Which of the following is a sign of facemask squeeze?

• A. Pain and suction in the face
• B. Nausea
• C. Bruising on legs
• D. Shortness of breath only

Answer: (A)

Facemask squeeze happens when the air space between the face and the mask can’t equalize as ambient pressure increases underwater. The mask is pressed inward against the face, creating a suction effect on the skin and soft tissues around the mask seal. That suction together with facial pain is the telltale sign.

Nausea, bruising on the legs, or shortness of breath alone point to other issues (like decompression problems or broader bodily symptoms) and don’t specifically indicate a mask seal squeeze.
