Abstract:
1. An NO sensing system for measuring NO in a breath sample, the system comprising: an inlet configured to receive the breath sample as it is exhaled by a subject; a humidifier fluidly communicating with the inlet and configured to humidify the breath sample as it transmits the breath sample through the humidifier to a humidifier outlet, such that the breath sample exits the humidifier outlet as a humidified sample having a humidity above a predetermined level; and a sensing element comprising a plurality of sensors electrically coupled together, each of the plurality of sensors configured to generate a potential difference in response to presence of NO in the humidified sample; wherein the plurality of sensors comprises an effective number of sensors coupled together such that a combined potential difference of the plurality of sensors can indicate a level of NO less than about 100 ppb in the breath sample.
