رجل عمره ٣٣ سنة وصل بعد طعنة في يمين الصدر، والجرح يصدر صوت مص مع كل شهيق، وتخرج فقاعات دم منه. ضيق نفس، والتنفس ٣٠، والتشبع ٩٠٪. ما أول إجراء إسعافي؟

A 33-year-old man arrives after a stab wound to the right chest. The wound makes a sucking sound with each breath and bloody bubbles emerge. He is breathless; RR 30, SpO2 90%. What is the first emergency action?

1. A three-sided or vented chest seal dressing
2. A fully occlusive four-sided dressing without monitoring
3. Leaving the wound uncovered until the surgeon comes
4. Packing the wound tightly with gauze to close it

Answer: A) A three-sided or vented chest seal dressing. A sucking chest wound is an open pneumothorax. A vented or three-sided dressing stops air entering while allowing it out. Complete sealing can create a tension pneumothorax, so the client is watched closely.
