Capillary Refill Time (CRT)

<description>In this episode, Dr. Sergio Zanotti discusses the administration of vasopressor agents through peripheral intravenous lines (or what we refer to as “peripheral vasopressors”). 
He is joined by Dr. Elizabeth Munroe, a practicing pulmonary/critical care physician and an Assistant Professor of Pulmonary and Critical Care at Intermountain Health in Salt Lake City, Utah. Her research interests include evidence-based resuscitation practices in early sepsis and septic shock, vasopressor administration practices, peripheral vasopressor use, and clinical trials, particularly novel, pragmatic clinical trial designs.
