Chronic Obstructive Pulmonary Disease
(COPD)
Chronic Obstructive Pulmonary Disease (COPD) is characterized by a persistent airflow limitation in the respiratory airways, that is usually progressive and associated with chronic bronchial inflammation.
COPD
With Chronic Obstructive Pulmonary Disease(COPD), your patient may be suffered from shortage of breath, fatiqueness & dizziness when doing exercise or walking upstairs. It is accompanied by chronic coughing and sputum production. Tobacco smoke is the major factor of COPD (1-2-5), although indoor and outdoor air pollution and exposure to pollutants in the workplace are also risk factors.

The 5th leading cause of death in Hong Kong
COPD affects 210 million people around the world(3), and COPD is the fifth leading cause of death in Hong Kong, and further increases in its prevalence and mortality can be predicted in the coming decades.
Acute exacerbation episodes and prolonged worsening of symptoms mark the development of the disease and accelerate the decline of the respiratory function. COPD is sometimes diagnosed during one of these exacerbation episodes.
What is Oxygen Therapy?
By providing high concentration of oxygen through oxygen source (e.g. oxygen concentrator) to patient with cannula to improve their blood oxygen saturation (SpO2).
Benefits of Long-Term Oxygen Therapy (LTOT)
Clinical studies* have shown that Long-Term Oxygen Therapy can increases the oxygen in blood and provides a range of benefits that include1-2:
- Improve life expectancy
- Decrease hospitalization
- Improve quality of life
- Feeling less tired and less short of breath
- Increased ability to move about and to keep a social life
- Increased sleep and quality of life
- Improved heart function
