A system and method are implemented to identify pulmonary congestion in a subject. The system and method detect pulmonary congestion in a subject based on one or more parameters of the breathing of the subject. The detection of pulmonary congestion in the subject may be relatively passive for the subject. This may enhance the convenience and/or comfort of compliance to a detection regime by the subject. By detecting pulmonary congestion in the subject, potential episodes of heart failure may be identified and/or averted. The system and method may be configured to facilitate treatment of the subject to remediate detected pulmonary congestion and/or avert potential episodes of heart failure. For example, the system may provide enhanced access for a caregiver to detections of parameters related to pulmonary congestion in the subject.
