Chest X-rays are not very valuable in the definitive diagnosis of COPD but play an important role in the direction of the disease. Abnormal test results combined with history and other tests will help make an accurate diagnosis, excluding respiratory diseases with similar symptoms.

Pulmonary ventilation is a method of overcoming air stagnation in the lungs and increasing respiratory movement of the chest used for people with chronic obstructive pulmonary disease to treat and quickly relieve congestion.

Pulmonary ventilation testing is indicated to assess the types and levels of pulmonary ventilation disorders; assess symptoms of dyspnea, cough; early detection of respiratory dysfunction such as interstitial lung disease, chronic obstructive pulmonary disease. In addition, pulmonary ventilation testing also assesses the level of reduced lung function for occupational diseases, chronic lung diseases; assess treatment effectiveness, assess the patient's lung function before surgery...

To assess the condition of lung ventilation in some patients with chronic obstructive pulmonary disease, bronchial asthma, obstructive bronchitis, ... Doctors often prescribe magnetic resonance imaging of the lungs. The procedure of performing magnetic resonance imaging of the lungs shows images of the chest, from which it is possible to assess the function as well as lung diseases.

Plethysmography is a method of measuring total lung capacity using a plethysmography chamber. Plethysmography is used to confirm restrictive ventilation disorders and to differentiate between restrictive and restrictive ventilation disorders.

Although extensive research has been conducted to better understand the pathogenesis of Acute Respiratory Distress Syndrome (ARDS), there is no treatment or medication that can reduce the mortality rate of ARDS.
