METHOD AND SYSTEM FOR CONTROLLING NON-INVASIVE BLOOD PRESSURE DETERMINATION BASED ON OTHER PHYSIOLOGICAL PARAMETERS
First Claim
1. A method of operating a non-invasive blood pressure (NIBP) monitor having a processing unit and a blood pressure cuff positioned on a patient to provide a cuff pressure waveform to the processing unit, the method comprising the steps of:
- determining in the processing unit whether artifacts are present in the measurement of a physiological parameter of the patient in a signal received at the processing unit from a physiological parameter monitor; and
adjusting the operation of the NIBP monitor based on the presence of artifacts in the measurement of the physiological parameter.

Abstract
A system and method for processing a cuff pressure waveform to determine the blood pressure of a patient. The processing unit of the NIBP monitoring system receives status signals from one or more physiological parameter monitors. The physiological parameter monitors each include an operating algorithm that causes the physiological parameter monitor to generate a status signal indicating whether artifacts are present that prevent the determination of the physiological parameter. When the processing unit receives the monitoring signal from the physiological parameter monitor indicating the presence of artifacts, the processing unit adjusts the operation of the NIBP monitor. The adjustment of the NIBP monitor may be to delay the beginning of the NIBP determination cycle until artifacts are no longer present from the physiological parameter monitor or to control the cuff pressure in such a manner as to keep the patient safe and comfortable until the artifacts are no longer present.

9. A method of computing a blood pressure of a patient, comprising the steps of:
-
inflating a blood pressure cuff positioned on the patient to an initial inflation pressure; deflating the blood pressure cuff in a series of pressure steps from the initial inflation pressure; determining the size of at least one oscillation amplitude in the processing unit for each pressure step; determining in the processing unit whether the amplitude determined at each pressure step is consistent with a typical blood pressure determination; determining in the processing unit whether artifacts are present in the measurement of at least one physiological parameter of the patient from at least one physiological parameter monitor when the determined oscillation amplitude is not consistent with the typical blood pressure determination; and delaying processing of blood pressure cuff waveform until artifacts are no longer present. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. A non-invasive blood pressure monitoring system, comprising:
-
a blood pressure cuff that generates a cuff pressure waveform when positioned on a patient; a processing unit coupled to the blood pressure cuff to receive the cuff pressure waveform from the blood pressure cuff and to inflate the blood pressure cuff to an initial inflation pressure and deflate the blood pressure cuff in a series of pressure steps; and at least one physiological parameter monitor in communication with the processing unit to deliver a monitoring signal to the processing unit related to a physiological parameter monitored by the physiological parameter monitor, wherein the processing unit is programmed to; determine whether artifacts are present in the measurement of the physiological parameter of the patient in the monitoring signal received at the processing unit from the physiological parameter monitor; and adjust the operation of the NIBP monitor based on the presence of artifacts in the physiological parameter. - View Dependent Claims (19, 20)
