Open neck injuries MOST life-threatening complication is which?

Explanation:
Open neck injuries create a direct pathway for air to enter torn veins, and possibly reach the heart and lungs. Air in the circulation can obstruct blood flow, causing rapid respiratory failure, drop in oxygen levels, and even cardiac arrest. This makes an air embolism the most immediately life-threatening complication, because it can cause sudden collapse long before infection develops or a hematoma expands or nerve damage becomes an issue. Infection, hematoma, and nerve damage are serious concerns, but they tend to evolve over minutes to hours and do not usually produce the same sudden, life-threatening collapse as an air embolism in the acute setting.
