The study compares the performance of low-weight intravenous syringe infusion pumps (SIPs) to standard models in critically ill patients during helicopter transport, focusing on how altitude affects flow rates.
While standard testing showed no significant differences in flow rates at various altitudes, direct measurements revealed that low-weight SIPs often delivered inconsistent boluses rather than a steady flow, especially at 1700 m altitude.
The findings suggest that low-weight SIPs may pose risks for patients needing precise medication delivery, indicating a need to revise approval standards for these devices.
