  • Patent number: 10821247
    Abstract: A ventilator (1) determines states with cough attacks and an operating method for a ventilator determines cough attacks. It is determined on the basis of pressure measured values (13, 21, 19) and flow measured values (11, 15, 17) whether consecutive elevations of an airway pressure in a ventilator (1) are due to one cough event or due to a plurality of cough events. A plurality of cough events indicates a state of a cough attack. An output (41, 42, 44) of a warning (44) or alarm (42) is issued indicating the state.

  • 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.

    Abstract: A ventilator system and method can deliver artificial respirations to a person receiving cardiopulmonary resuscitation. The system and method may provide intermittent breath delivery (e.g., with interruptions), so that activation of the device gives a specific predetermined number of breaths, interspersed with a set time period of no breath. This pattern may be by default, manually triggered where one activation gives a set number of breaths followed by a pause until the next activation for breath (one activation gives one breath cycle), or one activation results in continuous cycle of intermittent breaths). In some embodiments, a signaling mechanism may deliver signals to a rescuer relating to timing of chest compressions of the person. The timing of the chest compressions for the signals may be based on a time of delivery of the artificial respirations. In certain embodiments, different sized masks each include a gas flow restrictor which is unique for the size of mask.

  • Patent number: 10384025
    Abstract: A pressure support system configured to deliver a pressurized flow of breathable gas to the airway of a subject is described. The system is configured to treat obstructive sleep apnea, other sleep disordered breathing, and/or other respiratory issues with limited flow respiration therapy, and/or other therapies. Limited flow respiration therapy may be an alternative to CPAP, for example. The system is configured to limit flow rate compensation, pressure compensation, and/generator or compensation of other parameters during inspiration to values proportional to the current leak to achieve limited flow respiration therapy. In some embodiments, the system comprises one or more of a pressure generator, a subject interface, one or more sensors, a processor, a user interface, electronic storage, and/or other components.

  • Patent number: 10383569
    Abstract: A method for controlling operation of a CPAP apparatus. The apparatus has a blower, a patient interface, an air delivery conduit for delivering air from the blower to the patient interface, a sensor for determining the pressure in the patient interface, and a control mechanism that causes air to be delivered at a desired pressure to the patient interface and that detects transitions between inhalation and exhalation of a respiratory cycle of a patient in order to synchronize the blower output with the patient's efforts. In one form the CPAP apparatus provides pressure in accordance with a bi-level waveform with at least one characterizing parameter of the waveform being automatically adjusted in accordance with indications of sleep disordered breathing. The indications of sleep disordered breathing can be one or more of snoring, apnea, hypopnea, and flow limitation.

  • Patent number: 10350379
    Abstract: A device (102) provides respiratory treatment for SDB (including mild OSA) and other respiratory conditions. A flow generator warms and humidifies gas at controlled flow levels. For example, the device (102) delivers breathable gas to the upper airway at flow rates of about 10-35 Liters/minute. Levels of flow rate, temperature and/or humidification of the device may be automatically adjusted in response to the detection of SDB events. The device may also automatically deliver adjustments of any of the levels in accordance with detected phases of respiratory cycles. In some embodiments, the device automatically delivers distinct levels to either of the nares based on independent control of flow to each nare. A warm-up procedure controls temperature and humidity at a desired target during a ramp-up of flow to the set therapy level. A cool-down procedure controls temperature above the dewpoint to avoid condensation internal to the device and patient interface.
