Perform inhalational provocation tests quickly and with reproducible results. GANSHORN's Provojet is a stand-alone, aerosol dosimeter that fulfills all necessary requirements no matter where the measurements are carried out. The threshold controlled, breath-synchronous application of the preset aerosol dose during the inspiration phase guarantees outstanding reproducible results. In many cases the setting of the atomising time allows the usage of only one single aerosol concentration – this saves time and money. Specific or non-specific bronchial challenge tests, single or multiple stage tests can be selected in a matter of seconds via the well arranged data entry pad. Up to six different standard provocation series (i.e. metacholin 0.33%) permanently stored with a maximum of 10 stages each. The dose per stage can alternatively be changed by either increasing the provocation fluid concentration and/or by changing the total atomising time.
