Relating to or involving lying down, reclining, or pressure from prolonged lying in one position.
From Latin decubitus (lying down) plus the adjective suffix -al. This medical term specifically describes conditions caused by or related to prolonged recumbency.
Decubital ulcers are what most people call 'bedsores'—they're injuries that develop when people lie in the same position for too long, which is why nurses constantly rotate patients.
