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 method and system for determining when to make a reversion to smaller cuff pressure steps during an oscillometric blood pressure measurement is disclosed. The method and system comprise comparing conformance of oscillometric envelope blood pressure data with previous blood pressure data, including measuring a shift between the oscillometric envelope blood pressure data and an oscillometric envelope derived from the previous blood pressure data. In addition, the method and system include making a reversion decision based on whether the shift exceeds an allowable threshold. Once a reversion decision is made a subsequent decision may be made as to the need for increasing the cuff pressure level.

摘要： A vital sign monitoring system that can be used with multiple patients and utilizes historic patient data information for the patient to optimize the process of obtaining current vital sign measurements. Each patient is identified with a unique patient identification device that is automatically detected by the vital sign monitor. The vital sign monitor communicates with a medical records database and obtains historic patient data information and previously diagnosed characteristics for the patient identified by the patient identification device. The historic patient data information and previously diagnosed characteristics of the patient can be utilized by the vital sign monitor to set alarm limits for the vital sign measurements and automatically adjust the blood pressure estimation algorithm of the NIBP monitor.

摘要： A method of operating a non-invasive blood pressure (NIBP) monitor that includes a blood pressure cuff and a pressure transducer. The method initially inflates the blood pressure cuff to a level above systolic pressure and begins to deflate the pressure cuff using a continuous or linear deflation technique. During the linear deflation of the pressure cuff, the oscillation pulses from the pressure transducer are obtained and compared to predicted pulse estimates. If the obtained oscillation pulses vary from the predicted pulse estimates, the linear deflation technique is interrupted and the pressure cuff is then deflated in a sequence of distinct pressure steps. During each pressure step, the oscillation pulses are obtained and the pressure cuff is not deflated to the next pressure step until the oscillation pulses correspond to each other.

摘要： A method of utilizing a maternal-fetal monitoring system to monitor the physiological properties of both a maternal patient and a fetus. A series of ECG electrodes are placed across the maternal patient's abdomen and receives ECG input waveforms across sixteen separate channels. The sixteen channels of information are processed using an ICA algorithm to generate a series of ICA output waveforms and a transfer matrix. Following the current epoch, the transfer matrix is applied to the input waveforms on a continuous basis. The conditioned input waveforms are displayed immediately following the first epoch and prior to the expiration of a subsequent epoch. The transfer matrix for the second epoch is combined with the transfer matrix for the first epoch to generate an updated transfer matrix. Various filtering operations on the transfer matrix coefficients may be used to find the updated transfer matrix before the end of the current epoch.

摘要： A method of utilizing maternal-fetal monitoring system to monitor the physiological properties of both a maternal patient and a fetus. The method places a series of ECG electrodes across the maternal patient's abdomen and receives ECG input waveforms across a plurality of separate channels. The method processes the channels using an ICA algorithm to generate a series of ICA output waveforms. The ICA output waveforms are analyzed for each individual epoch to determine which of the channels include a maternal signal or a fetal signal source. Based upon the determination of which channel includes the fetal and maternal signals, further processing is carried out on the ICA output waveform on the identified channel to obtain physiological properties for the patient and the fetus. During the next epoch, the same signal processing occurs, such that the system can identify the fetal and maternal signals even as the fetal and maternal jump channels from one epoch to another.
