The duration of recompression treatment depends on the severity of symptoms, the dive history, the type of recompression therapy used and the patient's response to the treatment. One of the more frequently used [[Hyperbaric treatment schedules|treatment schedules]] is the [[Hyperbaric treatment schedules#US Navy Recompression Treatment Table 6|US Navy Table 6]], which provides hyperbaric oxygen therapy with a maximum pressure equivalent to {{convert|60|ft|m}} of seawater (2.8 bar P<sub>O<sub>2</sub></sub>) for a total time under pressure of 288 minutes, of which 240 minutes are on oxygen and the balance are air breaks to minimise the possibility of [[oxygen toxicity]].{{r|USNDM Table 6}}

A multiplace chamber is the preferred facility for treatment of decompression sickness as it allows direct physical access to the patient by medical personnel, but monoplace chambers are more widely available and should be used for treatment if a multiplace chamber is not available or transportation would cause significant delay in treatment, as the interval between onset of symptoms and recompression is important to the quality of recovery.{{r|Kindwall 1988}} It may be necessary to modify the optimum treatment schedule to allow use of a monoplace chamber, but this is usually better than delaying treatment. A US Navy treatment table 5 can be safely performed without air breaks if a built-in breathing system is not available.{{r|Kindwall 1988}} In most cases the patient can be adequately treated in a monoplace chamber at the receiving hospital.{{r|Kindwall 1988}}
