From the Guidelines
Deeper breathing during nebulization is a normal and expected response, as it helps maximize medication delivery to the airways and is often a result of the relaxation and opening of the airways caused by bronchodilator medications. When patients receive nebulized medications, they are typically instructed to take slow, deep breaths to maximize medication delivery to the airways. This breathing pattern helps the aerosolized medication particles penetrate deeper into the lungs, reaching the small airways where they can be most effective. The mist from the nebulizer naturally encourages deeper breathing as patients inhale the visible medication. Additionally, as bronchodilator medications (like albuterol or ipratropium bromide) begin to work, they relax and open the airways, which physically allows for deeper breathing, as noted in guidelines for nebulizer therapy 1. Some patients may also experience relief from symptoms like wheezing or chest tightness during treatment, further enabling deeper breaths. If a patient is unable to breathe deeply during nebulization, it might indicate severe airway obstruction or anxiety, which should be addressed by a healthcare provider. According to the European Respiratory Society guidelines on the use of nebulizers, treatment may be repeated within a few minutes if the patient has a suboptimal response to the first dose of nebulized treatment, and patients should be changed to hand-held inhalers as soon as their condition has stabilized 1.
Key points to consider:
- Deeper breathing during nebulization is a normal response to the treatment
- Bronchodilator medications help relax and open the airways, allowing for deeper breathing
- Patients should be instructed to take slow, deep breaths during nebulization to maximize medication delivery
- If a patient is unable to breathe deeply during nebulization, it may indicate a need for further medical evaluation, as suggested by guidelines for the management of chronic obstructive pulmonary disease 1.
From the FDA Drug Label
Breathe as calmly, deeply, and evenly as possible until no more mist is formed in the nebulizer chamber (about 5 to 15 minutes).
Breathing deeper during nebulization is a normal response as the patient is instructed to breathe deeply and evenly until the treatment is finished 2.
From the Research
Patient Response to Nebulization
- A patient breathing deeper during nebulization may be a normal response, as the treatment is designed to deliver medication directly to the respiratory tract, potentially leading to improved lung function and increased oxygen saturation 3.
- The effectiveness of nebulization depends on various factors, including the characteristics of the drug, the patient's inhalation technique, and the nebulization system employed 3.
- Studies have shown that nebulized therapy can be beneficial for patients with asthma and chronic obstructive pulmonary disease (COPD), with improvements in lung function and symptoms 4, 5.
Factors Influencing Nebulization Efficacy
- The particle size of the aerosolized medication is an important factor, with particles between 1 and 5 μm having the greatest probability of reaching the site of infection in the bronchial tree 3.
- The type of nebulization system used can also impact efficacy, with mesh nebulizers being the most effective and compact 3.
- Continuous nebulization therapy has been shown to be beneficial for patients with severe asthma, with factors such as particle size distribution, setup conditions, and aerosolization concentrations and rates influencing the delivery of prescribed drugs to the respiratory airways 6.
Clinical Implications
- The use of nebulized therapy, including combination treatments such as albuterol and ipratropium, has been shown to be effective in improving lung function and reducing symptoms in patients with asthma and COPD 4, 5.
- Healthcare providers should consider the individual patient's response to nebulization, including any changes in breathing patterns, when assessing the effectiveness of treatment 7.
