Abstract
The noninvasive measurement of a patient's blood pressure is achieved automatically in high motion situations by using a dual signal channel pressure sensor in a method and system that acquires pressure waveform data while the degree of compression of an artery is being varied. Two pressure measurement channels are used, one being a main channel for monitoring pressure in the pressure transmission path, and the other being a reference channel for monitoring pressure in a wall through which a holddown force is applied. A caregiver applies the NIBP sensor to the patient. Immediately before the patient is about to engage in high motion activities or be placed in a high motion environment, the caregiver turns ON the automatic HMT function, and proceeds with his or her duties while observing the patient to ensure that the patient is quiet until the NIBP monitor acquires a certain number of waveforms without resetting. Once this has occurred, the caregiver may permit the high motion activity to begin. The automatic high motion tolerance algorithm reduces the adverse effects of high motion artifacts from the main channel using the main channel and reference channel signals.
