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.
