3. The aerosol flow rate can be regulated by adjusting the flow rate controller as shown at
right. The recommended practice, especially for children, is to set to the "Minimum" po-
sition in order to promote the deposit of the nebulized aerosol directly in the airways.
4. Once the mist generated is no longer constant, it means the medication in the medica-
tion cup is running out; but continue the therapy until there is no aerosol at all.
Note: At the end of inhalation therapy, a small amount of the medication (about 0.4 ml) will
remain in the medication cup; this is normal. This portion of the medication, called the "residual
volume", cannot be nebulized.
5. Disconnect the plug from the device's power socket.
Automatic Valve System
The device's mouthpiece has a two-valve system to ensure maximum efficiency of the inha-
lation and to minimize medication waste. In practice, the mouthpiece expiration valve will
open during expiration, allowing the patient's exhaled air to pass to atmosphere, avoiding
contamination of the device. During inspiration, the valve will close, maximizing the inhala-
tion amount.
