Abstract:
1. A method of monitoring blood pressure in a patient, the method comprising the steps of: positioning a blood pressure cuff of a non-invasive blood pressure (NIBP) monitor on the patient; providing a continuous, non-invasive blood pressure (CNIBP) monitor operable to continuously estimate the blood pressure of the patient and generate a continuous blood pressure estimate that includes at least an estimated systolic blood pressure; calculating a target inflation pressure for the NIBP monitor based upon the continuous blood pressure estimate determined by the CNIBP monitor before inflation of the blood pressure cuff, wherein the target inflation pressure is the estimated systolic blood pressure plus an offset value, wherein the offset value is determined as a statistical function of the estimated systolic pressure over a pre-determined number of the previous beats; inflating the blood pressure cuff to the target inflation pressure; continuously decreasing the pressure in the blood pressure cuff while monitoring for oscillometric pulses in the blood pressure cuff in the NIBP monitor; and calculating the systolic pressure, mean arterial pressure and diastolic pressure based upon the oscillometric pulses detected during deflation of the blood pressure cuff.
