2. Aerosol devices

There are several types of devices that can generate aerosols:
- Nebulizers;
- Dry powder inhalation devices;
- Pressurized inhalation devices with measured doses.

Using each of these devices has advantages and disadvantages that must be understood in order to optimize health benefits. Aerosol therapy can be used including in mechanical ventilation as part of bronchodilator therapy, anti-inflammatory medication and sometimes for antibiotics or mucolytics instillation.

In order to be effective in different conditions, it is essential to know the principles and statements when aerosol therapy can be applied.

3. The aerosols and the human body

While a person breathes, aerosols penetrate the mouth, trachea, bronchi that branch into smaller respiratory passages called bronchioles which contain small air bags (alveoli).

Most often aerosol therapy uses bronchodilators that act to relax the airways so that they become more spacious resulting in an easier breathing. Most aerosol treatment lasts about 10 minutes and is recommended to be repeated 3-4 times a day.

4. Aerosol treatment – procedure

For aerosol therapy to be effective the specialists recommend the following steps:
- Is chosen an area that is comfortable, well lit and close to a power source;
- Connect the aerosol device to the power supply;
- Wash hands thoroughly before installing the parts of the aerosol device or before manipulating the medication;
- Pour medication into aerosol container special device;
- If the medication is packaged as a dose will measure the correct amount and dilute it with saline solution or water;
- The doctor will give you the exact quantities and specific instructions on medications mixing;
- Attach the lid to the container in which the drug solution was placed;
- Insert one end of the feeding tube into the aerosol device container and the other to its unit. Connect the other cable of the aerosol device unit to an outlet;
- The person who will benefit on this therapy will sit and will turn on the aerosol device. Should be able to see how the fines powders are released from the nebulizer mouthpiece. If this do not happen you must check again the connections and the amount of drug;
- Mouthpiece of the device will be held between the teeth, keeping the lips all around it and breathing normally through mouth, not through nose;
- Normal breathing rhythm is not accelerated for the drug to be distributed uniformly in the lungs;
