Nebulizer Therapy Nursing Procedure and Considerations

Nebulizer therapy gets medication straight into the lungs as a fine mist, which is why it works fast for asthma, COPD, and acute bronchospasm. Your job is accurate administration, watching for adverse reactions, coaching the patient, and keeping the equipment clean.

What is Nebulizer Therapy?

Nebulization delivers medication into the lungs in aerosol form. The nebulizer turns liquid medication into a fine mist the patient inhales deep into the respiratory tract. It is common for conditions that respond to bronchodilators, corticosteroids, or mucolytics.

Indications

• Asthma. Relieves bronchoconstriction and reduces inflammation.
• COPD. Improves airflow and reduces airway resistance.
• Cystic fibrosis. Loosens thick mucus secretions.
• Respiratory infection. Eases breathing and clears mucus.
• Bronchiectasis. Mobilizes secretions.
• Acute respiratory distress. Rapid symptom relief.

Contraindications

• Allergy to the medication. Avoid with known hypersensitivity.
• Unstable cardiovascular conditions. Some nebulized drugs affect heart rate or blood pressure.
• Severe anxiety or cognitive impairment. The patient may not tolerate the mask or mouthpiece.
• Pulmonary edema or severe fluid overload. Nebulization can worsen symptoms.

Equipment

• Nebulizer machine generates the aerosol.
• Nebulizer cup holds the medication and attaches to the mouthpiece or mask.
• Tubing connects the cup to the machine.
• Mouthpiece or mask (masks for children or patients who cannot use a mouthpiece).
• Medication in liquid form.
• Sterile saline to dilute if prescribed.
• Tissues and water for comfort after treatment.

Types of Nebulizers

• Jet nebulizer. Compressed air or oxygen draws liquid medication into a fine aerosol mist.
• Ultrasonic nebulizer. High-frequency sound waves vibrate a piezoelectric crystal to make the mist.
• Mesh nebulizer. Pushes liquid through a vibrating perforated plate.
• Vibrating mesh nebulizer (VMN). A mesh type using rapid mesh vibration to aerosolize the drug.

Medications for Nebulization

Medication	Classification	Dosage	Nursing Precautions
Albuterol (Salbutamol)	Bronchodilator (Short-acting beta-agonist)	2.5 mg every 4-6 hours (diluted in 2.5 mL saline, as prescribed)	- Monitor respiratory status and heart rate before and after administration. - Observe for signs of tachycardia, tremors, or nervousness. - Use with caution in patients with cardiovascular conditions.
Budesonide	Corticosteroid	0.25-1 mg twice daily	- Rinse the mouth after use to prevent oral thrush. - Do not use for acute asthma attacks; it is for maintenance therapy. - Monitor for signs of adrenal suppression with long-term use.
Ipratropium Bromide	Anticholinergic Bronchodilator	0.5 mg every 6-8 hours	- Monitor for dry mouth, dizziness, or blurred vision . - Avoid contact with eyes to prevent blurred vision or irritation. - Use with caution in patients with glaucoma or urinary retention .
Acetylcysteine (Mucomyst)	Mucolytic Agent	3-5 mL of 20% solution or 6-10 mL of 10% solution, 3-4 times daily	- Monitor for bronchospasm ; may require bronchodilator pre-treatment. - Monitor for respiratory distress during treatment. - Warn about an unpleasant odor (rotten eggs) and possible throat irritation.
Cromolyn Sodium	Mast Cell Stabilizer	20 mg via nebulization 4 times daily	- Cromolyn sodium is preventive, not used for acute asthma attacks. - Watch for bronchospasm after nebulization. - Avoid abrupt discontinuation as stopping suddenly may worsen symptoms.
Tobramycin	Antibiotic (Aminoglycoside)	300 mg twice daily	- Monitor renal function and hearing for signs of ototoxicity. - Instruct patients not to mix with other medications in the nebulizer. - Watch for voice changes or hoarseness during therapy.
Epinephrine	Sympathomimetic (Adrenergic Agonist)	0.5 mL of 1% solution diluted in 2.5 mL saline	- Monitor cardiovascular status closely for tachycardia and hypertension . - Reserve for acute settings like severe asthma or anaphylaxis . - Observe for signs of nervousness or palpitations.
Hypertonic Saline	Osmotic Agent	3-5 mL of 3-7% solution 2-4 times daily	- Pre-treat with a bronchodilator if indicated to prevent bronchospasm . - Monitor for throat irritation and coughing . - Ensure patient comfort during administration.

Assisting with Nebulizer Therapy

Pre-Nebulizer Assessment

1. Measure and document heart rate (HR), respiratory rate (RR), oxygen saturation (O₂), and lung sounds for a baseline.
2. If the HR is above 120 bpm, hold the treatment, notify the physician, wait 10-15 minutes, and reassess. A high HR can signal stress or a contraindication to bronchodilators.

Nebulization

1. Confirm medication, dose, and frequency against the physician's order.
2. Explain the purpose and steps to the patient and answer questions.
3. Wash your hands and assemble the machine, tubing, and medication cup.
4. Position the patient upright or in semi-Fowler's for full lung expansion.
5. Pour the prescribed medication into the cup, attach the mouthpiece or mask, and set the flowmeter to the recommended rate (usually 6-8 L/min) for adequate misting.
6. Have the patient seal the lips on the mouthpiece, chin up (or chin up with a mask), keeping the nebulizer upright.
7. Have them breathe normally until the nebulizer sputters, then tap it to release any remaining medication. Treatment usually runs 5-10 minutes.
8. When the cup is empty or mist stops, turn off the machine and disconnect the equipment.
9. Encourage coughing and expectoration, and give oral care if corticosteroids were used.
10. Return the bed to a comfortable position.

Post-Nebulization Assessment

1. Reassess vital signs or respiratory status as directed. Rinse the cup with 3 ml of sterile water, place it in a labeled plastic bag, and hang it from the oxygen regulator.
2. Document the administration and any teaching in the electronic health record (EHR).

Side Effects

• Tachycardia. Beta-agonist bronchodilators can raise the heart rate and cause palpitations.
• Shakiness or tremors. Common with beta-agonists, temporary but distressing.
• Dry mouth and throat irritation from continuous nebulization.
• Oral thrush with inhaled corticosteroids; rinse the mouth after each use.
• Headache or dizziness, especially if the patient hyperventilates.

Nursing Considerations

1. Check RR, oxygen saturation, and HR before and after.
2. Double-check medication type, dose, and expiration date.
3. Assess lung sounds, breathing pattern, and cough before and after.
4. Watch for tremors, tachycardia, or respiratory distress.
5. Coach calm, slow breathing to prevent hyperventilation.
6. Clean components after each use and store them dry.
7. Teach correct use and cleaning, especially for home use.
8. Teach precautions: rinse the mouth after corticosteroids, and recognize bronchodilator side effects.
