Acapella With Nebulization in Normal Subjects

"1. st Phase In this phase the jet nebulizer was connected to the branch end of the Acapella according to manufacturer's recommendations.~ The volunteer did the radio-aerosol inhalation to obtain images of the lung fields scintigraphy static during the period of 300 seconds using an array of at 256x256x16 incidence later, as that encompasses most incidence of lung volume.~2. nd Phase The experimental procedure of this phase was similar to the 1st stage, but what differed was it made an adjustment by placing a pipe T between the mouthpiece and the device Acapella so that the aerosol would be inhaled not pass through the device.~Stage 3 This stage was considered phase control since the aerosol inhalation was performed through the mouthpiece connected directly to the nebulizer as is routinely used in clinical practice as illustrated. The procedure of this phase followed the same protocol of previous phases."
