What Researchers Did
Researchers investigated how changes in atmospheric pressure, specifically hyperbaric conditions, affected the insulin delivery of three modern insulin pump models.
What They Found
The study found that increasing atmospheric pressure from 1 to 1.3 ATA decreased insulin release by about 0.2 units every 10 minutes. Conversely, returning pressure from 1.3 to 1 ATA led to an unintended insulin delivery of approximately 0.3 units every 10 minutes. This effect was linked to air bubbles in the pump system, not the set insulin rate.
Canadian Relevance
No direct Canadian connection identified.
Study Limitations
This study was conducted in a laboratory setting using only three specific insulin pump models, rather than involving actual patients.
