Is the statement 'A sucking chest wound left untreated will only lead to excessive blood loss' true or false?

• A. False
• B. True
• C. It can also cause air embolism
• D. It is life-threatening in other ways

Answer: (A)

The main idea is that a sucking chest wound is dangerous for more than just blood loss. When the chest is open, air is drawn into the pleural space with each breath, which can cause a pneumothorax and, if air accumulates under pressure, a tension pneumothorax that shifts the heart and great vessels and seriously impairs breathing and circulation. There’s also a risk that air can enter the bloodstream and cause an air embolism. Because of these serious alternatives to bleeding alone, the statement is false. In first aid terms, seal the wound with an airtight dressing to limit air entry, monitor breathing, and seek urgent medical help.
