1. A system for measuring nitric oxide or one of its metabolic products, the system comprising:
- a reaction chamber;
a fluid flow path extending between an end adapted for receiving a sample of bodily fluid and the reaction chamber;
a filter in the flow path;
a pump for advancing the sample through the filter to produce a filtrate and advancing the filtrate into the reaction chamber; and
a sensor in communication with the reaction chamber for determining a concentration of nitric oxide or one of its metabolic products.

Abstract
A system is disclosed that extracts bodily fluid to a reaction chamber for monitoring a substance or property of the patient fluid. In one embodiment, a pump is used to advance the sample of bodily fluid through a filter to produce a filtrate. Another pump advances filtrate into the reaction chamber, while another pump advances reactant into the reaction chamber. A sensor in communication with the reaction chamber determines a concentration of nitric oxide or one of its metabolic products. Methods are also disclosed.
