Question #02
What is Photoplethysmography (PPG) used for?
PPG technology has been used as a vital signs monitor in a wide range of commercially available medical devices for measuring oxygen saturation, blood pressure and cardiac output, assessing autonomic function and also detecting peripheral vascular disease.
Question #04
Is my privacy secure?
PPG does not require the capture of your face, fingerprint or other identifiable information. All data used for processing is protected by HIPAA and international security requirements. Generally speaking, it is a very secure vital signs monitor.
Question #01
What is Photoplethysmography (PPG)?
Photoplethysmography (PPG) is a simple and low-cost optical technique that can be used to detect blood volume changes in the microvascular bed of tissue. It is often used non-invasively to make measurements at the skin surface. The PPG waveform comprises a pulsatile (‘AC’) physiological waveform attributed to cardiac synchronous changes in the blood volume with each heart beat, and is superimposed on a slowly varying (‘DC’) baseline with various lower frequency components attributed to respiration, sympathetic nervous system activity and thermoregulation. Essentially, Photoplethysmography makes for a very good vital signs monitor.
Question #03
Is Photoplethysmography (PPG) accurate?
Measurements to the highest degree of accuracy against regulated medical devices. This has been validated in numerous scientific studies, why is makes a great vital signs monitor.
