ObjectiveBlood pressure monitoring is an essential vital sign when caring for critically ill children. Invasive monitoring is considered the gold standard, but is not always feasible. The following study compared the CAS model 740 noninvasive blood pressure monitor with the Orion/MaxIQ NIBP module with the reference (invasive arterial measurement). We evaluated the validity of the system using the criteria provided by the Association for the Advancement of Medical Instrumentation.ResultsWe performed paired measurements of 29 critically ill neonates and children. For individual paired comparisons, the mean difference in the systolic blood pressure was 2.42 mmHg (SD ± 6.3). The mean difference in the diastolic blood pressure was -1.29 mmHg (SD ± 5.45). The percentage of readings within 5, 10, and 15 mmHg for systolic blood pressure was 65.6, 86.0, and 96.8%, respectively. The percentage of readings within 5, 10, and 15 mmHg for diastolic blood pressure was 77.7, 93, and 95.5%, respectively.ConclusionThe CAS model 740 noninvasive blood pressure monitor with the Orion/MaxIQ NIBP module fulfills the accuracy performance criteria of the Association for the Advancement of Medical Instrumentation. This model may allow for rapid and accurate noninvasive blood pressure monitoring in neonates and children.
