A crash cart is a cart that has all the emergency equipment and medicine emergency medical professionals need to attempt to save the life of a person who's not breathing or is in a life threatening cardiac rhythm. Usually the cart is compiled of a tool cart. The cart is on wheels so it can be transported to different areas where an emergency will be. It's generally available in case a patient goes into respiratory or cardiopulmonary arrest (heart and breathing stop), or for emergencies often referred to as codes or code blues. Yet the cart is also used to treat impending or active symptoms that could lead to more serious complications if not treated immediately, such as new onset symptomatic supraventricular tachycardia. It's also carted to the bedside of patients who don't look quite right, and in this case a rapid response team is called. The goal here is to avert an impending emergency situation by treating early signs and symptoms of failure, such as mental changes, vital sign changes, and erratic heart rhythms.
