They should provide breaths for the infant every 5 seconds.
You should stand back as the AED analyzes the patient.
Switch when the person giving compressions is getting tired.
Since 2005 the American Heart Association has recommended that bystanders trained in CPR should NOT be checking a pulse. If an unresponsive patient is not breathing rescuers should start compressions. Professional rescuers like paramedics, nurses, and doctors still check a pulse. Pulse checks should never last longer than 10 seconds. For more information you should take an American Heart Association CPR class form a reputable company like The Heart Center.
Do not stop CPR to check for a pulse.
With 2 rescuers, compressions and ventilations should be done at a ratio of 15:2 for an infant or child.
30:2
Some AEDs after the pads are attached you plug in the pads before the AED will analyze; some the pads are attached to the AED and you need to push the analyze button. At this point, do not touch the patient. So, the best answer to me is "the rescuers should make sure the AED is analyzing and do not touch the patient".
Do not stop CPR to check for signs of life in Adult CPR. Continue CPR until help (EMS) arrives or someone takes over.
Do a pulse check about every 2 minutes (or after 5 cycles of CPR).
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.
30 compressions to 2 breaths for one rescuer and 15 compressions to 2 breaths for 2 rescuers (also use the two hands encircling thumbs position for 2 rescuers). The old compression ratio was 5 compressions to 1 breath.
