Continue chest compressions

18
Q

What should you do while the AED is about to shock the patient?

A

19
Q

How many joules / volts is in one AED shock?

A

It’s a 2 person technique where one person holds the mask to the patient’s face from behind ensuring head tilt chin lift. The other person operates the bag.

22
Q

26
Q

How often should oxygen cylinders be checked?

A

Daily

27
Q

What are OPA?

A

28
Q

How to insert an oropharyngeal airway

A

insert upside down, twist 180 degrees, insert

29
Q

What does post resuscitation care involve?
