Although there is currently no cure for COPD, treatments are available to help COPD patients with their day-to-day relief and long-term disease management.
The primary goals of treating COPD are to:
Given the progressive nature of COPD, treatment plans will vary depending on which stage of the disease your patients are facing.
Depending on the severity, patients experiencing acute exacerbations of COPD often suffer from increased airflow limitation, increased sputum production, airway inflammation, and respiratory insufficiency that can result in hypoxia, hypercapnia and respiratory acidosis.2
Recommended treatments for acute exacerbations may include:
While oxygen therapy is used to treat hypoxemic patients with impaired gas exchange or pulmonary failure, it does not adequately address carbon dioxide (CO2) retention in hypercapnic patients with ventilatory failure – but non-invasive ventilation can.3
The GOLD guidelines conclude that using non-invasive ventilation to manage acute exacerbations of COPD improves respiratory acidosis, decreases respiratory rate, reduces the severity of breathlessness, and lowers the rate of complications such as ventilator-associated pneumonia.1
Close to 20% of COPD patients who are hospitalised for an acute exacerbation are readmitted within 30 days.4 Another study found a readmission rate of 63% over a mean follow-up of 1.1 years.5
Using non-invasive ventilation to treat acute exacerbations in hospital has been shown to not only reduce readmission and lengths of stay, but also reduce the incidence of mortality and intubation.6 The prescribed use of non-invasive ventilation at home following COPD hospitalisation also suggests similar benefits.8
The long-term management of COPD seeks to optimise lung function, prevent exacerbations and slow disease progression. This often includes a self-management plan with multidisciplinary treatments tailored to suit individual patients.
Recommended treatments for better long-term outcomes may include:
With increasing burdens on our healthcare system, there has been interest shown for the use of non-invasive ventilation, not only when treating acute exacerbations, but also as a preventative therapy in the long-term management of COPD.2
A range of studies show encouraging findings when non-invasive ventilation is added to the treatment of COPD:
1. Improved survival for COPD patients
In a recent prospective, randomised controlled trial (Koehnlein et al. 2014), clinicians studied the use of home-based non-invasive ventilation compared to standard therapy for patients with stable hypercapnic COPD.
After a follow-up period of 12 months, the risk of mortality was 76% lower in the intervention group compared to the control group. Improvements were also reported for patient quality of life and exercise tolerance. 7

2. Clinical benefits for nocturnal non-invasive ventilation at home
A 2-year study (Duiverman et al. 2011) has demonstrated various clinical benefits for adding non-invasive ventilation to COPD treatment at home compared to pulmonary rehabilitation alone. The study reported improvements to the following outcomes, with benefits also increasing over time:
3. Home non-invasive ventilation reduces hospital readmissions
A retrospective study (Galli et al. 2014) assessed the outcomes for patients who were prescribed non-invasive ventilation at home compared to those who were not prescribed non-invasive ventilation.
Analysed data showed that patients who had been prescribed non-invasive ventilation at discharge were less likely to have been readmitted to hospital or readmitted with a stay in the intensive care unit.8

4. Home non-invasive ventilation reduces the probability of recurrent respiratory failure
A pilot trial (Cheung et al. 2010 ) observed that COPD patients with acute hypercapnic respiratory failure (AHRF) were less likely to experience a recurrent severe exacerbation when treated with non-invasive ventilation compared to treatment with CPAP. The prevalence of patients developing recurrent AHRF in the non-invasive ventilation group compared to the CPAP group was 38.5% to 60.2% at 1 year.11

With clinical evidence suggesting that non-invasive ventilation can improve quality of life and survival,7 and also help reduce the length of hospital stays and readmission rates,6 ResMed is working with respiratory physicians, healthcare systems and payors to increase awareness of non-invasive ventilation therapy, and has developed intelligent non-invasive ventilation solutions that are suitable for the treatment of COPD.
By choosing ResMed’s non-invasive solutions when treating COPD patients, you can provide an even more promising picture with every breath.
