The water column in the suction control determines what aspect of suction?

Explanation:
Regulating the negative pressure delivered to the chest is achieved by the water column in the suction control. The height of that water column sets the suction level: a taller column produces stronger negative pressure, while a shorter column reduces it. This keeps suction within a safe, controlled range and adapts to the clinical needs. The water column does not store drainage fluid (that’s the collection chamber), it does not monitor patient hydration, and it does not power a pump.
