Method and apparatus for detecting and treating heart failure

摘要

Devices and systems provide methods of detecting a heart failure condition of a patient that may be based on one or more respiratory parameters of a patient. In an example embodiment, a monitoring device determines one or more heart failure condition indicators based on a measure of the patient respiratory airflow and/or a measure of treatment pressure. Respiratory parameters such as respiration rate, hypopneas, apneas, Cheyne-Stokes breathing patterns or apnea-hypopnea counts may be compared to thresholds that are selected to represent a change in the condition of a heart failure patient such as an onset of a decompensation event. Results of the comparisons may trigger a pressure treatment change and/or one or more warnings or messages to notify a patient or physician of a pending change to the patient's heart failure condition so that the patient may more immediately seek medical attention to treat the heart failure condition.

主权项

1. A device for monitoring a patient to evaluate a heart failure condition of a patient comprising:
a patient interface; a non-invasive sensor to generate a signal associated with a characteristic of patient respiration; and a processor, coupled with the sensor, the processor configured to control and store a determination of a heart failure condition change indicator based on the signal, compare previously stored and determined values of the indicator from one or more previous treatment sessions and determine a risk of a heart failure decompensation event occurring for the patient based on the comparison, wherein the processor is further configured to trigger a heart failure decompensation risk message based on the comparison.
