This information is outdated, wrong, and DANGEROUS.
Lifting the legs (aka shock position) has no effect and has been taken out of most first-aid guidelines for a reason.
The post also mentions "60 times a minute" when doing CPR. This is WAY to slow. Ideally you should push down 100-120 times a minute. If you do it 60 times a minutes you will not be able to generate enough blood pressure and the blood will not circulate - which is the goal of CPR.
The most important things you can do for someone during a cardiac arrest is: - Call 911 / call for help - Do CPR - If there is an AED nearby - get someone to fetch it, turn it on and follow instructions
For the love of god, do not just stand there with the legs in the air.
