Normal range of vital capacity for children

Vital capacity refers to the maximum amount of oxygen people can exhale at one time, and it is closely related to human breathing. Studies have shown that various organs and systems in the human body consume oxygen all the time, and the human body can only survive normally when there is an adequate supply of oxygen. The lungs are the transformation station for gas exchange in the human body, and vital capacity directly determines the capacity of gas exchange in each breath. So, what is the average lung capacity of children? Let’s take a look at it together below.

Lung capacity also depends on age. There is no fixed value, so it is for reference only. Lung capacity refers to the capacity of the lungs. The standard is 4,300 ml for men in their twenties and 2,800 ml for women. Of course, lung capacity also varies with age... Normal value of lung capacity/weight: Male: 60 ml/kg or more, female: 50 ml/kg or more (Note: Lung capacity can be obtained through experience) (2) Lung capacity index = Lung capacity ÷ body surface area...

Life care:

You can just calculate it based on your normal weight. Condition Analysis:

The size of lung capacity is closely related to height, weight, and chest circumference, so the impact of these factors on the size of lung capacity should be fully considered when evaluating. Therefore, the lung capacity-weight index is used to evaluate students when scoring them.

Vital capacity to body weight index = vital capacity (ML) ÷ body weight

Suggestions:

The average reference value of primary school students' vital capacity: boys - 7 years old 1342ml, 8 years old 1496ml, 9 years old 1972ml, 10 years old 1843ml, 11 years old 2010ml, 12 years old 2200ml. Girls - 7 years old 1213ml, 8 years old 1354ml, 9 years old 1516ml, 10 years old 1685ml, 11 years old 1883ml, 12 years old 2077ml.

Life care:

Standard in primary school: 2200 for boys and 2300 for girls Condition analysis:

The size of lung capacity is closely related to height, weight, and chest circumference, so the impact of these factors on lung capacity should be fully considered during evaluation.

The above is the range of children's lung capacity, but this is just a fixed number. The specific number depends on each person's weight, height, and chest circumference. Everyone's situation is different. Moderate exercise every day can greatly help increase lung capacity.
