From the Guidelines

Pulmonary rehabilitation is a crucial component of the clinical management of patients with chronic respiratory diseases, aiming to reduce symptoms, optimize functional status, and improve quality of life. The lungs are vital respiratory organs that facilitate gas exchange between the bloodstream and the environment, and pulmonary rehabilitation programs are designed to address the functional and psychologic deficits associated with chronic respiratory diseases 1. These programs involve a multidisciplinary approach, including patient assessment, exercise training, education, nutritional intervention, and psychosocial support, to help patients become more physically active and independent in their daily activities 1.

The primary goal of pulmonary rehabilitation is to restore patients to the highest possible level of independent function, and it has been shown to be effective in reducing symptoms and disability from chronic lung diseases such as COPD, interstitial diseases, and cystic fibrosis 1. The interdisciplinary team of healthcare professionals involved in pulmonary rehabilitation may include physicians, nurses, respiratory therapists, and exercise specialists, among others, and the specific team makeup depends on the resources and expertise available 1.

Key components of pulmonary rehabilitation programs include:

  • Patient assessment to identify individual needs and goals
  • Exercise training to improve physical function and reduce symptoms
  • Education to promote self-management skills and self-efficacy
  • Nutritional intervention to optimize nutritional status
  • Psychosocial support to address emotional and psychological needs These components are designed to work together to improve overall health and well-being, and to reduce healthcare costs by stabilizing or reversing systemic manifestations of the disease 1.

In terms of specific recommendations, pulmonary rehabilitation should be considered an integral part of the clinical management of all patients with chronic respiratory diseases, and should be tailored to the individual needs and goals of each patient 1. By prioritizing pulmonary rehabilitation, healthcare providers can help improve the quality of life and reduce morbidity and mortality in patients with chronic respiratory diseases.

From the Research

Lung Health and Disease

  • Lung-related research focuses on the etiology and management of diseases, with growing interest in primary prevention and health promotion 2
  • Primary prevention includes population-based strategies to maximize lung health and mitigate age-related declines in lung function 2

Treatment and Management of Lung Diseases

  • Inhaled bronchodilators and corticosteroids are used to treat asthma-COPD overlap, with LABA associated with decreased risk of myocardial infarction and ICS/LABA reducing the risk of death or hospitalization 3
  • Breathing techniques, such as pursed lip and diaphragmatic breathing, can reduce breathlessness and improve health-related quality of life in people with serious respiratory illness, including COPD and asthma 4
  • Yoga breathing has also been shown to improve breathlessness and health-related quality of life in people with serious respiratory illness 4

Research Gaps and Future Directions

  • More research is needed on population-based strategies to promote lung health and prevent chronic lung diseases 2
  • Further studies are required to fully understand the effects of breathing techniques on breathlessness and health-related quality of life in people with serious respiratory illness 4
  • Additional research is needed to determine the safety and effectiveness of current pharmacotherapies for treating asthma-COPD overlap 3
