• Treatment table 61 (US Navy Table 5) may be used for the following conditions:
• Divers with Decompression Sickness (DCS) presenting with limb pain, cutaneous or lymphatic manifestations only (see Note 1)
• Asymptomatic omitted decompression (missed stops from a decompression dive but with no symptoms)
• Follow up re-treatments of Decompression Illness (DCI)
• Carbon monoxide poisoning
• Gas gangrene


• Note 1: If the stricken diver does not have complete relief from symptoms after 10 minutes at 18m the treatment must be changed to the Royal Navy Table 62.

• Procedure:
1. Descend to 18msw over 2-5 minutes, stopping only if the diver or tender has difficulty clearing ears
2. Treatment time starts once 18m depth is reached
3. Once at depth, the diver should be re-assessed for any neurological symptoms, if any are present, the treatment should be switched to Table 62
4. If the divers symptoms completely resolve within 10 minutes of breathing Oxygen at 18 msw, table 61 may be completed as prescribed. (see Note 2)
5. The tender should breathe Oxygen during both ascents, from 18 to 9 msw and from 9 msw to the surface


• Note 2: In practical terms, a stricken diver is unlikely to recover completely within 10 minutes unless the diver has been recompressed very quickly after the offending dive (as may be the case if a hyperbaric chamber is on board or very close). This means that the vast majority of divers with symptoms of decompression sickness (DCS) will either be switched to or will have been prescribed the Royal Navy Table 62.
