Comparative StudyComparison of three intravenous infusion pumps for monoplace hyperbaric chambers.
We compared the infusion accuracy of the Baxter Flo-Gard 6201, IVAC 530 and Abbott Lifecare 3HB pumps with saline and enteral formula at chamber pressures from 86.1 kPa (0.85 atm abs) to 304 kPa (3.0 atm abs). The Baxter pump infused +/- 10% saline at all tested pressures and rates (1-1,999 ml/hr). At 1 ml/hour, the IVAC infused 18% more saline than expected (86.1 kPa). ⋯ Enteral infusions (100 ml/hour) resulted in -20% to +12% fluid volume discrepancies. In conclusion, the Baxter pump had the best overall performance. Changes observed during compression and decompression may be clinically important.
