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.
Claims9
A method of measuring a level of one or more metabolic products of nitric oxide in bodily fluid, comprising the steps of:
- directing a stream of bodily fluid through a filter to produce a filtrate;
- directing the filtrate into a reaction chamber;
- providing a reactant;
- directing the reactant into the reaction chamber to react with the filtrate to produce a reaction product;
- and
- measuring a concentration of one or more metabolic products of nitric oxide in the reaction product.
