The reliability of the results of self monitoring of the vitals in the wild
using medical devices or wearables or camera based smart phone solutions is
subject to variabilities such as position of placement, hardware of the device
and environmental factors. In this first of its kind study, we demonstrate that
this variability in self monitoring of Blood Pressure (BP), Blood oxygen
saturation level (SpO2) and Heart rate (HR) is statistically significant
(p<0.05) on 203 healthy subjects by quantifying positional and hardware
variability. We also establish the existence of this variability in camera
based solutions for self-monitoring of vitals in smart phones and thus prove
that the use of camera based smart phone solutions is similar to the use of
medical devices or wearables for self-monitoring in the wild.
