DiCART device to measure capillary refill time: a validation study in patients with acute circulatory failure.
J Clin Monit Comput
February 2025
Service d'anesthésie-réanimation, Hôpital cardiologique Louis Pradel, Hospices Civils de Lyon, Bron, France.
Capillary Refill Time (CRT) is a valuable metric to assess cutaneous perfusion. Its prognostic value in patients with acute circulatory failure has been reported as improved when the measurement is standardized. The DiCART™ device is a fully automated CRT measurement tool requiring validation.

Background: Capillary refill time (CRT) and skin blood flow (SBF) have been reported to be strong predictors of mortality in critically ill patients. However, the relationship between both parameters remains unclear.
Methods: We conducted a prospective observational study in a tertiary teaching hospital.

(1) Background: To develop a novel capillary refill time measurement system and evaluate its reliability and reproducibility. (2) Methods: Firstly, the utilization of electromagnetic pressure technology facilitates the automatic compression and instantaneous release of the finger. Secondly, the employment of pressure sensing technology and photoelectric volumetric pulse wave analysis technology enables the dynamic monitoring of blood flow in distal tissues.

Emergency Medical Service Vienna, Vienna, Austria.
Introduction: Microcirculatory alterations are predictive of poor outcomes in patients with shock and after cardiac arrest in animal models. However, microcirculatory alterations during human cardiac arrest have not yet been studied.
Methods: We prospectively included adult patients receiving resuscitation after witnessed out-of-hospital cardiac arrest.

The monitoring of peripheral circulation, as indicated by the capillary refill time, is a sensitive and accurate method of assessing the microcirculatory status of the body. It is a widely used tool for the evaluation of critically ill patients, the guidance of therapeutic interventions, and the assessment of prognosis. In recent years, there has been a growing emphasis on microcirculation monitoring which has led to an increased focus on capillary refill time.
