From the Guidelines
Respiratory failure should be managed with non-invasive ventilation (NIV) as the first line of treatment, particularly in patients with chronic obstructive pulmonary disease (COPD) exacerbations, as it has been shown to improve outcomes and reduce the need for invasive mechanical ventilation 1.
Key Considerations
- Respiratory failure is a life-threatening condition that requires prompt intervention to prevent organ damage from inadequate oxygenation or acid-base disturbances.
- The goal of treatment is to minimize the negative impact of the current exacerbation and to prevent subsequent events, as outlined in the Global Strategy for the Diagnosis, Management, and Prevention of Chronic Obstructive Lung Disease report 1.
- NIV, such as bilevel NIV, may be considered in COPD patients with an acute exacerbation to prevent acute respiratory acidosis, prevent endotracheal intubation, or as an alternative to invasive ventilation 1.
Treatment Approach
- Supplemental oxygen therapy should be initiated at 2-4 L/min via nasal cannula, with potential escalation to NIV such as CPAP or BiPAP.
- Medications may include bronchodilators like albuterol, corticosteroids such as methylprednisolone, and antibiotics if infection is present.
- Addressing the underlying cause is crucial, whether it's treating pneumonia, managing COPD exacerbation, or resolving pulmonary edema.
Monitoring and Adjustments
- Regular monitoring of vital signs, oxygen saturation, and arterial blood gases is essential to guide therapy adjustments.
- The treatment approach should be individualized based on the patient's underlying condition, severity of respiratory failure, and response to initial therapy.
Prevention of Subsequent Events
- After an exacerbation, appropriate measures for exacerbation prevention should be initiated, including maintenance therapy with long-acting bronchodilators and other preventive strategies 1.

The ipratropium bromide inhalation solution drug label reports dyspnea (9.6%) as an adverse reaction, which is related to respiratory failure.
- Key points:
- Dyspnea is a symptom of respiratory failure.
- The drug label does not directly mention respiratory failure as an adverse reaction.
- However, dyspnea is a significant symptom that may indicate respiratory failure in some patients. 2
From the Research
Definition and Treatment of Respiratory Failure
- Respiratory failure is a life-threatening condition that can occur in patients with advanced chronic obstructive pulmonary disease (COPD) and other respiratory disorders 3.
- Treatment options for respiratory failure include supplemental oxygen, mechanical ventilation, and pharmacological therapy 3, 4.
Pharmacological Management of COPD
- Combination therapy with ipratropium and albuterol has been shown to be more effective than either agent alone in improving lung function and symptoms in patients with COPD 5, 6.
- Long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) combination therapy is recommended for patients with COPD and dyspnea or exercise intolerance 7.
- Triple therapy with inhaled corticosteroids (ICS)/LABA/LAMA may be considered for patients with COPD and a history of exacerbations 7.
Ventilator Strategies and Rescue Therapies
- Noninvasive ventilation is commonly used for patients with respiratory failure and has been shown to improve outcomes in acute exacerbations of COPD and congestive heart failure 4.
- Lung-protective tidal volumes and reduced FiO2 should be used for all patients receiving mechanical ventilation 4.
- Rescue therapies such as airway pressure release ventilation, continuous neuromuscular blockade, inhaled nitric oxide, and extracorporeal membrane oxygenation may be considered for patients with refractory hypoxemia 4.
