Q: In the event of a casualty requiring chest compressions, what is the ratio for chest compressions to rescue breaths?
A: 15 & 2
B: 30 & 2
C: 25 & 2
D: 30 & 0
Wrong answer. You answered A but B and D are the correct answers.
It's a bit naughty of us to throw in a trick question but it's a hot topic and we like to promote debate and conversation.
If the casualty is unconscious and not breathing it is better to perform chest compressions than not. This will keep the (already oxygenated) blood pumping around the casualty and help keep them alive. There is no need for rescue breaths. So the ratio would be 30 & 0. However if you feel able to perform rescue breaths then the ratio is 30 & 2.
From the First Aid Manual,10th edition.
“Healthcare professionals and trained first aiders will deliver CardioPulmonary Resuscitation (“CPR”) using chest compressions combined with rescue breaths. However, if you have not had training in CPR or you are unwilling or unable to give rescue breaths, chest-compression-only CPR has been shown to be of great benefit certainly in the first minutes after the heart has stopped.”
