  • Patent number: 10661038
    Abstract: Automated methods provide hypopnea detection for determining a hypopnea event and/or a severity of a hypopnea event. In some embodiments, a calculated short-term variance of a measured respiratory flow signal are compared to first and second proportions of a calculated long-term variance of the measured flow signal. A detection of the hypopnea may be indicated if the first measure falls below and does not exceed a range of the first and second proportions during a first time period. In some embodiments, a hypopnea severity measure is determined by automated measuring of an area bounded by first and second crossings of a short-term measure of ventilation and a proportion of a long-term measure. The detection methodologies may be implemented for data analysis by a specific purpose computer, a detection device that measures a respiratory airflow or a respiratory treatment apparatus that provides a respiratory treatment regime based on the detected hypopneas.

  • Patent number: 10660563
    Abstract: Methods and apparatus monitor health by detection of sleep stage. For example, a sleep stage monitor (100) may access sensor data signals related to bodily movement and/or respiration movements. At least a portion of the detected signals may be analyzed to calculate respiration variability. The respiration variability may include one or more of variability of respiration rate and variability of respiration amplitude. A processor may then determine a sleep stage based on one or more of respiration variability and bodily movement, such as with a combination of both. The determination of sleep stages may distinguish between deep sleep and other stages of sleep, or may differentiate between deep sleep, light sleep and REM sleep. The bodily movement and respiration movement signals may be derived from one or more sensors, such as non-invasive sensor (e.g., a non-contact radio-frequency motion sensor or a pressure sensitive mattress).

  • Patent number: 10631738
    Abstract: A method and system for the analysis of a patient's oximetry data to detect sleep-disordered breathing is provided. The system employs an algorithm to reliably detect patient arousals and correlate those with accelerated heart rate and oxygen saturation levels in a manner that detects sleep-disordered breathing via the respiratory mask. Initially a timing channel is formed based on a plethsmography signal using an optical finger sensor. Based on the pleth waveform, a respiratory wave form is prepared that represents respiration rate. An arousal mask is applied to the signal based on attenuations in the pleth signal. Once arousals are identified the time required for changes to propagate from the lungs to the blood gas is subtracted from the onset time of the arousal. As a result if the timing agrees with dropping oxygen saturation or falling arterial pH then the arousal is indicated as a chemoreflex related arousal.

  • Patent number: 10332379
    Abstract: A data collection system collects and stores physiological data from an ambulatory patient at a high resolution and/or a high data rate (“more detailed data”) and sends a low-resolution and/or downsampled version of the data (“less detailed data”) to a remote server via a wireless network. The server automatically analyzes the less detailed data to detect an anomaly, such as an arrhythmia. A two-tiered analysis scheme is used, where the first tier is more sensitive and less specific than the second tier. If the more sensitive analysis detects or suspects the anomaly, the server signals the data collector to send more detailed data that corresponds to a time period associated with the anomaly. The more specific second tier analyzes the more detailed data to verify the anomaly. The server may also store the received data and make it available to a user, such as via a graphical or tabular display.

  • Patent number: 10226199
    Abstract: An information processing apparatus includes an acquisition unit, a specification unit, a determination unit, a generation unit, and a display control unit. The acquisition unit acquires a three-dimensional image containing at least a tubular structure. The specification unit specifies a first point inside the tubular structure and specifies a lesion outside the tubular structure in the three-dimensional image. The determination unit determines whether a blood vessel is present in a region between the first point and the lesion based on signal values of voxels of the three-dimensional image in the region between the first point and the lesion. The generation unit generates a two-dimensional image of the tubular structure viewed from the first point based on the three-dimensional image. The display control unit displays information indicating a region of the lesion on the two-dimensional image to be distinguishable in determining whether a blood vessel is present in the region.

  • Patent number: 10168316
    Abstract: A method and apparatus for measuring endogenous CO concentration in exhaled alveolar air, comprises: proposing a method for injecting samples in small amounts, multiple times, intermittently, and establishing a CO concentration relationship between sample gas and gas in a measuring chamber; establishing a “concentration difference/electrical level difference” difference value fitting method, to obtain a fitted standard curve for a difference value between the sample gas and base gas; establishing an apparatus for measuring a CO concentration difference and a CO2 concentration difference between sample gas and base gas; proposing a method for compensating a measurement value for endogenous CO in exhaled alveolar air. The problem that the amount of sample gas in a breath test is small, and cannot completely replace the gas originally inside the measuring chamber, is solved. The effect of electrical level zero drift and residual CO of unknown concentration in cleaning gas is eliminated.
