Final answer:
When a PCT is faced with an unresponsive patient and lacks the necessary equipment, they should perform CPR without protection.
Step-by-step explanation:
CPR stands for cardiopulmonary resuscitation, and it is a life-saving technique used to maintain the flow of blood in an unresponsive patient until medical assistance arrives. In this situation, without a face shield or AED, the PCT should perform CPR without protection.
The technique involves applying pressure with the flat portion of one hand on the sternum between the lines at T4 and T9. The PCT should compress the chest at least 5 cm deep and at a rate of 100 compressions per minute.
Performing CPR is crucial in maintaining the blood flow and increasing the chances of survival for the patient.
