Respiration signal measurement apparatus, systems, and methods
First Claim
1. An apparatus, comprising:
- a first port to sense a first respiration signal;
a second port to sense a second respiration signal; and
a measurement module capable of being communicatively coupled to the first and second ports to monitor the first and second respiration signals and to select a resulting signal as an indication of respiration.

Abstract
A cardiac rhythm management apparatus and system may include a first sensor to sense an atrial respiration signal, a second sensor to sense a ventricular respiration signal, and a measurement module capable of being communicatively coupled to the first and second sensors to monitor the atrial and ventricular respiration signals and to select a resulting signal as an indication of respiration. An article may cause a machine to implement a method which includes measuring a second signal responsive to a first signal, measuring a third signal responsive to a first signal, determining a respiration-to-cardiac ratio associated with each one of the second and third signals, and providing a resulting signal including a selected portion of a selected one of the second and third signals as an indication of respiration.

20. An article comprising a machine-accessible medium having associated data, wherein the data, when accessed, results in a machine performing:
-
measuring a second signal responsive to a first signal;
measuring a third signal responsive to a first signal;
determining a respiration-to-cardiac ratio associated with each one of the second and third signals; and
providing a resulting signal including a selected portion of a selected one of the second and third signals as an indication of respiration. - View Dependent Claims (21, 22, 23, 24)
