Embodiments of the present disclosure provide systems and methods for monitoring a patient to produce a signal representing a blood oxygen concentration. The signal may be analyzed to determine the presence of one or more sleep apnea events, and an integral of the signal may be calculated if the signal is outside of a set range or threshold. A practitioner may choose to be informed of the presence of sleep apnea events if the blood oxygen concentration is less then a preset limit, if an upper limit has been reached for an integral representing the severity of the oxygen deprivation over time, or anytime sleep apnea events may be present in the signal.

Methods and systems for alerting practitioners to physiological conditions

Present embodiments are directed to a system and method capable of detecting and graphically indicating physiologic patterns in patient data. For example, present embodiments may include a monitoring system that includes a monitor capable of receiving input relating to patient physiological parameters and storing historical data related to the parameters. Additionally, the monitoring system may include a screen capable of displaying the historical data corresponding to the patient physiological parameters. Further, the monitoring system may include a pattern detection feature capable of analyzing the historical data to detect a physiologic pattern in a segment of the historical data and capable of initiating a graphical indication of the segment on the screen when the physiologic pattern is present in the segment.

System and method for facilitating observation of monitored physiologic data

Embodiments disclosed herein may include systems and methods for reducing power consumption of a pulse oximeter. The disclosure describes method for measuring oxygen saturation of a patient's blood with a pulse oximeter that switches between a high power mode of operation and one or more low power modes of operation based at least in part upon the data obtained from the patient or otherwise generated by the pulse oximeter. In one embodiment, the disclosure describes a operating a pulse oximeter in a high power mode, the pulse oximeter using a sensor to generate data indicative of the oxygen saturation of the patient's blood at a first resolution and switching the pulse oximeter to a low power mode upon detection of data indicative of a non-critical situation. The low power mode may be selected from a set of available low power modes based at least in part upon the data generated by the pulse oximeter.

Pulse oximeter with adaptive power conservation

Various embodiments may provide methods and systems capable of evaluating physiological parameter data. The methods and systems may include monitoring a patient to produce a signal comprising a sequence of numerical values for blood oxygen saturation over a time period. The signal may be analyzed to identify two or more desaturation patterns within the time period, and at least two numerical differences are calculated between the desaturation patterns. A saturation pattern detection index may be calculated using the numerical differences between the desaturation patterns. The saturation pattern detection index may be used to provide an indication of a physiological condition. Other embodiments may provide a medical device that may be used to evaluate physical parameter data according to the techniques described.

The present disclosure may provide a system and method for analyzing data acquired using a physiological monitor. In one embodiment, the analysis is performed on the physiological monitor and results in the analysis of data collected by the physiological monitor over an interval of time. The analysis may include comparing the data to sample data representative of known disease states and/or may include performing statistical analyses or recalculations of the data based on adjusted monitor settings. In one embodiment, the settings of the physiological monitor may be adjusted based on the results of the analyses.

System and method for enabling a research mode on physiological monitors

Embodiments disclosed herein may include systems and methods for evaluating physiological parameter data. Embodiments of methods may include monitoring a patient to produce a signal comprising a sequence of numerical values for a physiological parameter over a time period, calculating an index from the signal, comparing the index to a reported index, and if the index is greater than the reported index, setting the reported index to the value of the index. Embodiments of methods may include calculating a modulation of the signal, comparing the modulation to a previous value of the modulation to identity a trend in the modulation and if the trend corresponds to an undesirable condition, using a first function to increase the reported index. Embodiments of methods may include providing an indication of a physiological status based on the reported index.

System and method for evaluating physiological parameter data

The methods and systems may include a receiver capable of collecting a signal representative of a physiological status of a patient, a plurality of data analysis components, wherein each of the plurality of data analysis components is capable of generating a metric based on the signal, and an arbitrator communicatively coupled to each of the plurality of data analysis components and capable of generating a single metric from the metrics generated by the plurality of data analysis components.

System and method for diagnosing sleep apnea based on results of multiple approaches to sleep apnea identification

Present embodiments are directed to a system and method capable of detecting and graphically indicating physiologic patterns in patient data. For example, present embodiments may include a monitoring system that includes a monitor capable of receiving input relating to patient physiological parameters and providing indications or alarms related to oxygen saturation declines and oxygen desaturation patterns associated with sleep apnea. Present embodiments may include methods and systems for mediating between alarms and other indicators associated with oxygen desaturation and ventilatory instability.
