Two-way communications in a medical device

A respiratory pressure therapy system for providing continuous positive air pressure (CPAP) to a patient, the respiratory pressure therapy system comprising:

• a flow generator configured to generate a supply of breathable gas for delivery to the patient, wherein the breathable gas is output from the flow generator at a pressure level that is above atmospheric pressure;
• at least one sensor that is configured to measure a physical quantity while the breathable gas is supplied to the patient;
• a computing device including memory and at least one hardware processor, the computing device configured to control the respiratory pressure therapy system to:
• before initial use of the respiratory pressure therapy system to provide a therapy to the patient:
• display, on a display device, one or more demographic questions relating to demographic information of the patient and a plurality of selectable responses to the one or more demographic questions;
• responsive to displaying the one or more questions, receive one or more inputs selecting of one or more of the selectable responses to the one or more demographic questions;
• display, on the display device, a first question relating to subjective feedback from the patient and a plurality of selectable responses to the first question;
• responsive to displaying the first question, receive a first input selecting one of the selectable responses to the first question;
• and
• in response to receiving the first input, display a first coaching response from among a plurality of coaching responses corresponding to the selected response to the first question, wherein each of the selectable responses to the first question relating to subjective feedback corresponds to a different coaching response from among the plurality of coaching responses;
• and
• during use of the respiratory pressure therapy system to provide therapy to the patient:
• receive, from the at least one sensor, sensor data that is based on measured physical property of the supply of breathable gas;
• and
• control, based on the received sensor data and the inputs selecting one or more of the selectable responses to the one or more demographic questions, the flow generator to adjust a property of the supply of breathable gas that is delivered to the patient.
