6. Adult Two-Rescuer CPR

Question 1

What are the two scenarios for initiating two-rescuer CPR?

Answer 1

1) Two rescuers found a collapsed casualty and initiate CPR immediately
2) A rescuer performs CPR first followed by the entry of a second rescuer

The presence of a second rescuer allows for activation of EMS and reduces fatigue.

Question 2

What should the second rescuer do upon arrival at the scene?

Answer 2

Activate EMS if not already done

This ensures emergency services are alerted while CPR is in progress.

Question 3

What is the recommended chest compression to ventilation ratio for infants and children ≤ 12 years?

Answer 3

15:2

This ratio is specific to the age group for effective CPR.

Question 4

What is the recommended chest compression to ventilation ratio for adults and adolescents > 12 years?

Answer 4

30:2

This ratio is standard for adults and adolescents during CPR.

Question 5

What should the second rescuer say upon entering to assist with CPR?

Answer 5

“I know 2-man CPR, can I help?”

This helps establish communication and confirm the willingness to assist.

Question 6

What is the first action of Rescuer 1 after Rescuer 2 offers to help?

Answer 6

Complete the cycle of 30 chest compressions followed by 2 ventilations

This ensures continuity in CPR while transitioning roles.

Question 7

What role does Rescuer 1 take after Rescuer 2 arrives?

Answer 7

Ventilator role

Rescuer 1 assesses for circulation and provides ventilations.

Question 8

What should Rescuer 2 do upon entering the scene?

Answer 8

Take on the role of the compressor

Rescuer 2 locates the landmark for chest compressions while Rescuer 1 assesses for pulse.

Question 9

How often should rescuers change roles during CPR to minimize fatigue?

Answer 9

Every 2 minutes, approximately 5 cycles of 30:2

This helps maintain the effectiveness of chest compressions.

Question 10

What must be checked before commencing two rescuers CPR or after any changeover of roles?

Answer 10

Pulse check

This ensures that CPR is necessary and effective.

Question 11

What should be done if no pulse is detected after a changeover?

Answer 11

Start a new cycle of CPR

This indicates the need for immediate re-initiation of life-saving measures.

Question 12

What is the recommended rate for chest compressions if mouth-to-mouth ventilations are not possible?

Answer 12

100-120 compressions per minute

Continuous chest compressions are crucial for maintaining blood circulation.

Question 13

How long may a rescuer rest after 100 chest compressions if fatigue sets in?

Answer 13

Not more than 10 seconds

Short rest intervals help maintain the quality of CPR.
