the chokes

Also found in: Dictionary, Thesaurus, Encyclopedia.


A clinical complex caused by rapid whole-body decompression, with acute intravascular “boiling” of nitrogen and resultant morbidity (and mortality) in scuba divers and high-altitude pilots or workers in high-pressure environments (e.g., caissons) in chronic decompression sickness.

Clinical findings
Headache, nausea, vomiting, vertigo, tinnitus, dyspnoea, tachypnoea, joint and abdominal pain; nitrogen gas in the brain causes air bubbles in meningeal vessels separating the blood “column”, convulsions, shock and possibly death.
