OEC Cardiovascular Emergencies & Shock Management Flashcards

What is the correct compression-to-ventilation ratio for single-rescuer adult CPR?

Answer: 30:2

Current AHA guidelines specify a 30:2 compression-to-ventilation ratio for single-rescuer adult CPR to minimize interruptions to compressions.

What is the correct chest compression depth for adult CPR?

Answer: At least 2 inches but no more than 2.4 inches (5–6 cm)

Adult chest compressions should be at least 2 inches deep but no more than 2.4 inches to generate adequate perfusion without causing excessive injury.

What is the recommended chest compression rate per minute for effective adult CPR?

Answer: 100–120 compressions/min

Current guidelines recommend a compression rate of 100–120 per minute to optimize coronary and cerebral perfusion pressure during CPR.

After an AED analyzes the rhythm and advises a shock, what must be done immediately before pressing the shock button?

Answer: Clear all bystanders from contact with the patient

All rescuers must be clear of contact with the patient before pressing the AED shock button to prevent accidental injury from the electrical discharge.

What should be done immediately after the AED delivers a shock?

Answer: Immediately resume CPR starting with chest compressions

Immediately resume CPR starting with chest compressions after AED shock delivery to maintain perfusion without waiting for a pulse check.

Under which circumstances should an OEC Technician stop CPR in the field?

Answer: When authorized medical personnel take over, the patient regains pulse and breathing, or medical direction authorizes cessation

OEC Technicians continue CPR until a higher-level provider assumes care, the patient regains spontaneous pulse and breathing, or medical direction specifically authorizes field termination.
