Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This study designed is compare the pulse response to the Valsalva maneuver between a photoplethysmography sensor (PPG) and non-invasive blood pressure sensor for the purpose of validating the PPG methodology in deriving a value for the Valsalva pulse response. The aim is to show that the PPG method captures the same phase responses as the blood pressure monitor and the primary outcome is the correlation between pulse amplitude ratios for the pulse at the end of the Valsalva to an average baseline pulse.
