Several rescuers respond and you ask them to activate the emergency response system and retrieve the AED. As you check for as pulse and breathing you notice that the man is gasping for air and making snorting sounds. You do not feel a pulse.
What is your next best action?
Start high quality CPR beginning with chest compressions
What is the ratio of chest compressions to breaths when providing CPR to an adult?
30:2
What are the rate and depth for chest compressions on an adult?
100-120 cpm and a depth of at least 5cm
A 53yo man collapses and becomes unresponsive. You witness his collapse and are the first rescuer at the scene where the man is lying motionless on the floor.
What action should you take when more rescuers arrive?
Assign tasks to other rescuers and rotate compressors every 2min or more frequently if needed to avoid fatigue
