Brief Summary

This pilot study will determine the feasibility and effectiveness of implementing video plethysmography (PPG) for contactless vital signs and str5ess index measurements from surgical patients in preoperative care. Our primary objective is to determine the feasibility and validity of using video PPG to collect contactless BP, HR and RR measurements when compared medical-grade instruments. Our secondary objective is to validate the use of video PPG in measuring HRV and stress index when compared to a validated stress questionnaire.

Study Arms (1)

Contactless vital signs and stress measurement.

Contactless vital signs and stress measurement. Eligible participants will agree to have a 1.5-minute facial video recorded using an iPad. Video will be processed through a specialized algorithm to obtain BP, HR, RR, HRV and stress index. measurements.

Device: Video PPG

Interventions

Video PPG DEVICE

Contactless vital signs and stress measurement using video PPG technology. An iPad will be used to record a video of the participant's, which can then be converted to vital signs using a specialized algorithm.
