A sleep study usually involves getting monitored overnight with a polysomnogram.

睡眠研究通常包括在夜间进行多导睡眠监测。

A polysomnogram tracks things like brain movement, oxygen and carbon dioxide blood levels, vital signs, and outward symptoms like snoring and movement.

多导睡眠监测可以追踪大脑活动、血液中氧气和二氧化碳浓度、生命体征，以及外在体征如打鼾和活动等。
