Identifying capillary refill time (CRT) is an integral part of the clinical assessment of circulatory status and identification of dehydration in children. However, visual inspection of the finger to assess CRT has low inter-observer reliability, largely due to human limitations in estimating short time intervals. To improve precision, we have developed a mobile phone software application (iRefill) that automatically assesses CRT using a photo-plethysmogram (PPG) sensor. Commonly used to measure blood oxygen saturation and heart rate, this sensor can be adapted to replace the human eye to objectively measure CRT.
