MARITIME – DIVE & UNDERWATER OPERATION CALCULATOR
Hyperbaric Recompression
A precise tool.
What is the Hyperbaric Recompression & How does it work?
Hyperbaric recompression therapy uses increased ambient pressure to accelerate the elimination of inert gases dissolved in a diver’s tissues, thereby reducing the risk of decompression sickness. By raising the surrounding pressure, the nitrogen bubbles that may have formed during ascent are forced to shrink and dissolve back into the bloodstream, where they can be safely expelled through respiration.The treatment schedule is carefully calculated based on the dive profile, including maximum depth, bottom time, and surface interval. These parameters determine the required pressure level and exposure time to achieve sufficient nitrogen wash‑out while avoiding oxygen toxicity, which becomes a concern as the partial pressure of oxygen (P_O2) rises with depth.Modern recompression chambers allow precise control of both pressure and the oxygen fraction of the breathing gas. By adjusting the oxygen percentage, clinicians can deliver a therapeutic dose that promotes tissue oxygenation without exceeding safe P_O2 limits. The schedule is therefore a balance between pressure, oxygen concentration, and exposure duration.
P = P_{surface} + frac{depth}{10}

Frequently Asked Questions
What is hyperbaric recompression therapy?
It’s a medical treatment that uses increased pressure to help eliminate inert gases from a diver’s body, reducing the risk of decompression sickness.
How does hyperbaric recompression work?
By raising the surrounding pressure, nitrogen bubbles in a diver’s tissues shrink and dissolve back into the bloodstream, where they can be expelled through respiration.
Why is the treatment schedule important?
The schedule is carefully calculated based on the dive profile to ensure effective elimination of inert gases and prevent decompression sickness.
What factors are considered in the dive profile?
Factors include maximum depth, duration of dives, and ascent rates to determine the appropriate treatment schedule.
Can this calculator be used for any type of diving?
Yes, it can be used for various types of diving, including recreational, technical, and commercial diving.
Are there any risks associated with hyperbaric recompression therapy?
While generally safe, potential risks include barotrauma, oxygen toxicity, and minor side effects like ear pain or dizziness.
How long does a typical hyperbaric recompression treatment last?
The duration varies based on the dive profile and individual needs, but treatments can range from several hours to multiple days.
