#208 Lactate and Capillary Refill Time | Comprehensive Overview Perfusion Assessment in Shock (ED/ICU)
Assessing tissue perfusion is central to managing shock and critical illness. In this comprehensive episode, we review lactate, capillary refill time (CRT), and then directly compare the two bedside perfusion markers, focusing on how to interpret them in emergency and critical care settings. We cover: • Lactate physiology and causes of elevation • Type A vs Type B lactic acidosis • Prognostic value of lactate in critical illness • Capillary refill time physiology and measurement • Normal vs abnormal CRT values • CRT in septic and non-septic shock • Strengths and limitations of lactate vs CRT…
