Abstract
Aerozol therapy is one of the most popular and conservative therapies for the upper respiratory infectious disease. A little attention, however, has been paid for its side-effects against medical staffs and indoor air pollution in the treatment room.
In this paper, these side-effects were discussed by measuring the concentration of the medical particles using in nebulizer in the indoor air and the blood of medical staffs. The results are as follows ; 1) the medicine concentration in blood of medical staffs were below detectable level. 2) In a closed room, the medicine concentration at the same level of nebulizer apparatus was ten times more than at 50 cm high from the nebulizer apparatus. These detected concentration decreased by 20% by using a ventilator. 3) In the treatment room, the medicine was detected 7 m apart from the nebulizer apparatus on the condition that the ventilator was not working.
In conclusion, the authors emphasize that the ventilator is necessary for nebulizer therapy, and plural and stronger ventilators are more effective for the indoor air pollution by nebulizer particles.
