CALS / CSU-ALS Latinoamérica
CALS, or Cardiac Surgery Advanced Life Support, and CSU-ALS, Cardiac Surgical Unit Advanced Life Support, describe the training and response framework for cardiac arrest after cardiac surgery. In Latin America, REASEL presents the regional context, distinguishes the international terminology, and guides on available training options. This page does not replace local guidelines nor does it alone define the organization of a clinical team.
CALS stands for Cardiac Surgery Advanced Life Support; CSU-ALS, Cardiac Surgical Unit Advanced Life Support. The international site uses the CSU-ALS name for the Americas. Check regional naming ↗
