The resident rattles off '아이브이' — the Korean pronunciation of 'IV', meaning intravenous. Korean medical teams freely mix English medical abbreviations spoken in Korean phonetics with native Korean terms, so you'll hear things like 'IV 처방' (prescribe IV) right alongside Korean words mid-procedure.
과장 (gwajang) literally means 'section chief' and in a hospital it refers to the head of an entire clinical department — a senior attending role with budget responsibility and a seat at formal meetings. Yangjaewon is being reminded that Baek Ganghyeok now technically holds that title for trauma surgery, even if only temporarily.
300억 (sam-baek eok) is 30 billion Korean won — roughly 22 million USD. Korean hospitals, including university teaching hospitals, operate as commercial entities and track profit and loss closely. Hitting a 30-billion-won surplus is treated here as a landmark achievement worth applause in a formal department-head meeting.
Large Korean hospitals commonly operate their own 장례식장 (jangnye sikjang), or funeral hall, on the premises. Because demand is steady and overhead is low, these facilities are notoriously among the most profitable parts of a hospital complex — a dark running joke in Korean medical culture that the show leans into here.
감마나이프 (Gamma Knife) is a brand of radiosurgery equipment used for precise, non-invasive brain treatments. 명의 (myeong-ui) means 'renowned physician' or 'master doctor' — a title that carries enormous weight in Korea, where celebrity doctors attract patients from across the country and can single-handedly spike a department's revenue.
Baek uses the expression '꿀 빨다' — literally 'to suck honey' — which is common Korean slang meaning to enjoy easy benefits or free-ride on someone else's work. He's accusing the other departments of profiting from trauma cases while leaving the financial losses to his unit.
'근본 없는 쌍놈' is a sharp traditional insult meaning roughly 'a lowborn wretch with no roots or breeding.' 쌍놈originally referred to the lowest class in Korea's Joseon-era social hierarchy. Throwing it at someone in a professional meeting is an extreme breach of decorum — which is exactly why the room erupts.
Baek patches the torn heart wall using a sterile surgical glove as a temporary reinforcement — a real field-expedient method documented in trauma literature when standard repair material isn't immediately viable. The glove buys a few minutes of hemostasis while a permanent fix is prepared, which is why he has Residents count down the window.
Baek calls for an 이비인후과 (ENT department) nasal endoscope — a slim camera normally used for nose and throat procedures — to navigate inside the heart and retrieve the glove fragment. Using instruments wildly outside their intended specialty is a hallmark of damage-control surgery in under-resourced or emergency settings.
블랙윙즈 (Black Wings) is described as a top-tier private military company (PMC) — a for-profit firm that provides armed personnel and tactical services in conflict zones. PMCs operate in legal grey areas internationally and are controversial because their contractors can engage in combat outside the chain of military accountability.
