Does an optimized algorithm for imaging photoplethysmography improve the accuracy of pulse-transit-time measurement in healthy volunteers?
An optimized algorithm for imaging photoplethysmography improves the accuracy of pulse wave parameter measurements, offering a potential noncontact method to assess microcirculation.
No takes yet. Share an insight, caveat, or question.
May reduce PTT variability in volunteers; leaves open clinical utility for noncontact microcirculation assessment.
Kamshilin et al. (2016) conducted an observational in Healthy volunteers (n=36). Advanced algorithm for IPPG data processing vs. Direct application of the minimal-value method was evaluated on Standard deviation of the mean pulse transit time (PTT). An advanced algorithm for imaging photoplethysmography data processing decreased the standard deviation of pulse transit time measurements by an average of 2.3 times compared to the standard minimal-value method.
