What type of move should be performed to transfer a patient in cardiac arrest to a hard surface?

The appropriate technique for transferring a patient in cardiac arrest to a hard surface is an emergency move. This type of move is specifically designed for situations where immediate action is necessary, such as in the case of a patient without a pulse. In such scenarios, time is critical, and any delay could reduce the chances of a successful resuscitation.

Emergency moves focus on quickly relocating the patient to a location where advanced life support measures can be initiated, like performing CPR or using an automated external defibrillator (AED). In the context of cardiac arrest, the priority is to ensure the patient is on a firm, flat surface to facilitate these life-saving interventions.

The other options typically involve more careful handling or consideration of the patient’s condition. For example, a log roll is generally used for trauma patients who may have a spinal injury, and spinal immobilization is crucial for patients suspected of having spinal injuries, but neither is suited for urgent scenarios requiring immediate deployment of CPR. An assisted carry would be used for patients who can participate to some extent, which is not applicable in a case of cardiac arrest. Thus, an emergency move is the most suitable choice for ensuring a timely response to a life-threatening situation.
