Comparison of a Non Contact Vital Signs Application With Traditional Pulse Oximetry for Heart Rate Measurement

Not Applicable

Completed

• Conditions: Heart
• Interventions: Device: Pulse oxymetry; Device: Darwin smartphone app

• Registration Number: NCT06439511
• Lead Sponsor: Hôpital du Valais

Brief Summary

The investigators want to test the accuracy of the Smartphone application Darwin Edge rVSM in measuring heart rate, as compared to traditional pulsoxymetry. The intervention is to look at the smartphone camera for approximately 30 seconds, and after that to compare the heart rate value with that obtained with a recording by pulsoxymetry.

Detailed Description

Participants undergoing a routine perianesthetic consultation at the preanesthetic clinic will be recruited. as a part of routine clinical assessment their heart rate is measured with pulsoxymetry, a non invasive device worn at the fingertip for about 1 minute. this measurement will be compared to the values for heart rate that can be obtaine with the ''Darwin Edge rVSM'' mobile application. this application can be installed on any smartphone. the participant is required to look into the smartphone camera for about 30 seconds. environmental and lighning conditions will be kept stable.

The investigators will do the measurements in 200 participants in order to obtaine values in a population characterized by a variety of phenotypes, in the perioperative setting.
