So help me, I worked as a lifeguard this summer and my manager comes in one day and asks me how I would perform cpr on a giraffe and showed me this image.
It was posted on the wall of our break room. Nobody could provide a solid answer.
If they choked on something, I doubt they have enough space in their lungs to force it out. Clearing the obstructed airway should be the priority first perhaps by running your hands along the neck, then chest compressions to restart the heart and get blood moving oxygen around.
last time (~ half year ago) they thaught me this they said chest compression is more than enough. there should be enough oxygen in the lungs and blood till professional help arrives, and as you said most of the time airway is blocked in these situations
also most people are extremely unconfortable to blow air through someones nose/mouth, so it incrreases the number of people that are willing to help
Just fyi, chest compressions cannot restart a heart, they can keep blood flowing until an AKG can get it into a normal heartbeat. If the heart is completely stopped, neither compressions or an AKG can do anything.
Adding yet another PSA to these comments that it is no longer recommended to pause chest compressions while doing cpr. You should exclusively be doing chest compressions until professional help arrives.
Adding a PSA to state that you shouldn't take medical advice from random people on the Internet.
If you are trained in CPR, follow your training. If your certification has expired you should re-up it. There are legal reasons some training says certain things in different areas and following your training will protect you even if you go to a place with different laws.
