Abstract
A gas therapy system (1) has a flow line (3, 2), a coupler (6) to a gas source, and an aerosol generator (4) for aerosol delivery, and a patient interface such as a nasal interface (2). A controller (10) is configured to modulate gas flow and aerosol delivery in real time. The controller changes gas flow rate and dynamically reduces aerosol delivery during upper gas flow rates such as 60 LPM, and activates aerosol delivery during lower gas flow rates of for example 10 LPM. The control may also include sensors to detect breathing, so that there is a bias towards increased aerosol delivery during inhalation in addition to during lower level gas flow.
Claims22
A gas therapy system comprising a flow line, a gas source or a link to a gas source, and a nebulizer or a link to a nebulizer for aerosol delivery, a patient interface or a coupler for connection to a patient interface, and a controller configured to modulate gas flow and aerosol delivery in real time,
- wherein the controller is configured to change gas flow rate from the gas source between at least one upper level and at least one lower level, and to dynamically stop or reduce aerosol delivery from the nebulizer during gas flow at the upper level, and to dynamically activate or increase aerosol from the nebulizer during intervals of gas flow at the lower level,
- wherein the controller is configured to perform modulation of oxygen supplied during the intervals to maintain a desired patient blood oxygenation, and wherein the system includes a real time pulse oximeter and an oxygen regulator to perform said modulation.
A method of operation of a controller of a gas therapy system comprising a flow line, a gas source or a link to a gas source, and a nebulizer or a link to a nebulizer for aerosol delivery, and a patient interface or a coupler for connection to a patient interface,
- the method comprising steps of the controller modulating gas flow and aerosol delivery in real time, in which the controller changes gas flow rate from the gas source between at least one upper level and at least one lower level, and dynamically stops or reduces aerosol delivery from the nebulizer during gas flow at the upper level, and dynamically activates or increases aerosol delivery from the nebulizer during intervals of gas flow at the lower level,
- wherein the controller is configured to perform modulation of oxygen supplied during the intervals to maintain a desired patient blood oxygenation.
A gas therapy system comprising a flow line, a gas source or a link to a gas source, and a nebulizer or a link to a nebulizer for aerosol delivery, a patient interface or a coupler for connection to a patient interface, and a controller configured to modulate gas flow and aerosol delivery in real time,
- wherein the controller is configured to change gas flow rate between at least one upper level and at least one lower level, and to dynamically stop or reduce aerosol delivery during gas flow at the upper level, and to dynamically activate or increase aerosol delivery during intervals of gas flow at the lower level, and
- wherein the controller is configured to perform modulation of oxygen supplied during the intervals to maintain a desired patient blood oxygenation.
