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 and system for operating a non-invasive blood pressure monitor that utilizes an SpO2 plethysmograph signal to determine the initial inflation pressure for the blood pressure cuff of the NIBP monitor. A pulse sensor is placed on the patient's limb distal to the blood pressure cuff such that as the blood pressure cuff is inflated, the pulse signals from the pulse sensor will be reduced. When the blood pressure cuff reaches systolic pressure, the pulse signals from the pulse sensor will be initially attenuated and eventually eliminated, thus providing an indication that the cuff pressure has reached systolic pressure for the patient. The central processor of the NIBP monitor compares the pulse signals during cuff inflation to an average pulse signal and terminates the inflation of the blood pressure cuff upon sufficient attenuation. The 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 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 method and technique for the continuous, non-invasive measurement of blood pressure. The blood pressure measurement technique of the present invention utilizes ultrasound measurements to determine the diameter of the blood vessel in which the blood pressure is being measured as well as the flow rate of blood at both an input point and an output point along the blood vessel. The system utilizes a transmission line model to relate various blood vessel measurements with electrical components. The transmission line model, in combination with data management techniques including state variable representations and Kalman filtering, is used to develop a blood pressure measurement in real time.

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.
