1. A medical-device system, comprising:
a risk stratification circuit configured to:
receive physiological information including respiration information and heart sound information sensed from a patient;
generate distinct first, second, and third signal metrics using the received physiological information, the first signal metric generated using the received respiration information, the second or the third signal metric generated using the received heart sound information;
calculate a primary pulmonary risk score using the first signal metric, and calculate a secondary pulmonary risk score using the second and the third signal metrics, the primary pulmonary risk score and the secondary pulmonary risk score each taking a numerical value; and
calculate a composite pulmonary risk score using the primary and the secondary pulmonary risk scores; and
a physiological event detector circuit configured to detect a cardiorespiratory event of the patient based at least in part on the calculated composite pulmonary risk score.
