Related: Fall prevention
Choking

A blocked airway caused by food or an object, shown by the inability to speak, cough, or breathe. The aide calls for help and begins trained rescue steps right away.

Related: Dysphagia, Aspiration
CPR

Chest compressions and rescue breaths given when a person's heart or breathing has stopped, continued until a nurse, the emergency team, or an automated defibrillator takes over.

Intake and output

A record of all fluid a resident drinks and all urine, vomit, or drainage produced, usually measured in milliliters, used to judge whether the body's fluids are balanced.
