Embodiment Construction

[0024] In one embodiment, the present specification discloses systems and methods for centrally analyzing multiple physiological parameters and using the results to escalate, downgrade or suppress alert notifications. The present specification provides the benefits of generating more specific patient alarms and reducing the occurrence of false alarms so that monitoring personnel can perform more efficiently.

[0025] In one embodiment, ECG parameters are considered together with one or a combination of the following sensor measurements: invasive blood pressure (IBP); non-invasive blood pressure (NIBP); and blood oxygen levels such as via pulse oximetry (SpO 2 ). For each parameter there is a corresponding waveform signal generated by measuring and sampling the signal leaving the transducer.

[0026] For ECG, the waveform is derived from the electrical signal detected by subcutaneously placed electrodes in response to the propagation of the electrical signal in the heart muscl...

Abstract

The present specification discloses systems and methods of patient monitoring in which multiple sensors are used to detect physiological parameters and the data from those sensors are correlated to determine if an alarm should, or should not, be issued, thereby resulting in more precise alarms and fewer false alarms. Electrocardiogram readings can be combined with invasive blood pressure, non-invasive blood pressure, and / or pulse oximetry measurements to provide a more accurate picture of pulse activity and patient respiration. In addition, the monitoring system can also use an accelerometer or heart valve auscultation to further improve accuracy.

Description

technical field [0001] The present specification invention relates to patient monitoring systems. In particular, the present specification discloses systems and methods for analyzing multiple physiological parameters to escalate, downgrade or suppress alarm conditions. Background technique [0002] Most patient monitoring is usually accomplished by measuring and observing multiple physiological parameters such as: ECG (electrocardiogram), pulse oximetry (which involves measuring blood oxygen levels or SpO 2 ), respiration (derived from the ECG signal or from other parameters), invasive blood pressure (or IBP involving direct measurement of blood pressure from an indwelling catheter), and noninvasive blood pressure (or NIBP involving the use of automated oscillometric methods). [0003] Typically, these physiological parameters have a set of vital signs and derived measurements that can be configured to alert caregivers if the measurements move outside configured ranges. Ea...
