Methods and apparatus for detecting and treating respiratory insufficiency
First Claim
1. A device for monitoring a patient to evaluate a respiratory insufficiency condition of the patient comprising:
- a transducer to generate a signal representative of a pressure delivered by a flow generator; and
a processor, coupled with the transducer, the processor configured to control an evaluation of a severity change indicator based on detecting, using a measure of determined pressure from the signal, a change in the measure of determined pressure from a plurality of treatment sessions, the evaluation comprising a detection of a continuous rise in the measure of determined pressure successively through the plurality of treatment sessions, the indicator representing information about a change in severity of a respiratory insufficiency condition of the patient,wherein the respiratory insufficiency condition is attributable to an insufficiency condition of the patient'"'"'s lungs.

Abstract
Devices and systems provide methods of detecting a severity change in respiratory insufficiency (RI) or chronic obstructive pulmonary disease (COPD) condition of a patient. In an example embodiment, a detection monitoring device determines one or more severity change indicators based on a measure of supplied pressure or other representative measure determined by the device. The supplied pressure may optionally be determined during pressure treatment that satisfies a target ventilation. The supplied pressure or representative data may be compared to one or more thresholds that are selected to represent a change in the condition of the RI or COPD patient such as an exacerbation of a prior condition. Results of the comparisons may trigger one or more warnings or messages to notify a patient or physician of a pending change to the patient'"'"'s RI or COPD condition so that the patient may more immediately seek medical attention to treat the condition.
