| Sumario: | This study examined whether the current system calibration of the pumps from a particular manufacturer, based on the input of external parameters and consequent internal readjustment by software, is suitable for the correction of infused volumes. The literature lacks studies on linear peristaltic pump infusion, especially metrological studies related to the infused volume. This deficiency relates among other factors, the high costs of infusion pumps as well as the large amount of hours required for testing. Therefore, the volumes were analyzed by infusing at minimum, intermediate and maximum rates of three linear peristaltic infusion pumps randomly taken from a hospital in the state of Paraná, which had not have maintenance in the latest 12 months and were in continuous use at the hospital. Assays were performed in flat rate of 25 ml / h in 5 different volumes over the usual range of use. Tests at a fixed volume of 10 ml varying the infusion rate at 1 ml/h, 25 ml/h and 100 ml/h were also made. For statistical analysis, an Anderson-Darling normality test was done, as most of the results did not show normal characteristics, an analysis of the confidence interval of the median for analysis of results was done. It was also necessary to do an ANOVA to check the influence of pumps and rates of infused volume, followed by a curve error analysis and a spreadsheet to calculate the measurements uncertainties. It was possible to verify that the volumes infused by the bombs from this manufacturer, at most, showed significant changes after the calibration process, decreasing variance and improving the accuracy of programmed volumes. |
