Description

<p>We investigated the influence of photoplethysmogram (PPG) to the finger contact pressure, on indices derived from the acceleration PPG (APPG) believed to reflect arterial aging using a smartphone photoplethysmograthy. The first and second peak amplitudes in the APPG, 'a' and 'b' respectively, were measured using an iPhone 7 in 12 participants and the 'b/a' ratios for 4 conditions (i.e., relaxed, normal, little strengthened, and strengthen take hold the iPhone 7) were derived. Results indicate that the b/a ratio of 3 condition (i.e., relaxed, normal, little strengthened) were not significantly different except for 'strengthen'. In conclusion, these findings suggest that use of b/a iPhone photoplethysmography, if the range of normal contact pressure, might be practical measurement when assessing arterial aging.</p>
