[0002] Emergency critically ill patients are those with severe conditions and unstable vital signs who require immediate emergency treatment and close monitoring. These patients typically face life-threatening conditions, organ dysfunction, or require extensive medical intervention. Generally, critically ill emergency patients are immobile. After being transported to the hospital on a stretcher, they must be transferred from the stretcher to a bed, which is not only troublesome for medical staff but also painful for the patient.
