What Researchers Did
Researchers evaluated the performance of the Shangrila590 hyperbaric ventilator during volume-controlled ventilation in a multiplace hyperbaric chamber.
What They Found
Across ambient pressures from 1.0 to 2.8 atmospheres absolute and set tidal volumes from 400 to 1,000 mL, the differences between set and actual tidal and minute volumes were small and clinically insignificant. The ventilator provided stable tidal and minute volumes for set tidal volumes from 400 mL to 800 mL at all tested pressures, and for 1,000 mL at 1.0 to 2.0 atmospheres absolute.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
The study was conducted using a test lung rather than in live patients, which may not fully reflect real-world clinical conditions.
