Inhalers
Inhalers
Inhalers (pronounced in-hay-lers) are medical devices used to deliver medication into the body via the lungs. They are primarily used in the treatment of asthma, chronic obstructive pulmonary disease (COPD), and other respiratory diseases.
Etymology
The term "inhaler" comes from the Latin word "inhalare", which means "to breathe in". It was first used in the medical context in the 19th century.
Types of Inhalers
There are two main types of inhalers: Metered Dose Inhalers (MDIs) and Dry Powder Inhalers (DPIs).
- Metered Dose Inhalers (MDIs) are the most common type of inhaler. They deliver a specific amount of medication in aerosol form with each puff.
- Dry Powder Inhalers (DPIs) deliver medication in a dry powder form. The patient must inhale more forcefully than with an MDI to get the medication into their lungs.
Usage
Inhalers are used by inserting the mouthpiece into the mouth, taking a deep breath, and pressing down on the canister to release the medication. The medication is then inhaled into the lungs. It is important to use inhalers correctly to ensure the right amount of medication reaches the lungs.
