What should a girl's lung capacity be?

Nowadays, many people lack exercise, which leads to many patients needing to take appropriate measures in time to ensure their health. Especially some women have problems with their lung capacity. In this case, they need to take timely treatment and examination to ensure their health. So what should be the lung capacity of girls? Let me introduce this issue to you below.

The lung capacity of an adult male is about 3500 ml, and that of an adult female is about 2500 ml. Physiological research shows that the human body's organs, systems, tissues, and cells consume oxygen every moment, and the body can only function normally when there is an adequate supply of oxygen. The human body's internal oxygen supply is entirely obtained through breathing through the lungs. During the breathing process, the lungs not only take in oxygen, but also expel carbon dioxide metabolized from the body. It can be thought of this way: the lungs are the transit station for gas exchange in the body. The volume of this transfer station directly determines the amount of gas exchange during each breath and is the most intuitive and objective indicator for testing lung function. A low vital capacity test value (compared with the normal value) may indicate that the body's ability to absorb oxygen and expel waste gas is poor. The body's internal oxygen supply is insufficient, and some of the body's functions cannot function normally. Once the body needs to consume a large amount of oxygen (such as long-term study, work, and strenuous exercise), there will be a serious shortage of oxygen supply, leading to adverse reactions such as headache, dizziness, chest tightness, mental depression, inattention, memory loss, insomnia, etc. This not only affects work and study, but also causes many irreparable losses to physical health.

The amount of air that can be exhaled after taking a deep breath is called vital capacity. The volume of gas in the lungs varies with the depth of breathing. The amount of gas inhaled and exhaled each time in a normal state is called tidal volume; if at the end of a normal inhalation, one exhales as hard as possible to the limit, the amount of gas inhaled in addition to the tidal volume is called supplemental inhalation volume. Therefore, vital capacity is equal to the sum of tidal volume, inspiratory reserve volume, and expiratory reserve volume; it represents the maximum volume of air in one breath and reflects the potential and adaptability of lung ventilation function. The calculation formula for vital capacity of primary school students aged 6 to 14 is as follows:

Male vital capacity: (70.7 × age + 1 106) × body surface area

Female vital capacity: (73.47 × age + 945) × body surface area

The above is my opinion on this issue. If a girl has the above problems, she needs to take timely treatment to ensure her health and avoid dangerous situations caused by the above problems. If problems occur, she should take timely treatment.
