Whether You Use the Mouth-To-Barrier or the Mouth-To-Mouth Procedure,when Administering

Whether you use the mouth-to-barrier or the mouth-to-mouth procedure,when administering CPR to the adult or child,the personal care provider should:

A) reposition the client's head and give the person a second breath if the chest does not rise and fall after the fourth breath
B) use the strength of your cheeks to deliver a forceful puff of air into an infant
C) give a second breath before the chest begins to deflate
D) allow the chest to deflate after the second breath before doing compressions again
