Abstract
A method of treating a subject suffering from, or susceptible to, a condition that can be ameliorated by inhalation of gaseous nitrite comprises the use of apparatus comprising an activating unit that includes a photosensitiser excitable by absorption of light to excite oxygen to a singlet state, and a light source arranged to illuminate the photosensitiser. Air is caused to flow through the activating unit while said photosensitiser is illuminated by the light source, and after passing through the activating unit, is directed to the respiratory tract of the subject.

Apparatus for producing singlet oxygen, the apparatus comprising
- a housing having an air inlet and an air outlet;
- a fan arranged within the housing to draw air from the air inlet to the air outlet;
- and
- an activating unit disposed in the path of the air from the air inlet to the air outlet, wherein the activating unit includes a photosensitiser excitable by absorption of light to excite oxygen to a singlet state, and a light source arranged to illuminate the photosensitiser;
- wherein the photosensitiser is coated on a planar substrate that is mounted on a carriage that, in use, extends through an opening in the housing such that the photosensitiser is positioned within the housing in juxtaposition with the light source, and wherein the carriage can be separated from the housing to permit replacement of the photosensitiser.
