Abstract
The COVID-19 pandemic has posed significant challenges to healthcare
systems worldwide, with critically ill patients requiring intensive care and
fluid management to maintain systemic hemodynamics. This study aimed to investigate
the potential of remote photoplethysmography (rPPG) and automated capillary
refill time (aCRT) techniques for assessing alterations in peripheral perfusion
among patients with severe COVID-19 infection during fluid resuscitation. Eight
patients with severe acute respiratory distress syndrome (ARDS) due to COVID-
19 were enrolled in a single-center prospective pilot study. Fluid responsiveness
was evaluated using the passive leg raising test (PLRT) and a fluid challenge.
Hemodynamic variables, perfusion index (PI) detected by rPPG, and manual and
automated CRT parameters were collected at four different time intervals during
the test. The results showed significant changes in hemodynamic variables, rPPG
perfusion index, and manual and automated CRT parameters during fluid resuscitation,
suggesting that these techniques could accurately evaluate peripheral perfusion
changes in critically ill COVID-19 patients. The automated CRT technique,
which provided objective assessments of capillary refill time, was found to be a
potential alternative to the manualCRT technique. The present pilot study supports
the hypothesis that rPPG and aCRT techniques, in conjunction with hemodynamic
parameters, can reflect changes in peripheral perfusion during fluid resuscitation
in patients with severe COVID-19. However, further studies with larger patient
populations are required to validate these findings and develop guidelines for the
application of these techniques in clinical practice.
