Here’s what trips people up: the wall suction doesn’t control how much suction your patient gets. The dial on the chest tube does. The wall suction is just the power source. It has to be high enough to open the indicator. The dial sets the amount.
Quick check every time you walk in the room:
✔️ Is the orange indicator open?
✔️ Does the dial match the order?
Save this for your next shift with a chest tube, and send it to a nurse who’s still getting comfortable with them.
