What Researchers Did
Researchers used a mathematical model to predict the absorption time of cerebral artery air emboli (CAAE) of varying volumes.
What They Found
The model predicted that cerebral artery air emboli (CAAE) would take at least 40 hours to absorb with 40% inspired oxygen. For CAAE large enough to be detected by CT, absorption times were calculated to be at least 15 hours. The study suggests considering hyperbaric oxygen therapy if large CAAE are visualized on CT, even with transfer delays.
What This Means for Canadian Patients
If a Canadian patient is suspected of having a massive cerebral air embolism, a CT scan should be performed to visualize the emboli. If large emboli are present, hyperbaric oxygen therapy should be considered, even if patient transfer to a specialized facility is required.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The findings are based on a mathematical model rather than direct clinical observation or patient data.
