Follow the BLS algorithm of scene safety, checking for response, calling for help, checking pulse and breathing simultaneously. IF you have not read single rescuer BLS already, go through it once to know these steps properly.
Having an extra hand is useful during resuscitation.
If the victim is not having a pulse and not breathing or only gasping, treat it as cardiac arrest and ask EMS (Emergency medical service) for an AED (Call 112 in India Or send someone to bring it if it’s near by).
First rescuer should start chest compressions as described before. Click here to review the technique.
Second rescuer will stay at the head end giving 2 breaths every 30 compressions. Click here to review the technique.
Such 30 compressions to 2 breaths should be continued for 5 cycles (Roughly 2 minutes) or whenever the 1st rescuer is tired of giving compressions.
At 2 minutes (5 cycles of CPR)
At the end of 5 cycles of CPR / 2 minutes, check pulse.
If still there’s no pulse, you may switch roles and continue CPR till advanced help arrives (EMS).
First rescuer should go to the head end and Second rescuer should come for compressions.
This switch should occur fast and rescuers should not cross-over.
The rescuer at the head end will go to the free side of Victim, not to the side of first rescuer.
