Abstract
A system for correcting the concentration of NO.sub.2 detected by an electrochemical monitor in an apparatus for administering NO to a patient for therapeutic purposes. The system determines the effective monitoring time between the point in time that the sample of NO containing gas is removed by a sample conduit from the supply conduit to the patient and the point in time that the NO.sub.2 monitor actually analyzes the sample and determines the additional amount of NO.sub.2 that has been formed in the time-related reaction between NO and O.sub.2 in the sample conduit. Using that additional NO.sub.2 calculated value, the reading of the NO.sub.2 monitor is corrected to subtract that additional calculated NO.sub.2 from the monitor read value to produce a corrected, more accurate reading to the user.
