20100113960 | Method and system for jointly monitoring physiological conditions - A method for providing an indication of a state of awareness for a patient, includes the steps of arranging data of an EEG and EMG power spectrogram to provide power versus frequency in a log-log arrangement; calculating a first best-fit line for a lower frequency region of the EEG power spectrogram; calculating a second best-fit line for a higher frequency region of the EEG power spectrogram; calculating a third best-fit line for the EMG power spectrogram; and displaying an indication of the state of awareness based on the first, second and third best-fit lines. | 05-06-2010 |
20110118620 | Method and system for monitoring and displaying physiological conditions - A method for providing an indication of a state of awareness for a patient, includes the steps of arranging data of an EEG and EMG power spectrogram to provide power versus frequency in a log-log arrangement; calculating a first best-fit line for a lower frequency region of the EEG power spectrogram; calculating at least a second best-fit line for a higher frequency region of the EEG power spectrogram. The display of these lines is augmented by displaying a template that identifies different regions on the display that help confirm the state of the patient. Secondly, the time domain EEG signals can be filtered and displayed such that different frequency bands can be simultaneously displayed or a single frequency band can be displayed according to different time scales. | 05-19-2011 |

20130253362 | METHOD AND SYSTEM FOR MONITORING AND DISPLAYING PHYSIOLOGICAL CONDITIONS - A system and method is used for determining from EEG signals the lack of awareness and the depth of anesthesia of a patient to whom an anesthetic agent is being administered. In particular, a log-log representation of the EEG power spectrum of a current patient is compared to another log-log spectrum of a patient in a known condition. By comparison the awareness or depth of anesthesia of the current patient can be determined. The reference spectrum can be an average spectrum of many patients or a previously acquired spectrum of the current patient, or any other spectrum that can be statistically correlated with the current patient's spectrum. | 09-26-2013 |

20150126890 | METHOD AND SYSTEM FOR MONITORING AND DISPLAYING PHYSIOLOGICAL CONDITIONS - Providing an indication of a state of awareness for a patient includes acquiring an EEG signal; filtering the EEG signal to generate a first frequency band of signals; and filtering the EEG signal to generate a second frequency band of signals. Providing the indication also includes concurrently displaying the first and second frequency bands of signals in a single display window such that at least a first portion of the first frequency band overlaps, spatially the second frequency band. | 05-07-2015 |
20150126891 | METHOD AND SYSTEM FOR MONITORING AND DISPLAYING PHYSIOLOGICAL CONDITIONS - Providing an indication of a state of awareness for a patient includes arranging data of an EEG power spectrogram to provide power versus frequency in a log-log arrangement; calculating a first best-fit line for a lower frequency region of the EEG power spectrogram, using a processor; and calculating a second best-fit line for a higher frequency region of the EEG power spectrogram. Also, a display device is used to display a density spectral array of the spectrogram using a display scale that ranges between an upper limit and a lower limit, wherein the lower limit is set based on one of the first best-fit line and the second best-fit line. | 05-07-2015 |
