Advantages of iNIBP
The iNIBP inflation method completes the measurement while inflating the cuff. Therefore, compared to the conventional method, the iNIBP measurement time is shorter and target inflation pressure is lower, maximizing patient comfort while preserving the accuracy of this important parameter.
Histogram of measurement times of iNIBP inflation method and deflation method
323 measurement data collected from 64 cases in the operating room were used to compare the measurement time of the iNIBP inflation method and the conventional deflation method. With iNIBP technology from Nihon Kohden, the algorithm effects the slow inflation of a cuff while simultaneously detecting oscillations, then deflates the cuff as soon as the systolic blood pressure (SYS) is determined.
Measurement simulation：SYS elevated to 200mmHg
iNIBP can complete the measurement in a shorter amount of time as it inflates the cuff while sensing blood pressure variation and detecting oscillations, whereas the deflation method needs to repeat the inflation-deflation cycle when the target inflation pressure based on previous systolic pressure measurements is comparatively low.
Measurement simulation: SYS dropped to 100mmHg from 200mmHg
iNIBP inflates the cuff to only slightly above the SYS while detecting oscillations and completes the measurement in a shorter amount of time than the deflation method, which inflates the cuff based on a pre-determined target pressure that often significantly exceeds the actual SYS, leading to longer measurement times with the increased potential for patient discomfort.
