How do I self test my lung function and what is a pulmonary function test?

1. Exhale hard after inhaling enough, and see that you can exhale completely in a few seconds, often healthy people should be able to exhale 70%-80% in the first second, and should be able to exhale completely within three seconds. If the exhalation time is too long, it often indicates that the lung function is relatively poor.

2. There is also a breath-holding experiment, generally speaking, the longer the breath-holding time, the better your lung function, often more than 30 seconds, relatively speaking, the lung function is relatively normal.

3. You can do the test of climbing the stairs, climbing the stairs can often go to the fifth floor in a row, and the elderly can walk to the third floor in a row, if there is no obvious shortness of breath or need to rest, it should be said that the lungs are relatively healthy. If young people climb to the fifth floor and do not have obvious shortness of breath, it should be said that they are relatively healthy.

In daily life, we can also perform lung function self-test through a few simple small movements.

1. Blowing candles.

Light a match and blow as hard as you can, if it can't be blown out at a distance of 15 cm from your mouth, it means that there is a problem with your lung function; If the distance is 5 centimeters.

It can't be blown out, indicating that the lung function is very poor.

2. Stair climbing method.

Ascending to the third floor at an unhurried pace and not feeling obvious shortness of breath and chest tightness indicates that the cardiopulmonary function is good.

3. Breath-holding method.

After inhaling deeply, holding your breath for 30 seconds indicates that your cardiopulmonary function is very good, and it is not bad if you can hold your breath for more than 20 seconds.

4. Small exercise test.

Run in place for a while to increase your pulse to 100-120 beats per minute, and if it returns to normal within 5-6 minutes after stopping activity, your heart and lung function is normal.

The lungs are an important organ of the respiratory system, it is the exchange place of gases inside and outside the body, the human body inhales oxygen, and then exhales carbon dioxide, and maintains the normal body system of the human body over and over again. If people with insufficient lung qi, not only other organs will be affected, such as some people with irregular heart rate, high blood pressure and blood lipids, and weak resistance are closely related to lung function, in daily life, we can self-test lung function by climbing stairs, blowing balloons, swimming and other methods, so that we can know in advance whether our lung function is normal.

How to self-test your lung function

The first method is observation. Observe yourself for symptoms such as cough and asthma, if a simple small exercise causes a large exhalation and inhalation, causing difficulty breathing, then it is a clear indication that your lung function is not good, in order to avoid the severity of lung problems, you should seek medical attention in time. The second way is to blow up the balloon.

If you can blow a balloon without doing strenuous exercise, if you can blow it up easily, it means that your lung function is not bad, and if you can blow about 3 balloons in a row, it means that your lung function is great.

The third way is to climb the stairs. In general, the building of a normal residential building climbs to the third floor and still has no obvious wheezing manifestations, indicating good lung function. The fourth way is to hold your breath. Try to hold your breath after a short rest, if you can hold your breath for 25 seconds, your lungs are doing well.

How to improve lung function

Lung function is an important part of the human body, if you want to improve lung function, you should insist on exercising for a long time, for example, do more aerobic exercise, jogging or pedaling bicycle, swimming, badminton, etc., you can also do a chest expansion exercise, lifting dumbbells, long-term persistence, will strengthen the respiratory muscles, improve respiratory function, improve lung function. In terms of exercise, the next thing is to increase nutrition, and people with poor lung function can eat more foods that moisten the lungs, such as winter pears, honey, and grapefruit. As long as the lungs function normally, our body will become healthier and healthier, and every day will be full of vitality, and work and study will be more efficient.

The easiest way to do this is to hold your breath. If you can hold it for 40 seconds, you will be healthy, if you can't reach 30 seconds, you will have problems, and if you can hold it for more than 50 meters, it will be very good.

You can check it often, preferably once a year or so, to have a particularly good guidance. You can also see if you will cough often in your life and whether you will have shortness of breath.

You can measure your lung capacity, or check your body's condition, you can also climb the stairs to measure, and you can also breathe self-test, and learn to test your own way.

Pulmonary function tester is mainly a medical device that measures the volume of air inhaled and exhaled in the lungs. Pulmonary function tests can be performed and lung health can be tracked, and commonly used pulmonary function test parameters including FVC, FEV1, FEV1 and FVC can be measured.

It can be used for follow-up and health management of patients diagnosed with asthma, chronic obstructive pulmonary disease (COPD), cystic fibrositis (CF), etc.; It can be used in lung surgery or lung transplant patients to observe drug reaction and human rejection; Patients can be reminded to take medication regularly, do pulmonary function tests regularly, and do lung breathing exercises prescribed by the doctor regularly; Inspection records and graphs can be exported for long-term monitoring.

Pulmonary function tests are reliable indicators of lung function in normal people. It can make accurate pulmonary function assessment in patients with chronic bronchitis, obstructive emphysema, and abdominal and thoracic surgery. Pulmonary function tests plus provocative inhibition test are the main basis for diagnosing bronchial asthma and are also objective indicators for evaluating the efficacy of asthma.

The lungs come with oxygen inhaled from the respiratory tract and at the level of the lungs at the source level with the dui from the blood

The ability of carbon dioxide to carry out gas exchange.

DAO, which is commonly referred to as lung function. Pulmonary function test is a method that uses advanced computer technology and modern respiratory physiology to measure the ventilation and ventilation function of the examinee through pulmonary function instruments. :

1. Patients with the following chronic lung diseases: 1. Lung infection 2, chronic obstructive pulmonary disease 3, chronic bronchitis 4, various asthma 5, emphysema 6, bronchiectasis 7, allergic rhinitis 9, pulmonary interstitial fibrosis 10, sleep-disordered breathing;

2. Patients with connective tissue diseases, such as lupus erythematosus, sarcoidosis, dermatomyositis, rheumatoid arthritis, Sjogren's syndrome, scleroderma, etc.;

3. Patients with various occupational lung diseases, such as silicosis, silicosis, pneumoconiosis, etc.;

4. Patients before and after thoracic and abdominal surgery or those who need general anesthesia for surgery;

5. Patients with the following diseases other than the lungs: diabetes, coronary heart disease, various anemias, muscle weakness, before and after radiotherapy and chemotherapy, etc.

6. Those who need physical examination or labor ability appraisal.

7. Special groups such as athletes, astronauts, and pilots.

8. Precautions for those who need to clarify the type of airway obstruction: 1. Be aware and be able to actively cooperate with the doctor to do inhalation and exhalation 2. The examinee needs to stop taking certain drugs that affect the examination according to the doctor's instructions 3. It is best to bring the results of previous pulmonary function tests and chest X-ray for comparison.

Doctor's Lecture: Pulmonary function test is one of the necessary tests for respiratory diseases.

<>< 4 small ways to get a lung check-up at home.

1.Breath-holding self-test.

After taking a deep breath, hold it quietly, for more than half a minute, it means that the lungs are relatively healthy, and if it is less than 10 seconds, it is recommended to go to the hospital for a professional pulmonary function test.

2.Blow out candles or balloons.

Light a candle and try your best to blow it, but it can't be extinguished by blowing it 15 cm away from your mouth, saying that there may be a problem with lung function. When blowing up the balloon, it feels very strenuous, and it can't even be blown up or burst, so the lung power may be worse.

3.Climb stairs.

If you feel noticeable shortness of breath and chest tightness when you go up to the third floor at an unhurried pace, your lungs may not be functioning properly.

4.Observational method.

If you notice cyanosis of your lips, a dull complexion, and retraction of breathing (a significant depression in the suprasternal, supraclavicular fossa, and intercostal space during inspiration), you have inadequate lung function. It is recommended that you go to the hospital for relevant examinations in time.

The above self-test actions are only used as a reference for a preliminary understanding of lung function status, in order to get accurate scientific results, you need to do a pulmonary function test through the testing instrument.
