Mask Squeeze Definition and Overview

Mask squeeze, also known as face squeeze is a feeling that occurs when scuba diving as a result of failing to equalize the pressure inside the diving mask. As a diver descends under the surface of the water, the pressure increases, which exerts pressure on the body. The air in the mask has more pressure put on it, and therefore becomes painful against the face unless the pressure is allowed to equalize. The way to keep pressure equalized in the mask is to exhale through the nose.

Mask Squeeze Symptoms

Facial bruising and redness
Facial pressure
Nosebleed
Red eyes or face
Changes in vision (rare)

Mask Squeeze Treatment

If a person experiences a mask squeeze, that person should discontinue diving until healed. Mask squeeze can be prevented by equalizing the pressure in the mask as the diver descends on their dive.

When to Seek Medical Care for Mask Squeeze

If changes in vision occur, see a doctor or eye specialist as soon as possible.
