Apparatus and Method for Measuring Nitric Oxide in Exhaled Breath
First Claim
1. A sensing apparatus to measure nitric oxide (NO) in exhaled breath, the sensing apparatus comprising:
- an inlet to receive the exhaled breath;
a pretreatment element to receive the exhaled breath from the inlet and to condition a chemical characteristic of the exhaled breath; and
a sensing electrode coupled to a chamber within the sensing apparatus, the chamber to receive the pretreated exhaled breath from the pretreatment element, the sensing electrode to detect a component of nitrogen oxide (NOX) in the exhaled breath.

Abstract
A sensing apparatus to measure nitric oxide (NO) in exhaled breath is disclosed. An embodiment of the sensing apparatus includes an inlet, a pretreatment element, and a sensing electrode. The inlet is configured to receive the exhaled breath. The pretreatment element is configured to receive the exhaled breath from the inlet and to condition a chemical characteristic of the exhaled breath. The sensing electrode is coupled to a chamber within the sensing apparatus. The chamber is configured to receive the pretreated exhaled breath from the pretreatment element. The sensing electrode is configured to detect a component of nitrogen oxide (NOX) in the exhaled breath.
