20100022903 | SYSTEM AND METHOD FOR SIGNAL QUALITY INDICATION AND FALSE ALARM REDUCTION IN ECG MONITORING SYSTEMS - An electrocardiogram (ECG) monitoring system configured to determine an index that comprises a set of indicators, where each indicator is indicative of a level of signal quality in an ECG lead. Further, the ECG monitoring system assigns a first indicator from the set of indicators to a first ECG lead signal and communicates the first indicator to a user. | 01-28-2010 |

20080269626 | FALSE POSITIVE REDUCTION IN SPO2 ATRIAL FIBRILLATION DETECTION USING AVERAGE HEART RATE AND NIBP - The method and system includes detecting atrial fibrillation in a patient by monitoring the blood oxygen saturation level over a period of time. The method and system produces a plethysmographic waveform from the monitored blood oxygen saturation level and analyzes the plethysmographic waveform and detected intervals and determines whether the patient is in atrial fibrillation. The method and system is preferably implemented in a software application and may be configured to report to the user on the current state of atrial fibrillation (AFIB) and a current trend. | 10-30-2008 |
20090275807 | METHOD FOR MANAGING ALARMS IN A PHYSIOLOGICAL MONITORING SYSTEM - A method for managing alarm events in a physiological monitoring system is described. The method includes validating the accuracy of alarm events by checking if the alarm events are noise events. The method further includes identifying a pattern in alarm sequence or an alarm rate of at least one alarm type associated with the alarm events. The alarm rate is the frequency of the occurrence of alarm events for the particular alarm type. Based on the identified pattern in the alarm sequence and the alarm rate and patient data, an alarm level associated with the alarm type is adjusted. The hospital staff is notified depending on the criticality of the adjusted alarm level. Further, the alarm signals are suppressed when either a patient intervention or a pause signal is detected by the physiological monitoring system. | 11-05-2009 |
20090299150 | PATIENT MONITORING SYSTEM WITH HEALTH STATUS INDICATOR - A patient monitoring system is disclosed herein. The patient monitoring system includes a computer adapted to assess the health of a patient, and to generate a health status indicator for the patient. The health status indicator comprising a visual gradient adapted to visually convey the assessed health of the patient. The system also includes a display operatively connected to the computer. The display is configured to display the health status indicator comprising the visual gradient. | 12-03-2009 |

20150238151 | SYSTEM AND METHOD FOR PERFUSION-BASED ARRHYTHMIA ALARM EVALUATION - A method of prioritizing arrhythmia alarms based on one patient's perfusion level includes receiving arterial blood pressure, electrocardiogram heart rate, and arterial pulse rate values of the one patient during a same time window. Analysing the set of blood pressure values to determine if an arrhythmia event is indicated, where if an arrhythmia event is indicated, the method includes calculating a systolic blood pressure (SBP) ratio, comparing the SBP ratio to a first predetermined threshold, and if the SBP ratio is less than or equal to the first predetermined threshold, then activating a non-perfusion alarm. If the SBP ratio is greater than the first predetermined threshold, then calculating a standard deviation of a rate differential between the heart rate and the pulse rate values, and if the standard deviation is greater than a second predetermined threshold, then activating the non-perfusion alarm. A system and non-transitory computer media is also presented. | 08-27-2015 |

20100278738 | METHOD TO DETECT AND MONITOR ISCHEMIA IN TRANSPLANTED ORGANS AND TISSUES - Disclosed is a method of detecting and/or monitoring ischemia in a tissue or organ, such as a free flap transfer. The method includes the steps of measuring in real time or near-real time interstitial glucose concentration, or rate of change of interstitial glucose concentration over time, or both, in the tissue or organ. A reduced glucose concentration or a negative rate of change of glucose concentration in the tissue or organ as compared to a control glucose concentration or rate of change indicates ischemia in the tissue or organ. | 11-04-2010 |
20120009612 | METHOD TO DETECT AND MONITOR COMPARTMENT SYNDROME - Disclosed is a method of detecting and/or monitoring ischemia in a muscle tissue or compartment. The method includes the steps of measuring in real time or near-real time interstitial glucose concentration, or rate of change of interstitial glucose concentration over time, or both, in the muscle tissue or compartment. A reduced glucose concentration or a negative rate of change of glucose concentration in the tissue or compartment as compared to a control glucose concentration or rate of change indicates ischemia in the muscle or compartment. | 01-12-2012 |
