|November 1, 1983
Summary
This study found that six infusion pumps in Canada accurately delivered medication volumes within 5% of the set rate. Pump performance was consistent, regardless of infusion bag height or cannula size, ensuring reliable clinical accuracy.
Area of Science:
- Medical Devices
- Pharmacology
- Clinical Engineering
Background:
- Accurate medication delivery is crucial for patient safety.
- Infusion pumps are widely used in clinical settings.
- Understanding volumetric accuracy is essential for reliable drug administration.
Purpose of the Study:
- To evaluate the volumetric accuracy of six commonly used infusion pumps in Canada.
- To determine the consistency of infusion pump performance under various conditions.
Main Methods:
- Tested six different infusion pump models available in Canada.
- Measured delivered volumes at hourly rates ranging from 20-200 ml.
- Assessed pump performance with varying infusion bag heights and cannula sizes.
Main Results:
- All tested infusion pumps delivered volumes within ±5% of the indicated value.
- Pump accuracy remained consistent across the tested flow rates.
- Performance was not significantly affected by changes in infusion bag height or cannula size.
Conclusions:
- The examined infusion pumps demonstrate reliable volumetric accuracy for clinical use.
- Consistent performance suggests these devices are dependable for medication administration.
- The findings support the use of these infusion pumps for achieving clinical accuracy.
