What Researchers Did
Researchers surveyed 98 hyperbaric oxygen treatment (HBOT) centers via questionnaire to determine their evaluation practices for pulmonary blebs or bullae and the prevalence of pulmonary barotrauma (PBT).
What They Found
Out of 98 responding centers, 65 (66.3%) reported treating patients with lung air cysts, primarily using X-rays for screening in those with a history of lung disease. The prevalence of pulmonary barotrauma in these centers was found to be extremely low, calculated at 0.00045%.
What This Means for Canadian Patients
Canadian patients with pulmonary blebs or bullae may find that hyperbaric oxygen treatment is still an option, given the very low reported risk of pulmonary barotrauma. Patients should discuss appropriate screening methods, such as X-rays, with their healthcare provider before undergoing HBOT.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
Limitations include the survey-based methodology, which relies on self-reported data, and the acknowledged insufficiency of X-ray as a screening tool.
