An emergency trolley, often referred to as a crash cart, is typically stocked with a range of items crucial for advanced cardiac life support (ACLS) and other life-saving procedures. Common contents include defibrillators, airway management tools such as endotracheal tubes and bag-valve masks, intravenous (IV) supplies, various medications like epinephrine and atropine, and basic first aid equipment. Each item is meticulously organized, often color-coded, to allow for quick access in high-pressure scenarios.
