Show Hint
Air is trapped under pressure; let it out before anything else.

- Needle decompression in the 5th intercostal space in the midaxillary line
- Continue positive pressure ventilation
- Shift to ICU and intubate
- Secure IV line and start fluid resuscitation after insertion of a wide-bore IV line
Show Solution
The Correct Option is A
Solution and Explanation
Read the vitals: Trauma plus hypotension plus respiratory distress plus surgical emphysema plus a silent hemithorax is the textbook quartet of tension pneumothorax. The hypotension tells you this is obstructive shock, not just a breathing problem.
Treat the cause, not the symptom: The patient is dying because air is trapped under pressure and squeezing the great veins. The only fix is to release that air, so any option that does not decompress the chest is wrong by definition.
Walk the options: Continuing positive pressure ventilation actively pumps in more air, the worst possible move. Moving to ICU and intubating delays the one thing that saves the patient. Fluid resuscitation alone treats the low BP number without touching the trapped air. Only needle decompression empties the pleural space.
Procedure note: Insert a wide-bore cannula to decompress, then place a definitive intercostal chest drain. The classic site is the 2nd space midclavicular line, while modern ATLS allows the 5th space in the anterior or mid-axillary line, which is the site quoted in the answer here.
