  • Patent number: 11173262
    Abstract: The disclosure provides a way to supplement the tidal volume delivered to the patient by a leaking re-breather when the delivered volume becomes less than that set by the ventilator (in either pressure-regulated or volume modes). This may be accomplished with a shunt—a gas conduit joining the non-patient side of the re-breather to the patient side. A low-resistance, plenum or a draw-over vaporizer may also be incorporated into the gas pathway. Such a device may include a housing with a movable partition separating an actuating side from a patient side. The housing includes a ventilator orifice for pneumatic communication between a ventilator and the actuating side and a patient orifice for pneumatic communication between the patient side and a patient. A shunt defines a bypass flow path from the actuating side and to the patient side when the moveable partition is at a maximal displacement towards the patient side.

  • Patent number: 11173264
    Abstract: A program for controlling a respiratory assistance device that is connected to a user's airway and regulates an airway pressure to assist ventilation has a plurality of different respiratory assistance modes. The respiratory assistance program causes a computer to realize an input reception function that receives an input of setting for a respiratory assistance mode during operation of an air blower that blows air to the user's airway, and a flow rate control function that, when the input reception function receives the input of setting, controls a flow rate from the air blower in reflection of a result of the input of setting. A respiratory assistance device in which a user can change setting to select a comfort pressure and flow rate is provided by using such a program.

  • Patent number: 11154672
    Abstract: Systems and methods may include a gas source, a gas delivery circuit, and a nasal interface allowing breathing ambient air through the nasal interface. A gas flow path through the nasal interface may have a distal gas flow path opening. A nozzle may be associated with a proximal end of the nasal interface a distance from the distal end gas flow path opening. At least a portion of an entrainment port may be between the nozzle and the distal end gas flow opening. The nozzle may deliver gas into the nasal interface to create a negative pressure area in the gas flow path at the entrainment port. The nasal interface and the nozzle may create a positive pressure area between the entrainment port and the distal end gas flow path opening. Gas from the gas delivery source and air entrained through the entrainment port may increase airway pressure or lung pressure or provide ventilatory support.

  • Patent number: 11141553
    Abstract: A patient ventilation system includes a ventilator configured to deliver ventilation gas to patient, a CO2 concentration sensor configured to provide EtCO2 measurements for the patient, and an SpO2 monitor configured to determine an SpO2 value for the patient. A ventilation control module is executable on a processor and configured to compare the SpO2 value to a threshold SpO2 and determine from this comparison that the SpO2 value indicates inadequate oxygenation. A minimum ventilation amount is then set, and the ventilator is then controlled based on the EtCO2 measurements and the minimum ventilation amount so as to deliver at the least the minimum ventilation amount to the patient while the SpO2 value indicates inadequate oxygenation.
