Abstract: The disclosure describes a technique for monitoring patient utilization of inhaled Nitric Oxide as well as waste exhaust of Nitric Oxide in gases exhaled from patient lungs. By monitoring the real dose provided to a patient, actual compliance with therapeutic target doses may be monitored to improve patient safety and therapeutic benefit from inhaled Nitric Oxide. Simultaneously, unnecessary waste of inhaled Nitric Oxide may be avoided thereby increasing the cost effectiveness of Nitric Oxide therapy. The minimization of Nitric Oxide waste has the further benefit of reducing environmental Nitrogen Dioxide levels in e.g. a NICU environment thereby mitigating medical personnel's Nitrogen Dioxide exposure.
