Capilary Refill time in child with shock is ?

1. Capillary refill time (C) * The accepted upper normal time is < 3 sec. * A study of 469 preterm and term healthy neonates at 1-7 days of age demonstrated significant site and observer variations when C was measured on the chest, forehead, palm, and heel. * C is more reliable when measured on the chest but not the forehead, palm or heel. A positive predictive value of C for SBF was found only when the refill time was over 6 s. When the refill time is this long, the clinician generally does not need to press the skin to know that something is wrong. Press on the finger for five seconds using moderate pressure at an ambient temperature of 20-25 degrees Celsius. A capillary refill time of three seconds or more should be considered abnormal. ... Normal capillary refill time is usually 2 seconds or less. Reference: GHAI Essential pediatrics, 8th edition
