If the pulmonary function test is normal, do you need to do it again?

Some parents think that pulmonary function tests.

It's redundant, or you don't need to do it again if you think it's normal to do it once.

However, pulmonary function tests are done in asthma.

It is not only valuable for the diagnosis and evaluation of asthma, but also an important reference for doctors to judge the severity and effect of the disease.

In the process, the doctor conducts a pulmonary function test on the patient to evaluate the effect and adjust the regimen and drug dosage in time.

Children with asthma are generally recommended to have a follow-up visit once every 1-3 months, and if possible, pulmonary function tests can be performed at each follow-up visit. Pulmonary function test is convenient to assess the degree of asthma control, if the child's drug inhalation method is incorrect, affecting the recovery of the small airway, the doctor can also use the results of the pulmonary function test to find the problem in time, and correct the child's medication in time, which is beneficial to the child with asthma**.

Summary. Hello dear, happy to answer for you; Can you do a pulmonary function testThe answer is: kiss Yes, you can check the lungs, you can do chest imaging tests, pulmonary function tests, blood tests, etc.

1.Chest imaging. Lung imaging tests include chest CT scan, chest X-ray, chest MRI and ultrasound.

2.Pulmonary function tests. Pulmonary function tests are commonly used in the diagnosis and treatment of respiratory diseases, including spirometry, bronchodilation test, bronchial provocation test, etc.

Generally, such examinations can be used to determine whether the patient has chronic bronchitis, emphysema, bronchial asthma, etc.; 3.Blood tests. It is mainly to check the blood routine, C-reactive protein and other indicators, and whether the patient has infection can be judged through the indicators.

Pulmonary function tests.

Blood tests. It is mainly to check the blood routine, C-reactive protein and other indicators, and whether the patient has infection can be judged through the indicators.

Many patients with respiratory disease should be familiar with pulmonary function tests. Pulmonary function tests are an important test for respiratory diseases. This test is important for the early detection of lung and airway lesions, the assessment of disease severity and prognosis, and the evaluation of the efficacy of drugs or other methods.

It is effective in detecting early lesions in the lungs and airways, identifying the cause of dyspnea, and determining the location of airway obstruction. No matter how old you are, you should test your lung function. Recurrent cough and sputum production indicate airway or lung disease, which may reduce lung function.

If chest tightness and shortness of breath occur after activity, especially if it gets worse gradually, it is necessary to check lung function if there is a problem with lung function. In particular, older people often don't pay enough attention to this, citing shortness of breath when walking and climbing stairs as the cause of their age. If you are exposed to polluted gases and dust in your work environment, it can lead to occupational lung disease and reduced lung function.

Regular lung function checks in patients with bronchial asthma and chronic obstructive pulmonary disease can not only reflect the condition but also provide further guidance on medications**. Lung function should be checked for all conditions that may affect lung ventilation. Pulmonary function tests are of greater value in the diagnosis and differential diagnosis of common respiratory diseases such as asthma, chronic obstructive pulmonary disease (emphysema), respiratory foreign body aspiration, bronchitis, pneumonia, and pleurisy.

Patients with suspected asthma must stop taking anti-asthma medications before the examination. Please follow your doctor's advice when to stop the drug. Patients with uncontrolled hypertension and heart disease cannot have pulmonary function tests.

Patients with ventilatory dysfunction should be cautious in bronchial provocation testing. In recent weeks, patients with massive hemoptysis, pneumothorax, giant bullae that are not ready for surgery, and those with unstable cardiac function, should be careful to perform pulmonary function tests that require forced expiration. Bronchodilators are contraindicated in patients with allergies.

Bronchial provocation testing is contraindicated in patients with laryngeal or vocal cord edema and moderate or greater ventilatory dysfunction.

According to statistics, the incidence of chronic obstructive pulmonary disease in China is about 8%, especially for smokers over 40 years old, the incidence of chronic obstructive pulmonary disease is relatively high. However, most patients with early COPD have no obvious symptoms, and lung function is impaired in 50% of patients at the onset of symptoms; Once you have a cold, it's too late to diagnose it. Recommended for smokers over 40 years of age or patients with chest suffocation and shortness of breath.

Get your lung function tests done as soon as possible and as soon as possible**.

I think that some people who smoke a lot, or workers who work in special environments, and their frequent exposure to some dust and polluted gases may cause some diseases in the body that reduce lung function; All bronchial dilator drugs should be stopped for the first three days of pulmonary function tests, and pulmonary function tests should not be done in patients with cardiovascular disease or cardiac insufficiency.

People who often cough up, cough up blood, have poor breathing, have lung diseases, bronchitis, asthma and other diseases need to have pulmonary function tests; When doing a pulmonary function test, you need to pay attention, you must not be nervous, you must do it according to the doctor's instructions, and do not put too much pressure on yourself.

People who need to have pulmonary function tests include dust exposure, long-term smoking, air pollution, sputum production, and chronic cough; When doing the pulmonary function test, you should maintain a normal state of mind, relax your mind, ensure a reasonable diet, and take the test in a full stomach.

Disease analysis: If the elderly have lung infection, the specific survival time depends on the specific situation and the effect of the disease, and the severity of the condition to be clarified. For ordinary lung infections, it is necessary to find the targeted sensitive bacteria, and rationally apply antibacterial drugs for conditioning, which can soon reach the best situation, and you can choose to carry out sputum culture to find the right sensitive bacteria.

Hello: The symptoms you expressed are common clinical manifestations of respiratory diseases, which cause more **, such as bronchiectasis, tuberculosis, lung or respiratory tract tumors, lung or bronchial inflammatory lesions, throat inflammation, etc. Lung examination is mainly done CT or MRI of the lungs, in addition, other auxiliary tests may be required according to the condition, such as erythrocyte sedimentation rate, blood routine, sputum culture, bronchoscopy, etc.

Pulmonary function tests should be performed for any condition that may affect the ventilatory 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.

Different respiratory diseases present differently on pulmonary function tests.

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.

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.
