Table 8. Comex accelerated saturation decompression procedures; FO₂ – inspired fraction of oxygen; msw – metres of seawater; PO₂ – inspired pressure of oxygen .

Depth (msw)	Chamber gas	Ascent rate (msw·h-1)
Decompression from from not deeper than 130 msw
130–16	PO2 = 60 kPa	1.4
16–0	FO2 = 23%	0.6
Decompression from from not deeper than 90 msw
90–20	PO2 = 70 kPa	1.6
20–15	FO2 = 23%	1.2
15–0	FO2 = 23%	0.6
Decompression from from not deeper than 70 msw
70–25	PO2 = 80 kPa	1.7
25–15	FO2 = 23%	1.2
