  • Patent number: 11179067
    Abstract: There is provided a biological state monitoring system for monitoring biological state of subject on a bed. The system includes at least one load detector and a controller. In a case that the controller determines that body motion is not twitch, the controller ceases to output estimated value of respiratory rate, or outputs first estimated value which is the latest among estimated values obtained in first period, the first period being directly preceding body motion and being determined by the controller to be a period in which subject has no body motion. In a case that the controller determines that body motion is twitch, the controller successively outputs newly obtained estimated values of respiratory rate.

    Abstract: The present invention relates to a system (10) and a corresponding method for estimating the respiratory drive (R_DRIVE) of mechanically ventilated patients, and for preferably apportioning this respiratory drive into one, or more, components related to the chemical drive—i.e. the drive due to the chemoreceptor response—and/or the muscular drive—i.e. the contraction of respiratory muscles, for example the diaphragm. The principle of the invention is that respiratory drive can be obtained from measuring the patient's response to small changes in mechanical ventilation settings (Vt_SET), and that this can be apportioned into chemical and/or muscular effects depending upon the changes in respiratory frequency, and/or arterial or end tidal CO2 levels, and/or arterial blood p H.

  • Patent number: 10974000
    Abstract: Methods and apparatus treat a respiratory disorder. For example, a pressure generator supplies a flow of air at positive pressure to a patient's airway through a patient interface. A sensor generates a signal representing respiratory flow rate of the patient. A controller controls the pressure generator to provide to the patient interface a ventilation therapy having a base pressure. The controller computes a measure of ventilation of the patient from the signal. The controller computes a measure of flow limitation from an inspiratory portion of the signal. The controller computes a ratio of the measure of ventilation and an expected normal ventilation. The controller adjusts a set point for the base pressure of the ventilation therapy based on the measure of flow limitation. The adjustment may further depend on a comparison between the ratio and a relative ventilation threshold that increases as the measure of flow limitation increases.

    Abstract: An additive gas delivery apparatus, system and method for delivery of additive gas, such as nitric oxide [NO], to a patient use a control computer configured to determine if a monitored parameter indicates that a patient is connected to the additive gas delivery apparatus, determine if the additive gas delivery apparatus is in a passive state in which it does not deliver additive gas, and activate an alarm if the additive gas delivery apparatus is in said passive state when the monitored parameter indicates that a patient is connected to the additive gas deliver apparatus. The alarm serves to notify the user of undesired non-delivery of additive gas, and so serves to improve safety in additive gas delivery systems.

  • Patent number: 10751490
    Abstract: Methods and apparatus provide automated circuit disconnection monitoring such as for a respiratory apparatus or system. Disconnection of a patient circuit, including a patient interface and air delivery circuit, may be detected and a message or alarm activated. In some versions, detecting occurrences of circuit disconnection event(s), such as by a processor, may be based on an instantaneous disconnection parameter as a function of a disconnection setting. The disconnection setting may be determined based on patient circuit type. The instantaneous disconnection parameter may be determined from detected pressure and flow rate, and may be, for example, a conductance value or an impedance value. Disconnection events may be qualified by one or more detected respiratory indicators.

  • Patent number: 10688263
    Abstract: A servoventilator control slowly changes the target ventilation over a period of time, according to a preprogrammed schedule adapted to be set by the physician. Preferably, the target ventilation stays constant at an initial target ventilation for an initial hold time, and then increases at a constant rate until it reaches a final target ventilation, whereupon it stays constant thereafter. If the pressure support level is too high, possibly indicating glottic or upper airway closure, the rate of increase of target ventilation may be lowered or the final target ventilation not reached.

  • Patent number: 10668234
    Abstract: A tool for use in conjunction with a pressure support system that is structured to provide therapy to a patient to treat a condition of the patient by delivering a flow of breathing gas to the patient. The tool may be implemented on a portable electronic device or a PC and is configured to, among other things, provide customized/personalized education and feedback to the patient based, at least in part, on data that is measured by the pressure support system during the provision of therapy to the patient. The tool utilizes certain patient/therapy metrics, wherein each patient/therapy metric comprises raw data that was measured by the pressure support system and that has been processed (e.g., summarized and/or otherwise manipulated) to form the patient/therapy metric.

  • Patent number: 10661037
    Abstract: A method, connector and system for obtaining an indirect measurement of a parameter in a patient with a total liquid ventilation (TLV) system. At least one parameter measurement is obtained of a liquid taken in the TLV system comprising an endotracheal tube having a distal end inserted in a patient's trachea. At least one flow measurement is obtained of a liquid taken in the TLV system. Considering a fluid model of the TLV system, the at least one parameter measurement and the least one flow measurement are processed into the indirect measurement of the parameter in the patient. The indirect measurement may be a temperature or pressure. The temperature can be a lung temperature, a blood temperature or an organ temperature. The pressure may be a tracheal pressure or an alveolar pressure.

  • Patent number: 10646683
    Abstract: The present invention provides a method for reducing condensed humidifying agent in a humidification system by pulsing a delivery of humidifying agent into a respiratory circuit. During a non-pulsed interval, gas flowing through the respiratory circuit will evaporate the condensed humidifying agent present in the respiratory circuit. The present invention also provides a method and apparatus for delivering humidified gas to a patient, wherein the delivery avoids the problems associated with a stationary water humidifier. In the method, the delivery of humidifying agent is precisely controlled to deliver a flow of humidifying agent to a volume of gas.
