Chronic obstructive pulmonary disease is the fourth leading cause of death in Vietnam. Early diagnosis and timely intervention will greatly help in the treatment of the disease.

Pulmonary function testing, also known as spirometry, is a test used to screen, diagnose, and monitor respiratory diseases such as asthma, chronic obstructive pulmonary disease, and restrictive lung disease.

Pulmonary function tests are a way to measure how well you breathe in and out of your lungs, and how much oxygen is getting into your body. The most common respiratory function tests are spirometry, diffusion studies, and plethysmography. So what do the respiratory function tests mean?

Treatment of respiratory diseases requires a comprehensive process including treatment of the cause, treatment of symptoms and rehabilitation. In which, the rehabilitation process plays an extremely important role.

To accurately assess the condition of the lungs or monitor the response to treatment in patients, doctors often use respiratory function measurements. This is one of the methods that uses a machine to measure the flow of air when the patient inhales and exhales to calculate many important lung function indicators.

Measuring pulmonary ventilation function by spirometry is a non-invasive method of examining pulmonary function. This technique aims to evaluate the respiratory function of the lungs, thereby detecting some disorders or diseases in the lungs, assessing the severity of the disease and the response to treatment with drugs.

Respiratory index is a typical parameter of the respiratory function test to see if the airway is good or not. In addition, it is also used as a basis for diagnosing diseases such as: chronic obstructive pulmonary disease, bronchial asthma, pulmonary fibrosis...

Forced vital capacity (FVC) is one of the indicators performed to examine respiratory function. So what is forced vital capacity, and how is forced vital capacity measured?

Oscillometry is a new method of exploring the mechanical characteristics of the respiratory system, widely used with many different subjects and cases where spirometry is contraindicated to determine some respiratory diseases. Pulse oscillometry has many advantages such as being quick and simple, requiring minimal cooperation from the patient.

Respiratory function testing, also known as ventilation function testing or spirometry, is a test used to screen, diagnose, and monitor respiratory diseases such as asthma, chronic obstructive pulmonary disease, and restrictive lung disease.
