Decompression Sickness: Current Recommendations.

Area of Science:

• Physiology
• Aerospace Medicine
• Diving Medicine

Background:

• Decompression sickness (DCS), or "bends," results from inert gas supersaturation and bubble formation during pressure reductions.
• It affects individuals in compressed air environments (diving, caisson work) and during rapid altitude changes (aviation, spaceflight).
• Mild pressure reductions, like commercial flights post-scuba, can also trigger DCS.

Purpose of the Study:

• To outline the pathophysiology, clinical manifestations, and management of decompression sickness.
• To emphasize the importance of immediate evaluation and treatment protocols for DCS.

Main Methods:

• Clinical evaluation including patient history (diving/altitude exposure, symptom onset) and neurological examination.
• Immediate management involving oxygen administration and fluid resuscitation (oral/intravenous).
• Definitive treatment utilizing hyperbaric oxygen therapy.

Main Results:

• DCS presents with a wide spectrum of symptoms, from pain and rash to severe neurological deficits and cardiorespiratory collapse.
• Initial oxygen and fluid resuscitation are critical supportive measures.
• Hyperbaric oxygen therapy is the definitive treatment for DCS.

Conclusions:

• Prompt recognition and management, including oxygen and hyperbaric therapy, are key to successful DCS treatment.
• While severe cases may have residual effects, appropriate treatment generally leads to favorable patient outcomes.
• Understanding DCS triggers and manifestations is vital for at-risk populations.
