iNIBP

The advantages of iNIBP are best demonstrated when patient's blood pressure is varying, for example during surgery. As iNIBP inflates while sensing blood pressure variation, it can complete the measurement in a shorter amount of time without applying excessive and unnecessary pressure to the patient.

323 measurement data collected in 64 cases in the operating room were used to compare measurement time of iNIBP inflation method and conventional deflation method. With the iNIBP technology from Nihon Kohden, the algorithm affects a slow inflation of a cuff while simultaneously detecting oscillations, then deflates the cuff as soon as systolic blood pressure (SYS) is determined.

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.

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.
