Final answer:
If positive pressure ventilation does not result in a rising heart rate or bilateral breath sounds or chest movement, a chest tube or needle decompression may need to be inserted.
Step-by-step explanation:
If, after performing the ventilation corrective sequence and making appropriate adjustments, you are unable to obtain a rising heart rate or bilateral breath sounds or see chest movement with positive pressure ventilation, you usually will have to insert a chest tube or a needle decompression.
