The present disclosure pertains to a pressure support system configured to adjust a pressurized flow of breathable gas delivered to a subject. The system is configured to simplify adjustments to humidity and/or temperature control and/or pressure support therapy that enhance the comfort level of the subject during therapy. The system is configured to generate output signals and/or determine various parameters related to the pressurized flow of breathable gas. The system is configured to receive feedback from the subject related to a comfort level of the subject during therapy and automatically adjust the pressurized flow of breathable gas and/or the predetermined therapy regime, provide feedback to the subject, and/or prompt the subject to make manual adjustments based on the output signals, the determined parameters, the feedback, and/or other information.

Provided is a method that includes automatically providing air/oxygen at a pre-selected maximum pressure limit, breath volume and respiratory-rate. The pre-selected maximum pressure limit, breath volume, and respiratory-rate are automatically set as a function of a size of a mask coupled to an air/oxygen supply system. Further provided is a ventilator system that includes a ventilator mask, a ventilator supply system, and a mask conduit. The ventilator mask is configured in a size that will fit upon a selected range of sizes of human faces. The ventilator supply system includes an air/oxygen source and an air/oxygen regulator system configured to regulate air/oxygen flow parameters as a function of the size of the mask. The mask conduit is configured to couple the ventilator supply to the ventilator mask.

An example aerosol delivery device includes a mouthpiece having an airflow outlet, and an airflow passage extending between an airflow inlet and the airflow outlet. The example aerosol delivery device further includes a housing configured to receive a cartridge that includes an aerosolizable substance and a vapor element configured to heat the aerosolizable substance, and an internal power source configured to provide electrical power. The example aerosol delivery device further includes a controller coupled to the internal power source to receive a portion of the electrical power and configured to, when the cartridge is installed at the housing, cause the vapor element of the cartridge to heat the aerosolizable substance to release an aerosol into the airflow passage during an inhalation through the airflow outlet, and a connector configured to receive power from an external source to recharge the internal power source.

A valve assembly, a ventilator, a process for operating a valve assembly and a computer program are provided. The valve assembly (10; 10a; 10b), for the ventilator (100), includes an inlet (12; 12a; 12b) configured for the inflow of a ventilation gas, an outlet (14; 14a; 14b) configured for the outflow of the ventilation gas and a volume flow control device (16; 16a; 16b) for the ventilation gas between the inlet and the outlet. The volume flow control device is configured to set the volume flow of the ventilation gas in a range between shut-off and a maximum volume flow and to provide an attenuation of a volume flow change during the opening, when the volume flow of the ventilation is increased, that differs from an attenuation occurring during the closing, when the volume flow of the ventilation gas is reduced.

The embodied invention is a new inspiration/expiration ventilator flow design, with a constant inspiration flow and intermittent-concurrent expiratory flow based on lung pressure setpoints. This mode is possible by using a new dual lumen tube inserted into a patient Trachea. Additionally, the control provides support for patient initiated breathing which is initiated by a lung pressure drop. This control provides continuous and gentle recruitment of lung alveoli.

Therapy gas delivery systems that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

An inspiratory resistor valve system (IRV) to regulate intrathoracic pressure during positive pressure breathing, spontaneous inspirations, and CPR may include an inspiratory port. The IRV system may include patient port. The IRV system may include a separate expiratory port. The IRV may include a plurality of atmospheric pressure sensitive valves. The plurality of atmospheric pressure sensitive valves may isolate the expiratory port and the inspiratory port from one another.

A breathing assistance device includes a gas regulating valve. The gas regulating valve is operated by a linear actuator. The linear actuator may include a movable member that moves an obstruction member between an open position and a closed position. The linear actuator is isolated from a gas flow path through the valve.

An apparatus to administer drugs to mechanically ventilated patients includes a mechanical ventilator, an artificial airway to be associated to a patient and a ventilation circuit connecting the mechanical ventilator to the artificial airway. The ventilation circuit includes: an inspiratory line, a dry powder inhaler disposed in line on the inspiratory line and a connector operatively connected to the dry powder inhaler and to the inspiratory line. The connector includes: a first duct facing an outlet port of the dry powder inhaler and connected or configured to be connected to a tube section of the inspiratory line placed downstream the dry powder inhaler; a second duct facing an air inlet port of the dry powder inhaler and connected or configured to be connected to a tube section of the inspiratory line placed upstream the dry powder inhaler.
