Final answer:
MDI and SVN are two methods of delivering medication for respiratory conditions. MDI is a handheld device that delivers medication in a measured dose, while SVN is a machine that turns liquid medication into a fine mist. The choice between MDI and SVN depends on the specific condition and medication.
Step-by-step explanation:
MDI (Metered Dose Inhaler) and SVN (Small Volume Nebulizer) are two common methods of delivering medication for respiratory conditions. Both methods are used to treat asthma, chronic obstructive pulmonary disease (COPD), and other respiratory diseases.
MDI is a handheld device that delivers medication in a measured dose. It contains a canister filled with medication, a propellant, and a mouthpiece or mask. When the canister is pressed, it releases a fine mist of medication that the patient inhales. The medication is delivered directly to the lungs, providing quick relief of symptoms.
SVN is a machine that turns liquid medication into a fine mist that can be inhaled. The liquid medication is placed in a cup or container attached to the nebulizer, which then delivers the medication through a mouthpiece or mask. The patient breathes in the mist over some time, allowing the medication to reach the airways and provide relief.
The choice between MDI and SVN depends on several factors, including the type and severity of the respiratory condition, the specific medication being used, and the patient's preferences and abilities. Some medications are only available in MDI form, while others can be used in both MDI and SVN devices.
