摘要： A method and system for operating a non-invasive blood pressure monitor that utilizes an SpO2 plethysmograph waveform to determine the initial inflation pressure for the NIBP monitor. A pulse sensor is placed on the patient's limb distal to the blood pressure cuff and provides a pulse waveform to the NIBP monitor. The NIBP monitor calculates a second derivative of the pulse waveform, which includes a series of acceleration peaks corresponding to pulse signals within the pulse waveform. When the blood pressure cuff reaches systolic pressure, the acceleration peaks contained within the acceleration waveform are eliminated, thus providing an indication that the cuff pressure has reached systolic pressure for the patient. Use of the SPO2 plethysmograph signal to determine the initial inflation pressure reduces both the over-inflation of the blood pressure cuff and the under-inflation of the blood pressure cuff, which increases the rate at which the blood pressure measurement can be made while increasing patient comfort.

摘要： A blood pressure measurement system that utilizes a non-invasive blood pressure (NIBP) monitor having a blood pressure cuff and pressure transducer. The measurement system provides a plurality of separate processing techniques that each receive a plurality of oscillometric waveform sample values generated using the pressure transducer. Each of the processing techniques separately generates a set of envelope points based upon the oscillometric data values. The sets of envelope points are appropriately scaled such that the sets of scaled envelope points are combined with each other to create a set of combined, scaled envelope points. Various different methods can be used to scale the sets of envelope points prior to the combination of the scaled envelope points. Based upon the combination of scaled envelope points, the blood pressure is calculated and displayed by the NIBP monitor.

摘要： Blood pressure is measured using the pulse transit time required for the blood volume pulse to propagate between two locations in an animal. Impedance plethysmography is employed to detect when the blood volume pulse occurs at one location. The plethysmograph may detect thoracic impedance to determine when the aortic heart valve opens or it may detect impedance at one location on a limb of the animal. Occurrence of the blood volume pulse at another location can be determined by impedance plethysmography or another technique, such as pulse oximetry. The calculation of cardiac stroke volume can be employed to compensate the derivation of the blood pressure for effects due to blood vessel compliance. A nonblood pressure monitor may periodically provide a reference blood pressure measurement that is used calibrate derivation of the blood pressure based on the pulse transit time.

摘要： 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.

摘要： A system and method for processing oscillometric data from a plurality of pressure steps to determine the blood pressure of a patient. A heart rate monitor connected to the patient acquires the patient's heart rate. A time-to-frequency domain converter receives oscillometric data and converts the oscillometric data into the frequency domain. Based upon the calculated heart rate, the system and method filters the frequency domain oscillometric signal with pass bands centered at the fundamental frequency and at least one fundamental frequency. The energy of the frequency domain signal within the pass bands is compared to at least a portion of the energy of the frequency domain oscillometric signal outside of the pass bands. Based upon the comparison, the signal determines whether the signal at the current pressure step should be utilized in calculating the blood pressure of the patient.
