What Researchers Did
Researchers evaluated how accurately a specific infusion pump delivered fluids at different rates under normal pressure (1 ATA) and hyperbaric pressure (2 ATA).
What They Found
They observed significant differences in pump delivery between 1 ATA and 2 ATA. During hyperbaric oxygenation, delivery rates changed by approximately -4% to +2%. Although statistically significant, the effect of 2 ATA pressure was small and likely not important for practical hyperbaric oxygen therapy.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study only evaluated one specific model of infusion pump, and the findings may not apply to other pump types or different hyperbaric pressures.
