A nebulizer is a medical device that converts liquid medication into a fine mist or aerosol that can be inhaled directly into the lungs through a mouthpiece or face mask. This allows the medicine to enter the respiratory system quickly and effectively, making it useful for treating lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), cystic fibrosis, and bronchiectasis
. There are three main types of nebulizers:
- Jet nebulizers : Use compressed air to turn liquid medicine into a mist. They are commonly used in hospitals and are relatively low cost but can be noisy and less portable
- Ultrasonic nebulizers : Use high-frequency vibrations to create the mist. They tend to be quieter but more expensive, and produce slightly larger droplets
- Mesh nebulizers : Pass medicine through a fine mesh to generate a mist. These are often more compact and portable
Nebulizers can be tabletop devices plugged into electrical outlets or portable battery-operated units. They are typically prescribed by healthcare providers and require proper cleaning and maintenance to ensure effectiveness and reduce infection risk
. While nebulizers are effective for delivering medication, for many asthma patients, inhalers with spacers are now preferred because they are easier to use, faster, cheaper, and more portable. However, nebulizers remain important for patients who have difficulty using inhalers or during severe respiratory episodes
