Nebulization involves administering drugs by inhalation through an electric or ultrasonic nebulizer that breaks liquid medications into fine mist. It is commonly used to deliver bronchodilators for asthma attacks. Other indications include administering antibiotics or analgesics to infants/children, aiding expectoration, and providing local lung analgesia. Proper preparation of the nebulizer, medications, patient, and environment is required. During treatment, the patient sits upright and breathes slowly and deeply through the mouthpiece for 15-20 minutes while monitored for complications like increased heart rate or wheezing. Outcomes such as loosened secretions are documented.
