Abstract
A method of determining a duration of safe apnoea. Information is obtained relating to a respiratory indicator, which can include information relating to a potential respiratory equilibrium, and a duration of safe apnoea is determined from the obtained information.
Claims21
A respiratory therapy system comprising:
- a flow generator for providing a gases flow to a patient;
- at least one processor in electronic communication with the flow generator, the at least one processor provided with instructions which, when implemented, cause the at least one processor to:
- receive one or more physiological parameters associated with the patient;
- calculate a predicted apnoeic respiratory equilibrium value of the patient based on the one or more physiological parameters, wherein the predicted apnoeic respiratory equilibrium value is an oxygen saturation value where an oxygen saturation of haemoglobin in the patient is predicted to be at a stable level for a period of time during apnoeic oxygen delivery to the patient;
- and
- cause the flow generator to control the gases flow to the patient based at least in part on the predicted apnoeic respiratory equilibrium value;
- and
- an electronic display which receives an output from the at least one processor and displays one or more properties associated with the predicted apnoeic respiratory equilibrium value.
