iNIBP inflation method completes the measurement while inflating a cuff. Therefore, when 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 time of iNIBP inflation method and deflation method

323 measurement data collected in 64 cases in operating room were used to compare measurement time of iNIBP inflation method and conventional deflation method. With iNIBP technology from Nihon Kohden, the algorithm effects a slow inflation of a cuff while simultaneously detecting oscillations, then deflates the cuff as soon as 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 are 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, in comparison with the deflation method which inflates a cuff based on a pre-determined target pressure that often significantly exceeds actual SYS, leading to longer measurement times with the increased potential for patient discomfort.
