An ultrasonic nebulizer is a medical device that uses ultrasonic waves to convert liquid medication into a fine mist or aerosol that can be inhaled into the respiratory system. This mist can then deliver medication directly to the lungs, providing targeted treatment for respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and cystic fibrosis. Ultrasonic nebulizers are known for their efficiency and effectiveness in delivering medication quickly and effectively. They are also generally quiet and easy to use, making them a popular choice for both children and adults.
