Iron Lung
Definition
A historical medical device, a type of negative-pressure mechanical ventilator that encases the body (excluding the head) to facilitate breathing for patients with severe respiratory failure, famously used during mid-20th-century polio outbreaks.
A 2022 indie horror video game by David Szymanski, where players pilot a cramped submarine through a lightless ocean of blood on a rogue planet, blending cosmic dread with claustrophobia.
A 2026 sci-fi horror film adaptation of the game, directed by and starring YouTuber Markiplier (Mark Fischbach) alongside Troy Baker, premiering amid viral YouTube hype.
