Diver Equipment - Submersible Decompression Chamber

It was discovered that the use of oxygen speeded up the removal of nitrogen from the diver's body. In order to safely administer oxygen a submersible decompression chamber was developed by Siebe Gorman & Co Ltd. Extensive trials at depths up to 340 feet were carried out and a safe depth of 300 feet was adopted and used until 1945.

Trimix (breathing gas) - Wikipedia

Advantages of controlling the oxygen fraction. Lowering the oxygen content increases the maximum operating depth and duration of the dive before which oxygen toxicity becomes a limiting factor. Most trimix divers limit their working oxygen partial pressure [PO 2] to 1.4 bar and may reduce the PO 2 further to 1.3 bar or 1.2 bar depending on the depth, the duration and the kind of breathing ...
