Abstract
Respiratory systems with a flow generator can provide bubble CPAP therapy by controlling the pressure of a flow of gas delivered to a patient. The controller of the respiratory system can control a motor speed of its flow generator so as to control the pressure of the flow of gas. The controller can also detect presence of bubbling and/or possible leaks in the gas pathway of the system. The respiratory system can include a high flow respiratory system.
Claims18
A respiratory system which is programmed to deliver both a high flow therapy and a bubble CPAP therapy, wherein the respiratory system comprises:
- a flow generator;
- a humidifier in fluid communication with the flow generator;
- an inspiratory conduit in fluid communication with the humidifier;
- and
- a controller configured to control the flow generator to provide the high flow therapy and the bubble CPAP therapy, the controller changeable between the high flow therapy and the bubble CPAP therapy;
- wherein the controller is further configured to detect bubbling of a bubbler by monitoring a variation in a flow parameter signal, and wherein in response to the controller detecting bubbling, the controller is configured to output an indication that bubbling is detected or select or switch to the bubble CPAP therapy.
