What Researchers Did
Clinicians reported a case of acute noncardiogenic pulmonary oedema occurring during HBOT decompression in a 35-year-old male being treated for carbon monoxide poisoning, describing the presentation, management, and proposed mechanism.
What They Found
The patient developed dyspnea and severe coughing during decompression, with CT imaging confirming acute pulmonary oedema. He was intubated and treated with diuretics, steroids, and bronchodilators, achieving complete resolution by 3-month follow-up.
Canadian Relevance
Carbon monoxide poisoning is an OHIP-covered indication for HBOT in Ontario. The complication described is relevant to patient safety protocols at Canadian hyperbaric facilities.
Study Limitations
Single case report; the proposed hemodynamic mechanism during decompression is speculative and requires further investigation to confirm.
