DiCARTTM device to measure capillary refill time: a validation study in patients with acute circulatory failure
Authors' conclusion
The DiCART™ device showed poor agreement with clinical CRT in patients with acute circulatory failure
Study context
- Population
- Patients with acute circulatory failure; Capillary Refill Time (CRT) measured on fingertip, chest and knee
- Participants
- 25 patients
- Comparison
- Automated DiCART™ CRT vs clinically measured CRT
- Outcome
- Agreement between CRTDiCART and CRTCLIN (ICC and Bland and Altman analysis)
Methodological detailscomparative interventional study, single-centre, blinded operators, Three measurements per site averaged; clinical and DiCART™ measurements by two different operators, each blinded to the results
- Comparative interventional study
- Single-centre
- Blinded operators
- Three measurements per site averaged; clinical and DiCART™ measurements by two different operators, each blinded to the results
