spirometry body mass index

The vital capacity body mass index is one of the composite indicators of anthropometric measurements. Mainly through the ratio of the human lung capacity to body weight, that is, the relative value of lung capacity per 1kg body weight reflects the correlation between lung capacity and body weight, for objective quantitative comparison analysis of individuals and groups of different ages and genders. It has a certain reference role in the selection of athletes in oxygen metabolism projects and the comprehensive evaluation of students' physical fitness. Its calculation formula is: lung capacity / body weight. Unit of measurement: milliliters (ml) of lung capacity and kilograms (kg) of body weight. Basic Information Specialist Category: Respiratory Examination Category: Other Inspections Applicable gender: whether men and women apply fasting: not fasting Tips: Before the check, the taboo is poor, the diet is not proper, and the fatigue is excessive. Normal value No specific standards. Clinical significance Abnormal results The low vital capacity detection value (compared with the normal value) indicates that the body's ability to take oxygen and exhaust gas is poor. The oxygen supply inside the human body is not sufficient, and some work of the body cannot be normal. Once the body needs a lot of oxygen consumption (such as long hours of study, work, strenuous exercise), there will be a serious shortage of oxygen supply, resulting in such as headache, dizziness, chest tightness, listlessness, lack of concentration, memory loss, insomnia Other adverse reactions, this will not only affect learning and work, but also cause many irreparable losses to health. People who need to be checked A population of full physical and physical tests. Low results may be diseases: lobar pneumonia, aspiration pneumonia, emphysema precautions Taboo before the examination: poor rest, improper diet, excessive fatigue. Requirements for inspection: Actively cooperate with the doctor's work. Inspection process The body weight and vital capacity were measured first, and then the ratio of body weight to vital capacity was calculated. Not suitable for the crowd Generally there are no people who are not suitable. Adverse reactions and risks Generally no adverse reactions.
