in subjects.
