Claim 10:
11. A method for monitoring and treating respiratory distress in a patient, comprising:
acquiring patient condition signals indicative of a state of the respiratory distress using one or more non-invasive monitoring devices, the patient condition signals including a blood pressure signal indicative of a blood pressure of the patient, a cardiac signal indicative of cardiac cycles of the patient, and a respiratory signal indicative of inspiration and expiration phases of the patient; and
monitoring the state of the respiratory distress automatically using a non-invasive device including a respiratory distress monitoring circuit, the monitoring including:
processing the patient condition signals;
generating patient condition parameters indicative of the state of the respiratory distress using the processed patient condition signals, including generating a physical state parameter indicating a physical state of the patient including at least the inspiration and expiration phases using the respiratory signal and generating a baroreflex sensitivity (BRS) parameter being a measure of the BRS of the patient using the blood pressure signal and the cardiac signal;
stratifying the BRS parameter using the physical state parameter;
producing a patient condition metric being a linear or nonlinear function of the patient condition parameters including the BRS parameter stratified by values of the physical state parameter including the inspiration and expiration phases;
performing at least one of prediction or detection of an exacerbation of the respiratory distress based on the patient condition metric; and
producing an alert notifying a result of the performance of the at least one of prediction or detection.
