Abstract
Disclosed is a respiratory gas supply system comprising a respiratory gas source, a control unit, a pressure control module, a flow control module, a pressure sensor device, a flow sensor device and a user interface for the specification of respiratory gas supply parameters or for the exchange of data. The control unit alternately activates the pressure control module and the flow control module, with the pressure control module controlling the respiratory gas source to specify a respiratory gas pressure in the range of 0-90 mbar and the flow control module controlling the respiratory gas source to specify a respiratory gas flow in the range of 0-90 l/min.
Claims20
A system for respiratory gas supply, wherein the system comprises a respiratory gas source, a control unit, a memory, a pressure control module, a flow control module, a pressure sensor device, a flow sensor device, a user interface for a specification of parameters of the respiratory gas supply or for an exchange of data, comprising a respiratory gas tube and a patient interface, and additionally comprises at least one humidifier and/or an oxygen source and/or a nebulizer and/or a heater, the control unit alternately activating the pressure control module or the flow control module, the pressure control module controlling the respiratory gas source so as to specify a respiratory gas pressure, and the flow control module controlling the respiratory gas source so as to specify a respiratory gas flow.
A system for respiratory gas supply, wherein the system comprises a respiratory gas source, a control unit, a memory, a pressure control module, a flow control module, a pressure sensor device, a flow sensor device, and a user interface for specification of parameters of the respiratory gas supply or for an exchange of data, comprising a respiratory gas tube and a patient interface, and further comprises at least a humidifier and a heater, the control unit alternately activating the pressure control module or the flow control module, the pressure control module controlling the respiratory gas source to specify a respiratory gas pressure and the flow control module controlling the respiratory gas source to specify a respiratory gas flow, the control unit additionally activating the humidifier and the heater for heating and humidifying the respiratory gas when the flow control module is activated.
