How much do you know about the indexes of pulmonary function examination?

Introduction: For the human body, different organs have different functions, so these organs are very important. The lung is a very important organ for human breathing. Every expansion and contraction of the lung promotes people's breathing, and oxygen will be brought in during breathing, so it is very important for all cells in the body to absorb oxygen with blood circulation. But there are always some people who don't cherish it and will have lung disease. This situation needs to be examined, and some indicators will appear in the examination of lung function. What are the indexes of pulmonary function examination?

Some indexes of pulmonary function examination are still commonly used. The first is vital capacity, which is the total amount of gas that people can exhale after taking a deep breath. Adult vital capacity is 2400~3400 ml. Generally speaking, the more people exercise, the higher their lung capacity, and the less people exercise, the lower their lung capacity. The other is the maximum ventilation capacity of human lungs. The maximum ventilation volume of the lungs can be used to detect one of their overall lung indicators, and the other is the one-second forced expiratory volume, that is, the amount of gas forcibly exhaled in the first second after deep inhalation. At the same time, there is also a ventilation function check, which should be paid attention to during breathing. In addition, there are lung volume test and diffusion test. Lung volume test is to test how much air a patient's lungs can hold.

Pay attention to the health of the lungs. The health of the lungs is actually related to the gas inhaled by people. If the gas people breathe in is fresh, then the lungs are healthier. However, if the gas inhaled by people because of work contains dust or smokes all the year round, then the lungs are easily affected. Therefore, in daily life, to avoid the harm of bad air to the body, protecting lung health is to protect life.
