About

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.

Full description

The huge impact of the COVID-19 pandemic on global healthcare systems has given rise to an increased need for virtual care. This pilot study will determine the feasibility and effectiveness of implementing video plethysmography (PPG)for contactless vital signs measurements such as blood pressure (BP), heartrate (HR), respiratory rate (RR) and heart rate variability (HRV) from surgical patients in preoperative care. We also aim to validate the use of video PPG in measuring HRV and stress index when compared to a validated stress questionnaire.

This study aims to assess how video PPG technology can be implemented in a clinical and telemedicine. If proven to be effective, this technology can be integrated into any smartphone or tablet and will allow users to monitor their vital signs with just a 1.5-minute video.

Contactless vital signs and stress measurement.

Description:

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.
