What Researchers Did
Researchers tested how two Dräger Oxylog 1000 ventilators performed when used with a mechanical test lung system under increasing pressure, up to 18 meters' sea water (284 kPa), in a hyperbaric chamber.
What They Found
They found that as pressure increased to 284 kPa, the Dräger Oxylog 1000 ventilator delivered a decreased tidal volume and airway pressure, and an increased respiratory rate. The two ventilators tested showed different absolute changes in these measurements at various depths.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study tested only two ventilators using a mechanical test lung system, which may not fully reflect performance in actual patients or across a wider range of devices.
