Popis: Objective: The traditional capillary refill time (CRT) assessment is a manual measurement that is commonly used by clinicians to identify a shock status. Given that the measurement is manual only, it is a relatively subjective measurement. Our study tested an investigational CRT device, comprised of existing pulse oximeter technology paired with a novel measuring algorithm, at an emergency department (ED) setting to determine its reliability and clinical usefulness compared with the traditional, manual CRT assessment. Methods: Three healthcare providers (registered nurses or physician assistants) were selected to perform manual CRT assessments at the bedside to classify patients into either a normal (≤2 seconds) or abnormal (>2 seconds) CRT groups. An attending ED physician, blinded from the healthcare providers’ classifications, quantitatively measured CRT using a chronograph (visual CRT). The pulse oximeter sensor was attached to the same hand used for visual CRT assessments but on a different fingertip. Visual and device CRTs were measured alternately and were repeated three times for each method. Device CRT data from 30 healthy volunteers in a previous study was used as a reference. Results: Thirty ED patients were recruited. Mean device CRT of ED patients (3.9±2.7 sec) was significantly longer than those of healthy volunteers (2.0±1.0 sec, p Conclusions: CRT assessments by healthcare providers were variable compared with those of the ED physician. Device CRT was as reliable and useful as the CRT measured quantitatively by the ED physician.
