Question 15

During CPR, adults should be ventilated at a rate of (1.) —.

Answer 15

1. one breath every six seconds

10 breaths per minute

Question 16

1. During attempted CPR, is it best to place an iGel before or after the BVM, oxygen, viral filter and ETCO₂ have been prepared?

Answer 16

1. Before

Some ventilation will occur through the iGel alone during compressions.

Answer 18

1. Gastric suction tube
2. Tracheal suction tube
3. Ducanto hard suction catheter
