Reimagining Resuscitation Physiology: How Nebulized Nitroglycerin Augments Carotid Flow in Cardiac Arrest

What if improving survival from cardiac arrest wasn’t just about pushing harder - but perfusing smarter? Emerging research demonstrates that nebulized nitroglycerin may significantly increase carotid blood flow during CPR - potentially doubling cerebral perfusion without compromising coronary or systemic pressures. This session explores the physiology behind pulmonary vascular resistance, the limitations of current resuscitation strategies, and how a simple, prehospital-ready intervention could redefine how we think about brain-directed resuscitation.
