[Technical aspects in the Pari provocation test I].
Several methods are in use for performing the unspecific provocation test. The Pari provocation test I instrument offers the possibility of employing the reservoir method that possesses several advantages. On testing individual parameters of this instrument we determined an aerosol performance of 0.086 +/- 0.002 ml/min for nozzle 1 and of 0.083 +/- 0.002 ml/min for nozzle 2. Reproducibility was very good, and so was the agreement between the two tested nozzles. The aerosol volume that was produced, was greater than stated if the setting was adjusted to 2.51 to 10.01; it was lower only if the instrument was set to 2.01. The reasons for this result are discussed. On the whole, the instrument can be considered as suitable for the performance of unspecific provocation tests, and can be recommended.
