innhalasjon

Innhalasjon is the process of breathing in a substance, typically a medication or vapor, into the lungs. This method of drug delivery is commonly used for respiratory conditions such as asthma, bronchitis, and emphysema. Inhaled medications are designed to act directly on the airways, providing rapid relief by reducing inflammation, relaxing constricted muscles, or thinning mucus.

There are several ways to administer inhaled medications. Nebulizers convert liquid medication into a fine mist that can be breathed in over several minutes. Metered-dose inhalers (MDIs) deliver a measured spray of medication when the canister is pressed. Dry powder inhalers (DPIs) release medication as a powder when the patient inhales through the device. The choice of inhaler often depends on the patient's age, ability to coordinate breathing with actuation, and the specific medication being used.

Besides therapeutic purposes, innhalasjon can also refer to the inhalation of harmful substances, such as smoke, pollutants, or volatile chemicals. This type of innhalasjon can lead to various respiratory problems, ranging from mild irritation to severe lung damage, depending on the substance and duration of exposure. Proper technique is crucial for effective and safe innhalasjon of medications to ensure the drug reaches the lungs properly and minimizes side effects. Healthcare professionals often provide instruction and training on the correct use of inhaler devices.
