What Researchers Did
Researchers evaluated the flow rate of the Baxter elastomeric LV10 Infusor™ pump under normobaric and three different hyperbaric conditions.
What They Found
Initially, flow rates at 203 kPa were significantly faster than other pressures (P = 0.008), with mean rates ranging from 9.5 to 12.2 ml·h⁻¹ across conditions and time periods. However, after retesting the 203 kPa condition with a different antibiotic, there were no significant associations between flow rate and time period (P = 0.652) or pressure (P = 0.705).
What This Means for Canadian Patients
Canadian patients needing intravenous medication during hyperbaric oxygen treatment can be reassured that this pump type generally maintains consistent flow rates. This suggests the Baxter LV10 Infusor™ pump is a reliable option for medication delivery in hyperbaric environments.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A limitation was the initial use of a single antibiotic solution for all 203 kPa experiments, which required a subsequent re-evaluation.
