Abstract: Organic nitrites can be produced from a compound which is a mono/polyhydric alcohol or an aldehyde- or ketone-derivate thereof after de-aeration of the same, using NO gas, and stored in an environment saturated with gaseous NO. Organic nitrites produced according to the invention exhibit less impurities and improved storage stability compared to conventionally produced nitrites. The organic nitrites of the invention can easily be formulated into pharmaceutical compositions and have utility for the treatment of various conditions.

Abstract: The invention relates to a method and to apparatus for ascertaining the current function or condition of a lung or the lungs of a living subject (1) chosen for a lung function evaluation, by measuring (3) the nitrogen monoxide content (NO) of the expiration air. The amount of nitrogen monoxide formed in the lung or the lungs during the expiration phase of one or more respiratory cycles and/or the time-distribution of the amount of nitrogen monoxide is compared (5) with the maximal nitrogen monoxide content and/or the time-distribution (6) of the nitrogen monoxide content of the exhalation air delivered by a complete, or unimpaired, lung function of a living subject, wherein a deviation disclosed by the comparison (9, 11) is normally interpreted as an impairment of the lung function.
