old way five compression one full breath, new way five compression every 1o senconds
1 cycle is the compressions and breaths combined.
When two rescuers are preforming CPR on a child, the compression to breath ratio is 15:2. That is 15 compressions 1-1.5" deep at a rate of 100 compressions a min. Each rescue breath should last about one second and make the chest clearly rise. The cycle is then repeated, fifteen compressions and two breaths. The rescuers should change positions about every 2min or about 10 cycles.
It only takes 1 person to perform CPR. An advanced CPR course can be taken to train you on 2-person CPR, which makes it easier and more productive than 1 person CPR.
If the child has stopped breathing and has no pulse American Heart Association CPR states 30 compressions for every 2 breaths for a child ages 1 years of age to Puberty. If the child has stopped breathing, you want to make sure that there is no pulse before starting CPR. If a pulse is still present, check to see if there are any visible airway obstructions first (toys, foreign objects), if so safely remove object, do not blindly stick finger down child throat, if not give assisted ventilations.
Perform Adult CPR by 30 chest compressions to 2 breaths.
In the world, about 1 in every 50 teens knows CPR.
1 min = 60 sec Hence 1 sec = 1/60 min
Each compression of the heart during CPR will pump approximately the same amount of blood during a normal beat. This amount of blood, per the related link, is 2.4 ounces (70milliliters) per beat.
98 minutes
1 min = 60 sec 30 min = 1800 sec
there are 4,920 seconds in 1 hour 22 min.
1 hr = 60 min ⇒ 1 hr 13 min = 1 x 60 + 13 min = 73 min 13 miles in 73 min → 1 mile in 73 ÷ 13 min = 58/13 min/mile ≈ 5.62 min/mile
