How to measure lung capacity?

Lungs are the most important respiratory organs in our body. Among them, vital capacity is the simplest way to check the lungs. It can well detect the development of the lungs. Especially people with low vital capacity are particularly prone to hypoxia and other phenomena, which is particularly detrimental to health. However, many people do not particularly understand the method of vital capacity detection and always think it is a very complicated matter. Let's learn about how to measure vital capacity.

How to measure lung capacity?

Today I will teach you how to make a simple spirometer and measure your lung capacity easily. Just slightly change the spirometer above and the measurement will become very simple. Let's modify it together:

1. Solve the problem that one hand cannot hold a large bottle. Use a plastic bottle with a handle (about 1800ml cooking oil bottle or wine bottle) to make a simple spirometer. When measuring, hold the handle of the measuring device with one hand and hold it steady; as shown in Figure 3

2. When fixing the ventilation tube on the plastic bottle to make a spirometer, first fix the ventilation tube on the plastic bottle, and don't be careful that the other end of the tube falls out during measurement. Find a rubber transparent hose and drill a small hole at the bottleneck of the plastic bottle. The size of the small hole should be slightly smaller than the rubber tube. After the small hole is drilled, squeeze the rubber hose into it. In this way, depending on the elastic force of the rubber tube, the rubber hose will automatically lock in the small hole and be firmly fixed on the measuring bottle (as shown in Figure 3).

3. Make the spirometry scale as accurately as possible so that the measured data will be accurate. Find a drinking cup with a ruler, and pour 100ml of water into the plastic bottle at a time. Pour 100ml of water into the plastic bottle and make a mark on the horizontal surface of the bottle wall with an oil-based colored pen. After completing all this, lengthen the marks at 500ml, 1000ml and 1500ml to make it easier to read the data accurately when measuring.

After this modification, the spirometry device no longer needs a catheter when measuring. It can be held more steadily and the step of inserting a catheter is omitted. You just need to blow air, which is quick and efficient. You can do all these independently, right?

Experts remind: Cardiopulmonary function is the ability of the human heart to pump blood and the lungs to inhale oxygen, and the abilities of both directly affect the activities of organs and muscles throughout the body, so it is very important. If your lung capacity is measured to be too small, it may affect your cardiopulmonary function, so you should exercise more. Jogging, swimming, chest expansion exercises, stretching exercises, abdominal breathing, deep breathing, playing the flute, playing the harmonica, etc. can all enhance your cardiopulmonary function.

The above is an introduction to how to measure vital capacity... After understanding it, we know that vital capacity testing is very simple and quick, and can accurately grasp the condition of our lungs. In addition, low vital capacity does not mean that there is a lung disease. As long as you run more or do deep breathing exercises, you can improve your lung capacity. In addition, we should try not to smoke a lot, as this can easily cause certain damage to the lungs.
