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.
Claims7
A non-transitory computer readable medium storing a plurality of programmatic instructions for processing data indicative of physiological parameters comprising:
- code for receiving respiration data generated at least in part by a bio-impedance signal source, wherein said respiration data comprises a plurality of features, wherein at least one of said features has a time of occurrence associated therewith, and wherein said respiration data is indicative of a respiration rate;
- code for receiving accelerometer data generated by an accelerometer device, wherein the accelerometer data has a time of occurrence associated therewith;
- code for correlating the time of said at least one feature of the respiration data with the accelerometer data to determine a degree of correlation;
- code for causing a low priority alarm to issue, wherein the low priority alarm is issued if said accelerometer data correlated with the respiration data is indicative of a regular respiration rate;
- and
- code for causing a high priority alarm to issue, wherein said high priority alarm is issued if said accelerometer data correlated with the respiration data is indicative of a cessation of respiratory activity.
