Means For Sensing Condition Of User's Body Patents (Class 128/204.23)
  • Patent number: 10773039
    Abstract: A system and a method for expiratory flow limitation (EFL) detection by controlling positive pressure (e.g., PEEP) applied during expiration for a subject is based on a temporary perturbation or adjustment of a pressure level of positive pressure during exhalation on selected breaths. The different responses to such a perturbation of flow-limited breaths compared to non-flow limited breaths is used to assess EFL in a subject. Automatic adjustments of the positive pressure applied to the patient are used in the disclosed algorithm to abolish EFL, and are implemented through existing ventilators and other respiratory devices.

  • Patent number: 10765359
    Abstract: Sensing circuitry of an implantable medical device (IMD) system may sense a cardiac signal that varies according to a cardiac cycle of a patient. Processing circuitry of the IMD system may determine a series of consecutive cardiac cycle length metric values based on the sensed cardiac signal, identify a plurality of pairs of the cardiac cycle length metrics, each of the pairs of cardiac cycle length metrics separated by an integer ‘n’ of the cardiac cycle length metrics, and construct a distribution of the pairs of cardiac cycle length metrics based on values of the cardiac cycle length metrics for each of the pairs. The processing circuitry may detect a sleep apnea episode of the patient based on one or more characteristics of the constructed distribution, and control communication circuitry of the IMD system to transmit an indication of the detected sleep apnea episode to the external computing device.

  • Patent number: 10722143
    Abstract: The present disclosure relates to determining a corrected exhaled gas measurement during high flow respiratory therapy. Measuring exhaled gas concentration during high flow respiratory therapy is difficult and inaccurate due to a phenomenon known as flushing. The high flows delivered to the patient flush the dead space in the conducting airways, which causes a dilution effect that results in underestimated or overestimated exhaled gas measurement depending on the gas composition delivered by the high flow system. This can lead to incorrect clinical measurements and diagnoses. Various algorithms are disclosed herein to account for the dilution effect caused by flushing, allowing for the method of measuring gas concentrations to still be used accurately for clinical measurements.

  • Patent number: 10449312
    Abstract: A method and apparatus for providing ventilatory assistance to a spontaneously breathing patient. An error signal is computed that is the difference between a function of respiratory airflow over a period of time and a target value. Using a servo loop, air is delivered to the patient at a pressure that is a function of the error signal, the phase of the current breathing cycle, and a loop gain that varies depending on the magnitude of the error signal. The loop gain increases with the magnitude of the error signal, and the gain is greater for error signals below a ventilation target than for error signals above the ventilation target value. The target value is an alveolar ventilation that takes into account the patient's physiologic dead space.

    Abstract: A ventilator control signaling method includes recording an electromyogram signal of values following one another in time and transforming the electromyogram signal into an evaluation signal by applying an evaluation function. An evaluation signal value is assigned to a signal value of the electromyogram signal in the transformation. The evaluation function is determined by a main parameter set that defines which signal value of the evaluation signal is assigned to a particular signal value of the electromyogram signal when the evaluation function is applied in the transformation. A signal value height of the evaluation signal indicates whether the electromyogram signal corresponds to a first state or a second state. A control signal is generated from signal values and is set to switch a ventilator to an inhalation or an exhalation operating mode depending on the state of the evaluation signal. A ventilator is configured to perform the method.

  • Patent number: 10232138
    Abstract: The present invention generally relates to systems and method for delivery of therapeutic gas to patients in need thereof using enhanced breathing circuit gas (BCG) flow measurement. At least some of these enhanced BCG flow measurements can be used to address some surprising phenomena that may, at times, occur when wild stream blending therapeutic gas into breathing gas that a patient receives from a breathing circuit affiliated with a ventilator. Utilizing at least some of these enhanced BCG flow measurements the dose of therapeutic gas wild stream blended into breathing gas that the patient receives from a ventilator can at least be more accurate and/or over delivery of therapeutic gas into the breathing gas can be avoided and/or reduced.

  • Patent number: 10219739
    Abstract: What is disclosed is a system and method for identifying a patient's breathing pattern for respiratory function assessment without contact and with a depth-capable imaging system. In one embodiment, a time-varying sequence of depth maps are received of a target region of a subject of interest over a period of inspiration and expiration. Once received, the depth maps are processed to obtain a breathing signal for the subject. The subject's breathing signal comprises a temporal sequence of instantaneous volumes. One or more segments of the subject's breathing signal are then compared against one or more reference breathing signals each associated with a known pattern of breathing. As a result of the comparison, a breathing pattern for the subject is identified. The identified breathing pattern is then used to assess the subject's respiratory function. The teachings hereof find their uses in an array of diverse medical applications. Various embodiments are disclosed.

  • Patent number: 10207071
    Abstract: A nasal cannula arrangement for use as part of systems for delivery respiratory gases to a patient is disclosed. The nasal cannula arrangement includes a manifold part adapted to receive gases from a delivery conduit. The manifold includes one but preferably a pair of prongs extending upward and curving towards the rear of the manifold. The prongs are inserted into the nostrils of the patient and deliver gases to a patient. The prongs have a cut out on the rear side of the prongs. The cut out forms a gases outlet in the prongs and are shaped such that the area of the cut out area is greater than the cross sectional area of the prongs at the entry point to the prongs.

  • Patent number: 10165959
    Abstract: An apparatus for use in diagnosing the presence of obstructive sleep apnea (OSA) in a patient includes a sensing module structured to measure a parameter indicative of a tremor in the patient's neck, tongue and/or throat muscles while the patient is awake, the parameter not being airflow through the patient's airway. The sensing module generates one or more electrical signals based on the measured parameter. The apparatus also includes a processor operatively coupled to the sensing module, the processor being structured to receive the one or more electrical signals, perform an analysis of the one or more electrical signals, and based on the analysis determine whether the tremor has a frequency in at least one predetermined frequency range that is indicative of OSA.
