DANのガイドラインに出てくる、米国海軍の「Return to Diving」ポリシーの「Table」って意味がわからなかったので調べてみた。
おお、USはなんて進んでいるのだろう。US NAVY DIVING MANUAL Rev.4が公開されていた。すごい。某自衛隊ってこんな資料公開しているのかな?調べてみたけどないんよ、これが（やっぱり）。
US NAVY DIVING MANUALを見ると私が受けている治療はTable 5とTable 6のようだ。（カルテにもそう書いてあった）でも加圧は3分じゃなくもうちょっと時間をかけるよ。
Table 4やTable 7じゃなくてよかった。だって「giving up diving altogether may be appropriate」だもん。
Treatment Table 5
- Descent rate – 20 ft/min.
- Ascent rate – Not to exceed 1 ft/min. Do not compensate for slower ascent rates. Compensate for faster rates by halting the ascent.
- Time on oxygen begins on arrival at 60 feet.
- If oxygen breathing must be interrupted because of CNS Oxygen Toxicity, allow 15 minutes after the reaction has entirely subsided and resume schedule at point of interruption (see paragraph 21-5.5.6.1.1)
- Treatment Table may be extended two oxygen-breathing periods at the 30-foot stop. No air break required between oxygen-breathing periods or prior to ascent.
- Tender breathes 100 percent O2 during ascent from the 30-foot stop to the surface. If the tender had a previous hyperbaric exposure in the previous 12 hours, an additional 20 minutes of oxygen breathing is required prior to ascent.
Treatment Table 6
- Descent rate – 20 ft/min.
- Ascent rate – Not to exceed 1 ft/min. Do not compensate for slower ascent rates. Compensate for faster rates by halting the ascent.
- Time on oxygen begins on arrival at 60 feet.
- If oxygen breathing must be interrupted because of CNS Oxygen Toxicity, allow 15 minutes after the reaction has entirely subsided and resume schedule at point of interruption (see paragraph 21-5.5.6.1.1).
- Table 6 can be lengthened up to 2 additional 25-minute periods at 60 feet (20 minutes on oxygen and 5 minutes on air), or up to 2 additional 75-minute periods at 30 feet (15 minutes on air and 60 minutes on oxygen), or both.
- Tender breathes 100 percent O2 during the last 30 min. at 30 fsw and during ascent to the surface for an unmodified table or where there has been only a single extension at 30 or 60 feet. If there has been more than one extension, the O2 breathing at 30 feet is increased to 60 minutes. If the tender had a hyperbaric exposure within the past 12 hours an additional 60-minute O2 period is taken at 30 feet.
