Hyperbaric decompression chamber

Warning for scuba divers in PNG

The U.S. Embassy in Port Moresby confirmed this, stating that the hyperbaric decompression chamber located in Port Moresby is currently closed and disabled, with no timeline for when it will be reactivated.

In its simplest form, the hyperbaric chamber is a cylindrical metal or acrylic tube large enough to hold one or more persons and equipped with an access hatch that retains its seal under high pressure. Air, another breathing mixture, or oxygen is pumped in by a compressor or allowed to enter from pressurised tanks.
