How is capillary refill measured
Web18 jan. 2024 · Background Capillary Refill Time (CRT) is a marker of peripheral perfusion usually performed at fingertip; however, its evaluation at other sites/position may be advantageous. Moreover, arm position during CRT assessment has not been fully standardized.

WebMeasure the capillary refill time (CRT). Apply cutaneous pressure for 5 s on a fingertip held at heart level (or just above) with enough pressure to cause blanching. Time how long it takes for the skin to return to the colour of the surrounding skin after releasing the pressure. The normal value for CRT is usually < 2 s. WebMethods: We used echocardiography to determine cardiac output, and right and left ventricular function in 26 patients (aged 2 weeks to 24 months) with RSV infection. The echocardiographic results were compared with s-troponin, the need for supplementary oxygen or noninvasive respiratory support, and capillary refill time.
WebThe SI unit for surface tension is J/m 2 (or N/m). The accepted value of the surface tension of water in air at 20 o C is γ = 0.073 J/m 2. However, you must use pure water and extremely clean glass to get this result. Usually, the measured surface tension is at least half of this number.
