Inflight intravenous therapy: a new dimension
Aviation, Space, and Environmental Medicine
|October 1, 1975
Summary
An inflight infusion system ensures accurate intravenous fluid therapy for patients during flight. This system overcomes cabin pressure changes that disrupt conventional fluid delivery methods.
Area of Science:
- Aerospace Medicine
- Medical Devices
- Physiology
Background:
- Aircraft cabin pressure fluctuations significantly impact intravenous (I.V.) fluid flow rates.
- Ascent can cause excessive fluid discharge, while descent may lead to insufficient flow or complete cessation.
- Conventional gravity-based I.V. methods are unreliable during flight.
Purpose of the Study:
- To develop a reliable inflight infusion system for accurate I.V. fluid therapy administration to critically ill patients during aviation.
- To address the operational requirement for consistent fluid delivery despite changing atmospheric pressures.
Main Methods:
- Development of a modified precision roller pump by the USAF School of Aerospace Medicine.
- Integration of the pump into an inflight infusion system designed to counteract pressure variations.
Main Results:
- The system provides carefully controlled intravenous fluid intake throughout all phases of flight.
- It ensures consistent and accurate fluid administration, unlike conventional methods.
Conclusions:
- The developed inflight infusion system successfully overcomes the challenges posed by aircraft cabin pressure changes.
- This innovation allows for reliable and precise I.V. fluid therapy in the aviation environment.
