Compressed and composed…Lt. Lyman Woollens receives instructions from Navy divers before his initial use of the Navy’s oldest certified dive chamber, affectionally known as ‘The Whale,’ for hyperbaric oxygen therapy to improve his recuperation process on Naval Undersea Warfare Center Keyport. The Navy dive team simulates setting the chamber to a depth of 45 feet of sea water pressure with the air pressure increased higher than normal to provide Woollens with 100 percent oxygen - instead of the normal 17 to 19 percent - for three 30-minute sessions. There’s a five-minute break between the sessions to prevent side effects such as oxygen toxicity, lung tissue damage and seizures. The treatment plan has him receiving 20 such treatments (Official Navy photo by Douglas H Stutz, NHB/NMRTC Bremerton public affairs officer).
