@drjoe_md: It looks alarming, but there's a reason we do it. Briefly placing a child's face in ice water can trigger the diving reflex, which activates the vagus nerve and may slow certain types of dangerously fast heart rhythms. In this case, the child's heart was racing after receiving too much albuterol. Sometimes the strangest-looking treatments are backed by solid physiology. #pediatrics #asthma #parentingtips #emergencymedicine #edutokcontest
