ABSTRACT

A quantitative evaluation of breathing systems currently in use with Rb-81 Kr-81m generators is presented. Four systems were evaluated: a reservoir unit, a disposable oxygen face mask unit, and two types of nasal oxygen cannula units. These systems were used on 30 patients. It was found that the reservoir breathing system (a) delivered approximately 10% more Kr-81m gas to the lungs, and (b) reduced the image collection time by a factor of two or more, compared with the other three systems.
