| Abstract: | Multi-place hyperbaric chambers using infusion pumps are faced with the need to change equipment due to obsolescence, or a change in devices used by the home facility. These pumps are exposed to a pressurized environment of up to 6 atm abs. Adequate pump function is essential to the safe treatment of patients, in particular those requiring vasoactive medications to support life. Six Baxter Colleague CX and one Baxter Colleague infusion pumps were tested at the standard treatment depths of 2.4 atm abs., 3 atm abs. and 6 atm abs. Prior to the testing, ventilation holes were drilled into the pressure pads on the pump face taking great care to avoid the electronic circuitry contained in the faceplate. For consistency, a single tester performed all of the testing. Using a standardized written protocol developed from the operator's manual and containing all possible functions of the device, each pump was tested three times at each standard depth. Each depth was assigned a separate pump for low volume (20cc/hour) and high volume (120cc/hr) assessment. Graduate cylinders from the hospital's Biomedical Department were used for the volume assessment to provide consistency with the facility. Volume measurements were obtained at ten minutes and twenty minutes of infusion time at 2.4 atm abs., and 3 atm abs. At 6 atm abs. a single measurement at ten minutes was done to limit exposure to the tester. All seven of the modified pumps functioned at depth. There were no alarms or malfunctions from any keystrokes. Volume error was within the limit set by the facility ( less than or = 10percent). It was noted that volume accuracy decreased when the tubing was in use for long periods of time. However, accuracy returned when the tubing was replaced. The manufacturer recommends regular tubing changes. The major issue encountered was battery life. Baxter literature does address the need to leave the units plugged in as much as possible. When the battery charge level reaches a level of 10.4 volts, the battery may be seriously compromised. After connecting the unit to 110 volts, the battery icon contained on the information screen may indicate a full charge. However, this may only be a surface charge which lasts as little as ten minutes. Baxter Colleague CX infusion pumps functioned without error at 2.4 atm abs., 3 atm abs. and 6 atm abs. Diligence is required to maintain competency of the batteries. |
