Help already should have been called, so you continue CPR until EMS arrives, the patient shows signs of life, or you are too exhausted to continue.
Yes; you should still do CPR.
Open the airway and check for breathing (signs of life; look, listen & feel); if not breathing give two breaths then start CPR.
1 cycle is the compressions and breaths combined.
A CPR cycle is 30 compressions and 2 breaths, to be performed in 24 seconds.
no pulse. check airway, check breathing, check circulation. begin CPR.
CPR consists of 30 compressions and 2 breaths, per cycle. CPR is a process to circulate oxygenated blood throughout the body.
5 cycles of CPR means repeat the 30 compressions and 2 breaths 5 times.
30 compressions and 2 rescue breaths
If after the head is tipped for 10s, and there is no breathing (adult), give 2 breaths and immediately begin CPR.
It used to be that after every 2 minutes of CPR, you did a pulse check. Now, once it is confirmed there are no signs of life, CPR is not stopped until EMS arrives and takes over. When EMS arrives, they will do a pulse check (which includes a breathing check) and if no pulse the AED will be hooked up. Since for the lay rescuer the rescue breathing (RB) for adults has been eliminated, there is no check required as CPR is immediately started. For children and infants, where RB is performed, after every 2 minutes you do a pulse check.
