Yes, Pacific Grove has the only hyperbaric chamber in the area.
As a footnote, IF you (or anyone else, for that matter) are showing signs of de-compression sickness, DO NOT go directly to the chamber. Treatment in PG's hyperbaric chamber comes after a physician has diagnosed the DCS. The chamber is not staffed with the necessary medical personnel. The closest 24-hour medical treatment facility is Community Hospital of the Monterey Peninsula (CHOMP).
Its more information than what you asked for; however, I felt this was important stuff to add.
