In-Hospital Cardiac Arrest: An Ounce of Prevention Is Worth a Pound of Cure*
Every year, thousands of inpatients unexpectedly die. The prevalence of in-hospital cardiac arrest is around 1.5 per 1,000 hospital admissions, and the survival rate less than 20% (1). Reasons for in-hospital cardiac arrest include, but are not limited to, myocardial infarction, massive pulmonary embolism, tamponade, tension pneumothorax, acute gastro-intestinal or postoperative hemorrhage, severe hypoxemia, and metabolic disorders. Early recognition of the underlying mechanism has significant therapeutic implications and may affect outcome (2).
