Abstract
This document discusses, among other things, using a pressure sensor to detect body sound information of a patient, such as cardiac murmurs, respiratory sounds, etc.
Claims20
A system, comprising:
- a pressure sensor configured to receive physiologic information from a patient;
- and
- a control circuit, coupled to the pressure sensor, configured to receive information from the pressure sensor, and to provide a control signal to the pressure sensor, wherein the control circuit includes:
- a low-frequency data processing circuit configured to detect pressure information from the patient using the physiologic information received by the pressure sensor when the control signal is in a first state;
- and
- a high-frequency data processing circuit configured to detect body sound information from the patient using the physiologic information received by the pressure sensor when the control signal is in a second state.

A method, comprising:
- providing a control signal to a pressure sensor using a control circuit;
- receiving physiologic information from a patient using the pressure sensor;
- detecting pressure information from the patient using the physiologic information received by the pressure sensor when the control signal is in a first state using a low-frequency data processing circuit;
- and
- detecting body sound information from the patient using the physiologic information received by the pressure sensor when the control signal is in a second state using a high-frequency data processing circuit.
