Chronic obstructive pulmonary disease (COPD) is the leading cause of disability and death in the world. However, diagnosis of COPD and early treatment of the disease can reduce the severe course of the disease, reduce the risk of death and reduce the burden on the socio-economic.

1. Learn about chronic obstructive pulmonary disease

Chronic Obstructive Pulmonary Disease (COPD) is a disease characterized by worsening progressive airway obstruction. The disease is associated with an abnormal inflammatory reaction of the airways and lungulmonary toy by toxic gases. Exacerbation of chronic obstructive pulmonary disease and like-for-like diseases can increase severe levels in patients. This is the cause of disability, death in humans, significantly increasing the socio-economic burden.

Although it is a dangerous disease and has many complications, it is completely preventable and treatable. Accordingly, early detection and treatment of COPD can reduce the severe course of the disease, reduce the risk of accidents and deaths in patients. Depending on the level of assessment of COPD with FEV1 to make accurate conclusions and have appropriate treatment options.

Assess COPD with FEV1 to determine the severeness of the disease

The assessment of COPD is aimed at determining the serious weight of the disease, the effects on the patient's health status, future risks (exacerbation, hospitalization, death) to take appropriate preventive and treatment measures. Aspects assessed include symptoms, degree of airway obstruction, risk of exacerbating of the disease, and assessment of associated conditions.

2.1 What does FEV1 mean?

Respiration is a method of measuring respiratory function that helps to assess the functioning of the lungs through inhalation and exhalation, the diagnosis of lung diseases, most commonly chronic obstructive pulmonary disease. At the same time, respiratory signatures are also used to monitor the severe – mild level of lung disease and monitor the effectiveness of treatment of the disease.

The respiratory machine measures the volume and speed of the air flow the patient inhales – exhales. The parameters noted by the device include:

  • FEV1 (short for Forced expiratory volume in one second). If the lungs and airways are normal, a person can blow out most of the air from the lungs within 1 second;
  • Vitality (FVC): Maximum volume of gas that can be blown out;
  • FEV1/FVC index: The ratio between the two parameters above, helping to assess pulmonary obstruction.

2.2 Assess the severity of COPD with FEV1

Respiratory measurements can diagnose chronic obstructive pulmonary disease COPD. Specifically, if the respiratory tract is narrowed or blocked, it will cause the amount of exhaled air to decrease. Thus, the FEV1 index will decrease, the FEV1/FVC ratio is lower than normal. Accordingly, the FEV1 values that diagnose the severeness of COPD are:

  • Light stage: FEV1 index >80% of the theory, FEV1/FVC ratio <70%; có thể có hoặc không có triệu chứng mạn tính của bệnh như ho, khạc đờm,…;
  • Average period: 50%< chỉ số FEV1 <80% số lý thuyết, tỷ lệ FEV1/FVC <70%; có thể có hoặc không có triệu chứng mạn tính của bệnh như ho, khạc đờm, khó thở thường xuyên và tiến triển,…;
  • Heavy stage: 30%< chỉ số FEV1 <50% số lý thuyết, tỷ lệ FEV1/FVC <70%; có triệu chứng khó thở tăng và tái diễn bùng phát thành nhiều đợt, ảnh hưởng tới chất lượng cuộc sống của bệnh nhân,…;
  • Very heavy stage: FEV1 index <30% số lý thuyết, tỷ lệ FEV1/FVC <70% hoặc FEV1 <50% số lý thuyết nhưng kèm theo suy hô hấp hoặc có dấu hiệu suy tim phải.

It is possible to diagnose and assess the severeness of chronic obstructive pulmonary disease COPD by the value of FEV1. And when there are warning signs of disease, it is best for patients to go to the doctor for timely diagnosis and treatment, avoiding the risk of unpredictable complications.
