Vital capacity (VC) refers to the total amount of gas that can be exhaled at a time when you try to breathe in. Adult men's vital capacity is about 3500-4000 milliliters, women are about 2500-3000 milliliters. The better the health is, the greater the vital capacity is.
Spirometer is a portable, hheld device for measuring your ability to exhalate from the lungs, can provide a correct data to reflect the ventilation of the trachea.
The importance of vital capacity:
The vital capacity of the lung is closely related to the human respiration. Physiological studies show that the organs, systems, tissues, organs of the human body
Spirometry (low values compared with normal values), indicating that the body oxygen uptake exhaust, the oxygen supply inside the body is not sufficient, once the body needs a lot of oxygen consumption situation (such as long time learning, work, strenuous exercise) there will be a serious shortage of oxygen supply, resulting in adverse reactions such as headache, dizziness, chest tightness, listlessness, inattention, memory loss, insomnia, this will not only affect the learning work, will cause many irreparable losses to health.
Usage method:
1. move the red movable buoy to the starting point.
2. use the mouth to hold the blue mouth, breathe deeply, hold the breath, blow out a breath, try to blow the buoy farther.
3.observe the location scale of floating buoys. The average adult men can reach 400L/min, the females can reach 350L/min, athletes vital capacity can reach 600-700L/min. (routinely calculated by milliliter ml. This lung activity meter is measured by ascending L. The conversion is as follows: if the scale you measure is 400L/min, the conversion to regular units is 4000ml/min.
How to use the peak flow meter?
① Dial the red pointer to the starting point of the ruler, the fingers of the peak current meter do not interfere with the activity of the pointer.
② St up breathe deeply.
③ The peak flow meter mouthparts into the mouth, lips tightly wrapped with mouthparts, forced a qui breath.
④ Write down the value of the red pointer dial the pointer to the starting point
⑤ Repeat the above action three times in a row take the best value. One should pay attention to is: with the greatest strength the fastest speed to exhale; lips tightly wrap the mouthparts, can not leak; don't blo the hole with the tongue, mouth parts.
If you want to repeat the test, please note that the red cursor pointer should be dialed to the lowest point of the scale before each test.
