Those who suffer from sleep apnea, Chronic Obstructive Pulmonary Disease (COPD), or another respiratory condition where a patient’s lungs cannot provide adequate oxygen from exclusively the outside air, may require or benefit from oxygen therapy.
Chronic Obstructive Pulmonary Disease (COPD ) is a persistent lung condition that gradually impedes airflow in the lungs resulting in shortness of breath. It presents multiple symptoms ranging from mild to severe and is usually accompanied by other conditions such as emphysema and bronchitis.
Chest congestion is a symptom of a respiratory infection and occurs when far too much mucus builds up in your lungs. When your body gets a respiratory infection, to protect itself it overproduces mucus hence creating congestion around your chest.
