What to look for during a pulmonary function test, and what do you know?

I think we need to pay attention to spiritual problems, quality problems, health problems, moral problems, and psychological problems.

Pulmonary function tests are a physical and non-invasive test. In contrast to CT, pulmonary function tests are radiation-free, have little damage to the body, are painless, and rarely cause discomfort. It has the advantages of high sensitivity, convenient repeat detection, and easy patient acceptance, which can detect lung and airway lesions at an early stage.

Assessing the severity of the disease and diagnosing the location of the lesion are important for guidance.

At the same time, <> can also evaluate the best effect, avoid blind medication, and adjust the best plan in time. When it comes to lung function, many people may first think of lung capacity. Lung capacity is measured by the amount of time you hold your breath underwater, how many stairs you can climb in a single breath, and how many balloons you can blow without breathing.

But lung capacity is only one aspect of lung function. A comprehensive pulmonary function test also includes airflow limitation, expiratory flow measurement, airway resistance, and other indicators. The examining physician will determine lung function based on a number of lung function parameters based on normal height, weight, age, and sex.

Pulmonary function tests are mainly done by the patient's efforts and methods. In some cases (e.g., bronchial provocation test, bronchiectasis test), the drug should be stopped at a specified time before the test. Fasting is not required before pulmonary function tests, but strenuous exercise and cold air should be avoided for more than 2 hours, and smoking, coffee, and Coca-Cola should be avoided for more than 6 hours before certain pulmonary function tests.

For lung disease, a chest x-ray or chest CT should be done. A chest x-ray or chest CT is a routine method for diagnosing lung disease. Pulmonary disease in general requires testing, especially chest CT, which has a higher resolution than chest x-ray.

Lung function. Pulmonary function tests have important diagnostic value for chronic obstructive pulmonary disease, bronchial asthma and other diseases. In addition, lung function should be assessed preoperatively.

Blood gas analysis is a necessary test to diagnose respiratory failure. Bronchoscopy. Bronchoscopy is an effective method for diagnosing diseases such as tuberculosis, lung tumors, bronchiectasis, etc.

Proper pulmonary function tests can be effective in detecting signs of pulmonary obstruction, promptly** and monitoring the progression of the disease. Before the pulmonary function test, pay attention to maintaining normal life and hygiene, and be clean and clean. Relax and cooperate with the doctor to do a good check-up.

Different pulmonary function tests are done to understand specific conditions. For example, a chest X-ray can diagnose diseases such as pleural effusion, pneumothorax, pneumonia, and bronchopneumonia.

The precautions before pulmonary function tests are as follows:

Clause. 1. Pulmonary function should be judged whether the patient has to do pulmonary function, which is usually used for preoperative assessment and diagnosis of respiratory diseases, and some contraindications that cannot be done for pulmonary function should be excluded, such as hypertension, heart disease, acute myocardial infarction, massive hemoptysis, shock, consciousness disorder, etc. After excluding these diseases, patients should first pay attention to recording the drugs used by patients before doing lung function, especially inhaled drugs, and try to stop taking them.

Clause. 2. Eat as much as possible two hours before doing lung function, and try to avoid coffee, tea, tobacco and alcohol.

Clause. 3. Do not do strenuous activities half an hour before doing lung function.

Clause. Fourth, fully record the patient's data to avoid deviations in lung function.

Pulmonary function tests are used for early detection of lung and respiratory diseases such as chronic bronchitis, emphysema, and bronchial asthma. It is used to evaluate the patency of the airway, the size of lung capacity, and the tolerance of the patient's lung function to surgery or labor intensity.

Pulmonary function tests include breath test, excitation test, spirometry, and maximal ventilation measurement, all of which are tested by ventilation. The inspection of ventilation function is mainly based on the diffusivity of carbon monoxide. It can also be evaluated by blood gas analysis.

The lungs can be checked by means of instrumental testing, oral cavity testing, lung volume measurement, lung function checking, and ventilation function.

To check lung function, you need to go to the hospital for a systematic lung function test, which requires inhalation and exhalation on the instrument under the guidance of professionals, mainly to test the patency of the trachea, bronchi, lung capacity, and lung volume.

You can go directly to the hospital for examination, so that you can have a more comprehensive understanding of lung function, and you can choose to take a CT scan, or you can choose to do a B-ultrasound.

Nowadays, air pollution is getting more and more serious, and the lungs, as an important organ for breathing, must be protected. If you have problems with your lungs, then you will have a particularly hard time breathing, you will not be able to breathe enough oxygen, and some corresponding complications will occur. Therefore, everyone should have regular physical examinations, especially lung examinations, to see if their lung function characteristics do not meet the normal indicators.

If there is an abnormality in the test indicators of lung function, it is necessary to do an in-depth examination and prescribe the right medicine, so that the lungs can become healthier. What are the test indicators of lung function? What do you know?

We need to know that the examination of lung function is also one of the examinations of respiratory diseases, which is mainly used to check the smoothness of the patient's breathing, so there are many test indicators of lung function. I also searched the Internet and found that there were 8 kinds of lung function test indicators, so let's introduce them in detail. The first is a lung capacity test, which is to see how much lung capacity people have, and the second test is a lung capacity test, to see if people's lungs can fit more air.

The first test, which is the residual volume and maximum ventilation volume, is also very important. The fifth test is a test of the amount of forced breaths per second to see how much air people are able to breathe in in one second. The first type of test is a test of ventilation and ventilation to see if people's lungs are healthy.

The eighth type of examination is an early functional test, which is also very important to check the health of the blood vessels in the lungs.

It is especially recommended that people do a lung examination regularly, so that they can know whether their lungs are healthy, and if there is a problem, they can prescribe the right medicine, so that they can timely ** lung diseases. Therefore, doing a good job of examination is an important measure to prevent diseases, and you must not be afraid of spending money, and you must protect your body.

Pulmonary function test is a group of indicators commonly used to assist in the diagnosis of lung diseases, mainly including lung volume and ventilation function, ventilation function, diffusion function, small airway function, airway reactivity test, airway resistance test, etc.

1) Lung volume, the main basic indicators are tidal volume, expiratory volume, inspiratory volume and residual volume; Important indicators for judging lung damage, such as pneumonia, pulmonary edema, pulmonary interstitial fibrosis, lung tumors, etc.; Pleural effusion in the lungs, pneumothorax, chronic obstructive pulmonary disease, etc. Ventilatory function, including indicators such as minute ventilation, alveolar ventilation, maximal ventilation and temporal vital capacity, is the most common indicator for the detection of COPD and a sensitive indicator for early detection of small airway disease.

2) Ventilation function, to understand whether there is ventilation disorder, diffusion function abnormality, such as pulmonary fibrosis.

3) Airway reactivity test can be used as an important technical indicator for judging asthma and chronic obstructive pulmonary disease.

4) Airway resistance test is important in the diagnosis and efficacy evaluation of airway obstructive pulmonary disease.

All indicators of lung function were set according to the patient's age, gender, height, weight, etc. Before doing the pulmonary function test, it is necessary to pay attention to keeping the airway hygienic and clean, do not exercise vigorously, avoid shortness of breath, cooperate with the doctor during the examination, and follow the doctor's instructions as much as possible.

There are many kinds of indicators for pulmonary function tests, which can be divided into five categories, which are as follows:

Clause.

Clause. 5. Indicators of sleep monitoring.

Different lung function indicators represent different pulmonary dysfunction, such as temporal vital capacity can reflect whether the patient has restrictive ventilatory dysfunction, obstructive ventilatory dysfunction, or both restrictive and obstructive ventilatory dysfunction. Maximal forced ventilation per minute usually reflects whether the ventilatory reserve is able to tolerate segmentectomy, lobectomy, etc. Resting ventilation per minute can determine the patient's basal metabolism, vital capacity will show the degree of alveolar distension of the patient, and airway hyperresponsiveness and bronchodilation tests can determine whether there is reversible bronchospasm.

Diffusion function testing can determine whether the patient has diffusion dysfunction, and the percentage of residual air in the total lung volume can determine whether the patient has obstructive emphysema. If you have this symptom, determine which type it is, whether it is mild, moderate, or severe.

All in all, pulmonary function testing is a very important quantitative test index for lung function in clinical practice.

In addition, the medical equipment for detecting lung function is a pulmonary function tester, there are large lungs and small lungs, the main difference is that the large lung can detect diffusion function, and the main brand is German Jaeger. Small pulmonary function instrument, which is more common in major hospitals, has Anhui electronic pulmonary function instrument.

Lung volume, respiratory dysfunction, diffusion function, sleep monitoring, airway hyperresponsiveness, what I have learned are the main test indicators that are used to reflect whether the lungs are normal or not.

Lung volume , diffusion dysfunction , respiratory function , sleep monitoring , reversible bronchi , these are the most common indicators. It is also an important criterion for judging.

The top five common problems with lung function are as follows:

1. What is pulmonary function test? A: To put it simply, a pulmonary function test is a test technique that uses specialized medical equipment to measure the airflow velocity and airflow generated by the respiratory tract when a person breathes, so as to know whether the respiratory function is normal.

A: Pulmonary function tests are mainly used for the following purposes:

1) Early detection of lung and respiratory tract lesions.

2) Identify the cause of dyspnea and determine the location of airway obstruction.

3) Assess the severity of lung disease.

4) To assess surgical tolerance and the likelihood of postoperative complications.

5) Health examination, evaluation of labor intensity and tolerance; (6) Guardianship of critically ill patients.

Answer: (1) Pulmonary function test is a physical examination method, which does not cause any damage to the body, suffering and discomfort.

2) Restrictive lesions: refers to changes in lung ventilation that are restricted in respiratory movement, such as emphysema, pleurisy, and fluid pneumothorax, all of which have varying degrees of reduced lung ventilation.

3) Mixed lesions: refers to both obstructive and restrictive lesions, such as chronic obstructive pulmonary disease and advanced asthma, pneumoconiosis, pediatric bronchopneumonia, etc.

2) Pulmonary function test has the advantages of high sensitivity, convenient repeat testing and easy acceptance by patients.

3) Compared with chest X-ray, CT and other examinations, pulmonary function tests focus more on understanding the functional changes of the lungs, which is an important examination method for respiratory diseases.

A: Pulmonary function tests should be performed for any disease that may affect the ventilation function of the lungs. It is of great value in the diagnosis and differential diagnosis of common respiratory diseases such as asthma, chronic obstructive pulmonary disease (emphysema), airway foreign body aspiration, bronchitis, pneumonia, pleurisy, etc.

Answer: There are mainly (1) obstructive lesions: refers to changes in airflow obstruction due to narrowing of the airway caused by various factors, among which asthma is the most obvious.
