First Claim
1. A system comprising:
- a first implantable acoustic transducer, wherein the first implantable acoustic transducer is configured to receive transmitted acoustic energy from a thorax region of a subject;
a second implantable acoustic transducer, wherein the second implantable acoustic transducer is configured to transmit the acoustic energy to the thorax region;
a memory circuit; and
a processor communicatively coupled to the first acoustic transducer, the second acoustic transducer, and the memory circuit, wherein the processor includes;
a parameter module configured to measure a parameter of the received acoustic energy; and
a trending module configured to trend the measured parameter and to provide an indication of pulmonary edema status of the subject using the parameter trend.

Abstract
A system includes a first implantable acoustic transducer, a second implantable transducer a memory circuit, and a processor. The first implantable acoustic transducer is configured to receive transmitted acoustic energy from a thorax region of a subject and the second implantable acoustic transducer is configured to transmit the acoustic energy to the thorax region. The processor is communicatively coupled to the first acoustic transducer, the second acoustic transducer, and the memory circuit. The processor includes a parameter module configured to measure a parameter of the received acoustic energy, and a trending module configured to trend the measured parameter and to provide an indication of pulmonary edema status of the subject using the parameter trend.
