From the Guidelines
For severe acute exacerbation of chronic obstructive pulmonary disease (COPD) with significant tachycardia, combined nebulised treatment with 2.5–10 mg of a β agonist (such as salbutamol) and 250–500 µg ipratropium bromide should be considered. This approach is based on the guidelines from the British Thoracic Society Nebulizer Project Group 1. The use of a β agonist like salbutamol can help alleviate bronchospasm, while ipratropium bromide, an anticholinergic, can further reduce bronchoconstriction and mucus secretion without exacerbating tachycardia.
Key points to consider in the management of severe COPD exacerbations with significant tachycardia include:
- The severity of the exacerbation dictates the treatment approach, with nebulized treatments being preferred for more severe cases 1.
- Monitoring of arterial blood gas tensions is crucial in hospitalized patients to guide oxygen therapy and avoid worsening hypercapnia or acidosis 1.
- The choice of nebulizer driver (air vs. oxygen) depends on the patient's oxygenation status and risk of carbon dioxide retention 1.
- Patients should be closely monitored for improvement in respiratory symptoms and stabilization or reduction in heart rate during treatment.
In clinical practice, the combination of salbutamol and ipratropium bromide can be delivered via a nebulizer, typically in a dose of 2.5–5 mg salbutamol and 500 µg ipratropium bromide, repeated as necessary based on clinical response, usually every 4–6 hours for 24–48 hours or until the patient shows significant improvement 1. This approach prioritizes both the alleviation of bronchospasm and the minimization of adverse effects on heart rate, aligning with the goals of reducing morbidity, mortality, and improving quality of life in patients with severe COPD exacerbations.

CLINICAL PHARMACOLOGY The prime action of beta-adrenergic drugs is to stimulate adenyl cyclase, the enzyme which catalyzes the formation of cyclic-3',5'-adenosine monophosphate (cyclic AMP) from adenosine triphosphate (ATP). In controlled clinical trials, most patients exhibited an onset of improvement in pulmonary function within 5 minutes as determined by FEV1. FEV1 measurements also showed that the maximum average improvement in pulmonary function usually occurred at approximately 1 hour following inhalation of 2. 5 mg of albuterol by compressor-nebulizer and remained close to peak for 2 hours.
The nebulizer given for severe acute exacerbation of chronic obstructive pulmonary disease (COPD) with significant tachycardia is albuterol (INH) by compressor-nebulizer.
- The compressor-nebulizer is the device used to administer albuterol.
- Albuterol is the medication used to treat COPD exacerbations.
- The medication can produce cardiovascular effects, including increased heart rate, which is a consideration in patients with significant tachycardia 2.
From the Research
Nebulizer Options for Severe Acute Exacerbation of COPD
- For patients with severe acute exacerbation of COPD and significant tachycardia, the choice of nebulizer is crucial.
- Studies have shown that combination therapy with ipratropium bromide and a beta-agonist such as albuterol or salbutamol can be effective in treating acute severe asthma and COPD exacerbations 3, 4.
- A study published in 2012 found that a breath-activated nebulizer (BAN) produced greater bronchodilator responses than a continuous flow small-volume nebulizer (SVN) in patients with ECOPD, with improvements in inspiratory capacity and respiratory frequency 5.
- Another study published in 2011 found that nebulized albuterol and ipratropium did not cause significant tachycardia or tachyarrhythmias in critically ill adult patients, suggesting that this combination may be safe for use in patients with COPD and tachycardia 6.
- The specific nebulizer used may depend on the individual patient's needs and response to treatment, but options may include:
