What are the requirements for CPR? Do I have to get on my knees to perform it?

CPR course requirements and kneeling positions for practical assessment.

Yes, you do. You need to demonstrate a 2-minute continuous period of performing CPR on an adult manikin which must be placed on the floor (same with child manikin for those doing HLTAID012). CPR on infant manikins needs to be performed for 2 minutes on a firm surface.
