e. Continue to monitor the casualty's breathing.
(1) If the casualty's breathing rate falls below two breaths every 15 seconds,
insert a nasopharyngeal airway (Lesson 3).
(2) If tension pneumothorax develops, perform a needle chest
decompression (Lesson 4).

(3) The casualty does not have vital (life) signs; that is, the casualty is not

(4) The casualty's injury is probably not survivable given the battlefield

(a) Penetrating head injuries with brain tissue exposed.
(b) Severe burns covering a large part of the body.
Mutilating blast injuries.
