Based on

1sec= duration of giving one rescue breath (blowing air into the victim’s mouth)

5-10sec.• Check pulse for

– not less than 5 sec– not more than 10 sec

NW26072014

18sec.= duration of one cycle of 30 chest compressions @100/min

(60sec/100 = 0.6 sec) x 30 = 18 sec

NW26072014

2min.= Duration of 5 cycles of 30 chest compressions @100/min: 2 rescue breaths

1 cycle of 30:2 = Chest compressions:[(60sec/100 = 0.6 sec) x 30 = 18 sec] + [2 rescue breaths: 2 sec. blowing in + 2 sec. for letting air come out = 4 sec] +[time for moving between chest and mouth = 2 sec] = 24 sec 5 cycles of 30:2 = 24 sec x 5 = 120 sec = 2 min

•Then check pulse to see if circulation has returned

2min.• Duration of 1 cycle of rescue breaths

10-12 breaths/min - adults

12-20 breaths/min - children/infants

• Then check pulse to see if circulation is still present
