Abstract

An apparatus, such as a pressure support ventilator or respiratory monitor, provides operations for a patient, such a patient with heart failure, Chronic Obstructive Pulmonary Disease or other respiratory insufficiency. In some embodiments, the apparatus may detect a respiratory condition, such as a decompensation event and/or exacerbation event, from respiratory parameters. A clinical alert message may be transmitted or displayed for a physician based on the results of query presented to the patient in response to an analysis of the one or more respiratory parameters. In some embodiments, the apparatus generates a potential relapse indicator that may provide a prediction of a risk of an oncoming clinical event such as for evaluating whether to release the patient from a hospital.

First claim

1 . A monitoring system comprising:
at least one sensor configured to measure at least one respiratory parameter; a flow generator configured to generate a flow of breathable gas at a pressure above atmospheric pressure at a user interface; and a controller, communicatively coupled to the at least one sensor and the flow generator, the controller being configured to:
perform an evaluation of the at least one respiratory parameter during one or more monitoring sessions;
generate for display an indicator based on the performed evaluation of the at least one respiratory parameter, the indicator representing a prediction of future relapse; and
control the flow generator based on the performed evaluation of the at least one respiratory parameter.

2 . The system of claim 1 , wherein the at least one respiratory parameter comprises a measure of ventilation.

3 . The system of claim 1 , wherein the at least one respiratory parameter comprises a frequency of sleep disordered events.

4 . The system of claim 1 , wherein performing the evaluation of the at least one respiratory parameter comprises assessing a change in the at least one respiratory parameter over the one or more monitoring sessions.

5 . The system of claim 1 , wherein the indicator is a probability of a relapse occurring.

6 . The system of claim 1 , wherein the indicator is a Boolean-valued indicator.

7 . The system of claim 6 , wherein generating the indicator comprises comparing changes in the at least one respiratory parameter with one or more respective thresholds.

8 . The system of claim 1 , wherein the controller is further configured to display the indicator on a display.

9 . The system of claim 1 , wherein the sensor is a contactless motion sensor configured to use signals reflected from a user of the flow generator to measure the at least one respiratory parameter.

10 . A method of monitoring a user, the method comprising:
measuring at least one respiratory parameter with at least one sensor; generating a flow of breathable gas with a flow generator at a pressure above atmospheric pressure at a user interface; performing an evaluation of the at least one respiratory parameter during one or more monitoring sessions with a controller communicatively coupled to the at least one sensor and the flow generator; generating an indicator for display with the controller based on the performed evaluation of the at least one respiratory parameter, the indicator representing a prediction of future relapse of the user; and controlling the flow generator with the controller based on the performed evaluation of the at least one respiratory parameter.

11 . The method of claim 10 , wherein performing the evaluation of the at least one respiratory parameter comprises assessing a change in the at least one respiratory parameter over the one or more monitoring sessions.

12 . The method of claim 10 , wherein the indicator is a probability of a relapse occurring.

13 . The method of claim 10 , wherein the indicator is a Boolean-valued indicator.

14 . The method of claim 13 , wherein generating the indicator comprises comparing changes in the at least one respiratory parameter with one or more respective thresholds.

15 . The method of claim 10 further comprising:
displaying the indicator on a display.

16 . The method of claim 10 , wherein the sensor is a contactless motion sensor configured to use signals reflected from a user of the flow generator to measure the at least one respiratory parameter.

17 . A computer-readable medium storing program instructions configured to cause a processor to carry out a method of monitoring cardio-pulmonary health of a patient, the method comprising:
measuring at least one respiratory parameter with at least one sensor; generating a flow of breathable gas with a flow generator at a pressure above atmospheric pressure at a user interface; performing an evaluation of the at least one respiratory parameter during one or more monitoring sessions with a controller communicatively coupled to the at least one sensor and the flow generator; generating an indicator for display with the controller based on the performed evaluation of the at least one respiratory parameter, the indicator representing a prediction of future relapse of the user; and controlling the flow generator with the controller based on the performed evaluation of the at least one respiratory parameter.

18 . The computer-readable medium of claim 17 , wherein performing the evaluation of the at least one respiratory parameter comprises assessing a change in the at least one respiratory parameter over the one or more monitoring sessions.

19 . The computer-readable medium of claim 17 , wherein the method further comprises displaying the indicator on a display.

20 . The computer-readable medium of claim 17 , wherein the sensor is a contactless motion sensor configured to use signals reflected from a user of the flow generator to measure the at least one respiratory parameter.
