A rapid response team (RRT) is dispatched to a patient's bedside when their condition begins deteriorating to prevent cardiac arrest or transfer to the intensive care unit. The RRT consists of physicians and nurses who identify at-risk patients based on changing vital signs. Any staff member can activate the RRT if certain criteria are met, such as abnormal heart rate, respiratory rate, blood pressure, or oxygen levels. The implementation of RRTs in hospitals has been shown to reduce code blue events and unnecessary ICU transfers, thereby saving lives and reducing costs compared to allowing patients to deteriorate to a "code blue" state.
