Bathroom Entrapment Leading to Cardiac Arrest From Crush Syndrome
Abstract:
Crush injuries have the potential to cause life-threatening systemic effects such as hyperkalemia, dysrhythmias, acute kidney injury, and renal failure. Systemic involvement is known as crush syndrome (CS) and results from tissue ischemia and muscle necrosis. This is a report of a 76-year-old female who developed a fatal dysrhythmia following release of her extremity from prolonged entrapment in bathroom safety equipment. Hyperkalemia should be presumed in any crush injury and be treated empirically and aggressively. Although tourniquet application prior to extrication is not widely recommended to prevent CS, it should be considered in prolonged extremity entrapment.

Cardiac Output I:Effect of Heart Rate on Cardiac Output
Cardiac output (CO) refers to the total amount of blood ejected by one of the ventricles in liters per minute (L/min). In a resting adult, CO ranges from 5 to 6 L/min, adjusting according to the body's metabolic requirements.
Effect of Heart Rate on Cardiac Output
Cardiac output adapts to metabolic demands during stress, physical activity, or illness. The autonomic nervous system regulates heart rate via the sinoatrial node. The parasympathetic nervous system decreases heart...
