Claim Text:
1. An apparatus for treating a patient with heart failure comprising: a blower configured for supplying a controllable level of breathable gas to a mask at a pressure above atmospheric wherein the mask provides a sealable connection with the patient's airway; a differential pressure transducer configured to generate a flow signal representative of the patient's airflow; and a processor configured to receive said flow signal and control said level of breathable gas; wherein said apparatus comprises programmed control instructions to control a determination of a heart failure indicator indicative of a degree of heart failure of the patient from said flow signal, and wherein the apparatus further comprises programmed control instructions to analyze said heart failure indicator to determine a change in said heart failure indicator over time, wherein said change is a difference between a previous heart failure indicator and a subsequent heart failure indicator, wherein the apparatus further comprises programmed control instructions to control beginning of subsequent heart failure treatment based at least in part upon said change in said heart failure indicator, wherein said subsequent heart failure treatment comprises an increase in pressure.
