Do you know the detection method of lung function detector?

Pulmonary function test items can objectively determine whether the airflow is blocked. For this purpose, pulmonary function test instrument is commonly used for examination, which is very helpful for the diagnosis of copd and the understanding of the disease.

So how does the reusable function function operate through the line detection type? Let's start with a few key words:

1.FEV1(forced expiratory volume at the beginning of one second) means that the patient breathes out as hard as possible after hard deep inhalation to determine the volume of exhaled gas within the first second.

2.FVC(forced vital capacity), also known as forced expiratory capacity, refers to the volume of larger gases that can be exhaled by inhaling to the total volume of the lungs and then exhaling with greater force and faster speed to the residual volume.

3.VC(vital capacity), also called slow vital capacity (SVC), refers to the slow, non-forceful exhalation of a large volume after hard deep inhalation to the total lung volume.

　　A series of methods were used to detect the lung gas exchange function. Including lung volume measurement, lung ventilation function measurement, lung ventilation, blood flow distribution and ventilation/blood flow ratio measurement, gas dispersion, lung compliance, airway resistance, small airway function measurement and exercise test, arterial blood gas analysis, etc. Clinical routine examination items are lung volume measurement, lung ventilation function measurement and arterial blood gas analysis. A lung function detector is a device that performs a lung function test and is used to assess the speed and efficiency of the lung's exhalation.
