What compression depth, rate and ratio does Resuscitation Council UK advise for adult basic life support?
Answer and explanation
Correct answer: C. 5 to 6 cm depth, 100 to 120 per minute, 30 compressions to 2 breaths
- Step 1: Adult BLS follows the Resuscitation Council UK algorithm.
- Step 2: The adult standard is 5 to 6 cm, 100 to 120 per minute, and 30:2.
Answer
5 to 6 cm depth, 100 to 120 per minute, 30 compressions to 2 breaths.
Why not the others: 6 to 8 cm depth, 120 to 140 per minute, 30 compressions to 2 breaths in every rescuer: The depth and rate overshoot the recommended range. 4 to 5 cm depth, 80 to 100 per minute, 15 compressions to 2 breaths with two rescuers: The rate and depth are too low, and 15:2 is not the adult ratio. 5 to 6 cm depth, 100 to 120 per minute, 15 compressions to 2 breaths for lay rescuers: 15:2 is a paediatric healthcare-rescuer ratio, not an adult one.
