Brief History of the Nebulizer

The journey of nebulizer technology began in the mid-19th century when the need for better respiratory treatment became apparent. In 1858, French inventor Jean Sales-Girons created the first powered nebulizer, called the pulverisateur, which used a hand-pump mechanism to atomize liquid medication into a fine mist. This was followed by the steam-driven spray inhaler invented in Germany in 1864, which used the Venturi principle to convert liquid medication into vapor.

The 20th century brought significant advances. The first electric compressor nebulizer, the Pneumostat, was introduced in the 1930s, though its high cost limited accessibility. The 1950s saw a breakthrough with the Wright nebulizer, which used precision-molded plastic to create much finer aerosol particles suitable for deep lung delivery. Ultrasonic nebulizers arrived in the 1960s using high-frequency vibrations to create mist without compressed air. The most recent innovation came around 2005 with vibrating mesh technology, combining the benefits of previous designs into portable, efficient, and quiet devices that are widely used today in homes and hospitals worldwide.

What is a Nebulizer and Where is it Used?

A nebulizer is a medical device that converts liquid medication into a fine mist or aerosol that can be easily inhaled deep into the lungs. Unlike inhalers that require coordination and proper technique, nebulizers deliver medication through gentle breathing, making them particularly suitable for young children, infants, elderly patients, and anyone who has difficulty using traditional inhalers.

Common Uses

• Asthma: Delivering bronchodilators like albuterol or salbutamol to open airways during attacks or for maintenance therapy
• Chronic Obstructive Pulmonary Disease (COPD): Administering medications to ease breathing difficulties
• Cystic Fibrosis: Delivering antibiotics, mucolytics like DNase, and other specialized medications
• Bronchiolitis: Treating viral respiratory infections in infants and young children
• Pneumonia: Delivering certain antibiotic treatments directly to the lungs
• Allergic Reactions: Administering corticosteroids and bronchodilators during severe allergic responses

Where Nebulizers are Used

• Home settings for daily medication or emergency treatment
• Hospitals and emergency departments for acute respiratory distress
• Pediatric clinics and healthcare facilities
• Schools and daycare centers for children with chronic conditions
• Rehabilitation centers and nursing homes

Different Types of Nebulizers

Understanding the different types helps you choose the right nebulizer for your needs. Each type has unique features, advantages, and limitations.

How to Use a Nebulizer: Step-by-Step Guide

Proper use of a nebulizer ensures your child receives the full dose of medication effectively. Follow these steps carefully each time you give a treatment.

1. Wash Your Hands: Clean your hands thoroughly with soap and water for at least 20 seconds. This prevents contamination of the medication and equipment.
2. Prepare the Equipment: Place the nebulizer on a flat, stable surface. Connect the tubing to the compressor unit. Check that all parts are clean and dry from the previous treatment.
3. Add the Medication: Open the medicine cup by twisting or pulling it apart. Pour the prescribed amount of medication into the cup. If using a pre-measured dose, squeeze the entire contents into the cup. Do not dilute unless instructed by your doctor. Close the medicine cup securely.
4. Attach the Mouthpiece or Mask: For children who can cooperate, attach the mouthpiece to the medicine cup. For younger children or infants, use a face mask that covers both nose and mouth. Ensure the mask fits snugly but comfortably against the face without gaps.
5. Position Your Child Comfortably: Have your child sit upright in a chair or on your lap. Good posture helps medication reach deep into the lungs. Never give a nebulizer treatment while the child is lying flat.
6. Turn On the Nebulizer: Switch on the compressor. You should immediately see a fine mist coming from the mouthpiece or mask. If no mist appears, check all connections and try again.
7. Begin Treatment: If using a mouthpiece, have your child place it between their teeth and close their lips around it forming a seal. Encourage them to breathe normally through their mouth. If using a mask, hold it firmly but gently against the face covering both nose and mouth. Keep the medicine cup upright throughout treatment.
8. Breathe Normally: Instruct your child to breathe slowly and deeply when possible, but normal breathing is also effective. There is no need to take rapid or forced breaths. The entire treatment typically takes 10 to 15 minutes.
9. Continue Until Complete: The treatment is finished when the mist stops and only a small amount of liquid remains in the cup. You may hear a sputtering sound near the end. Gently tap the sides of the medicine cup to ensure all medication is nebulized.
10. Clean Up Immediately: Turn off the nebulizer. Disconnect the parts. Rinse the mouth with water and wipe the face if using a mask. Clean all parts immediately after use following the cleaning instructions below.

Precautions and Safety Measures

Following safety guidelines ensures effective treatment and prevents complications.

Important Safety Points

• Use only prescribed medications: Never use medication prescribed for another person or change the dose without consulting your doctor
• Check medication expiry dates: Expired medications may be ineffective or harmful
• Sterile solutions only: Use only sterile saline or water if dilution is needed. Never use tap water
• Watch for side effects: Common side effects include rapid heartbeat, trembling, nervousness, or headache. Contact your doctor if these persist or worsen
• Emergency symptoms: Seek immediate medical help if breathing worsens, lips turn blue, extreme drowsiness occurs, or the child cannot speak in full sentences
• Electrical safety: Keep the compressor away from water. Do not use in bathrooms or near sinks. Ensure the power cord is not damaged
• Proper positioning: Never give nebulizer treatment while child is lying flat as this reduces effectiveness and increases choking risk
• Monitor treatment: Always supervise children during nebulizer use. Never leave a child alone with a running nebulizer
• Storage: Store medications according to package instructions. Some need refrigeration while others should be kept at room temperature

Potential Complications to Watch For

• Oral thrush: Can occur when using steroid medications. Rinse mouth thoroughly after each treatment
• Paradoxical bronchospasm: Rare worsening of breathing immediately after treatment. Stop use and contact doctor immediately
• Infections: Can develop from contaminated equipment. Always clean and disinfect properly
• Medication interactions: Inform your doctor about all medications your child takes

Cleaning and Maintenance: Keeping Your Nebulizer Safe

Proper cleaning is crucial to prevent lung infections and ensure the nebulizer works effectively. Cleaning guidelines are based on recommendations from the Centers for Disease Control and Prevention and the Cystic Fibrosis Foundation.

After Every Treatment

1. Disassemble Immediately: Take apart the medicine cup, mouthpiece or mask, and any connecting pieces. Do not wash the tubing or compressor.
2. Rinse with Water: Rinse all parts under warm running water to remove medication residue. Shake off excess water.
3. Wash with Soap: Wash all parts with warm water and mild dish detergent. Avoid antibacterial soap or harsh cleaners. Scrub gently to remove any residue.
4. Rinse Thoroughly: Rinse all parts completely under warm running water to remove all soap. Any soap left behind can irritate the airways.
