The most common types of inhalation devices include the following:
of controlled dose inhalerThe most common type of inhaler, the metered-dose inhaler, in most cases, uses a chemical propellant (chlorofluorocarbons, or CFCs) to remove the drug from the inhaler. There are now some MDIs that use CFCs to propel the medication. They are developing new types of delivery systems.
A metered-dose inhaler is held in front of the mouth or inserted into it as the drug is released in bursts. Consult your doctor for specific instructions on how to properly use a metered-dose inhaler.
NebulizerA nebulizer is a type of inhaler that sprays a fine, a liquid mixture of the drug. This is done through a mask, using oxygen or air under pressure, or an ultrasonic machine (often used by people who can not use a metered-dose inhaler, such as infants and young children and people with asthma severe).
The mouth is connected to a machine via plastic tubing to deliver medication to the patient. Consult your doctor for specific instructions on how to properly use a nebulizer.
Polvos the inhaler dry rotaryA dry powder inhaler unpressurised activated inhaler that may be used by children and adults, this type of inhaler does not use chlorofluorocarbon (Also called a CFC) to propel the medication out of the device. Consult your doctor for specific instructions on how to properly use an inhaler or dry powder rotary.
Making-dose inhalers more environmentally friendly:
Although many metered-dose inhalers still use chlorofluorocarbon (English CFC) to propel the medication out of the device, more and more inhalers are being replaced by non-CFC devices. The CFC, although safe for the person who inhaled, damage the ozone layer of the Earth - a layer that protects Earth from harmful sun rays. Other devices that previously used CFC, such as air conditioners and refrigerators, have already changed aa alternatives that do not use chlorofluorocarbons.
