Under the watchful eye of Navy Diver 2nd Class Joseph Ziemba, inside tender responsible for safety, retired Senior Chief Hospital Corpsman Robert Johnson receives hyperbaric oxygen therapy to help prevent complications from radiation treatment in the Navy's oldest certified dive chamber. The air pressure in the dive (recompression) chamber is increased higher than normal, thus simulating being under water, with Johnson's lungs - entire body actually - receiving 100 percent oxygen through the mask instead of the normal approximately 21 percent oxygen range at sea level (Official Navy photos by


Under the watchful eye of Navy Diver 2nd Class Joseph Ziemba, inside tender responsible for safety, retired Senior Chief Hospital Corpsman Robert Johnson receives hyperbaric oxygen therapy to help prevent complications from radiation treatment in the Navy's oldest certified dive chamber. The air pressure in the dive (recompression) chamber is increased higher than normal, thus simulating being under water, with Johnson's lungs - entire body actually - receiving 100 percent oxygen through the mask instead of the normal approximately 21 percent oxygen range at sea level (Official Navy photos by Douglas H Stutz, NHB Public Affairs).
