Oa. Lindahl et al., AN ELECTROMECHANICAL BREATHING DEVICE FOR MINIMAL PARTICLE LOSS WHILEINHALING AEROSOLS, Journal of medical engineering & technology, 17(4), 1993, pp. 138-140
The design of an electromechanical breathing mask that minimizes parti
cle loss during inhalation of aerosols from a provocation box is descr
ibed. The device measures air flow by means of an anemometer. A provoc
ation example is depicted and the possibility of measuring the provoca
tion dose is discussed. The breathing device here described has been s
hown to be easy to use and to give reliable results.
