What Researchers Did
Researchers studied specific blood markers in 31 patients with immersion pulmonary edema (IPE) or decompression sickness (DCS) and 10 healthy divers to help tell these two diving-related conditions apart.
What They Found
They found that copeptin, a stress marker, was high in 68% of IPE patients compared to 25% of DCS patients. Ischemia-modified albumin, an ischemia marker, was elevated in 68% of IPE patients versus 16% of DCS patients. Additionally, brain-natriuretic peptide (BNP), a heart failure marker, was high in 53% of IPE patients, while DCS patients had normal levels.
What This Means for Canadian Patients
For Canadian divers, these findings suggest that specific blood tests could help doctors quickly and accurately distinguish between immersion pulmonary edema (IPE) and decompression sickness (DCS). This improved diagnosis is important because DCS is a Health Canada-recognized indication for hyperbaric oxygen therapy (HBOT), ensuring patients receive appropriate and timely care.
Canadian Relevance
This study, conducted by non-Canadian authors, covers decompression sickness (DCS), which is a Health Canada-recognized indication for hyperbaric oxygen therapy.
Study Limitations
The study's main limitation is its relatively small number of participants, which may affect the generalizability of the findings.
