You are using a three way stop cock and a manometer to measure cuff pressure. You added air to reach minimal occlusion volume, but you added too much. How do you remove air from the tube's cuff?

Question

Pulling back on the syringe will create negative pressure and allow air to be removed from the cuff. Squeezing the black bulb may add air instead of removing it, removing the stop cock from the pilot line may cause a sudden loss of pressure, and pressing the red button typically does not affect the cuff pressure.
