noun
emergency room; ER
Medical term for the hospital department that provides immediate treatment for acute illnesses and injuries.
救急救命室に運ばれた患者はすぐに治療を受けた。
The patient who was taken to the emergency room received treatment immediately.
救急外来 is a more common term for the emergency department or outpatient emergency service, while 救急救命室 specifically refers to the emergency room itself, often used in a more clinical or institutional context.
Compound of 救急 (emergency), 救命 (life-saving), and 室 (room). The exact historical derivation is uncertain, but the term is a straightforward modern medical compound.
