Methods and systems to determine multi-parameter managed alarm hierarchy during patient monitoring

摘要

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.

主权项

1. A non-transitory computer readable medium storing a plurality of programmatic instructions for processing data indicative of physiological parameters comprising:
code for receiving ECG data generated at least in part by an ECG device, wherein said ECG data comprises a plurality of features, wherein at least one of said features has a designation associated therewith and a time of occurrence associated therewith, and wherein said ECG data is indicative of a ventricular tachycardia condition; code for receiving blood pressure and pulse data indicative of a patient's pulse response, wherein said blood pressure and pulse data are obtained from an invasive blood pressure monitoring device separate from said ECG device and wherein said pulse data has a designation associated therewith and a time of occurrence associated therewith; code for correlating the designation and time of said at least one feature of the ECG data with the designation and time of the pulse data to determine a degree of correlation; code for causing a low priority alarm, indicative of a noisy ECG, to issue, wherein the low priority alarm is issued if said pulse data correlated with the ECG data is indicative of a regular rhythm and amplitude; and code for causing a high priority alarm to issue, wherein said high priority alarm is issued if said pulse data correlated with the ECG data is indicative of a cessation of pulsatile activity.
