Preparation before use of a lung function detector

With the continuous development of social economy, pulmonary function detector has been more and more widely used in our daily life. However, we still need to make the following preparations before using pulmonary function detector.

1. Anthropometric measurements (age, height, weight, gender)

These factors determine the projected lung function, which is compared with people of the same age, height, weight, and sex. If the anthropometric value is miscalculated, it may lead to the deviation of the measurement result from the predicted value.

2. Understand medical history, medication history and other data

A history of dyspnea, post-exercise shortness of breath, cough, comorbidities, or pneumothorax may determine the safety of the test. It is also important to understand the patient's medication history. If the patient comes to the hospital breathless, he inhales bronchodilators before arriving at the hospital, and then checks the lung function after relieving the clinical symptoms, it is not the true result of lung function, so these influencing factors should be excluded.

3. Understand the purpose of the examination

To understand whether the pulmonary ventilation function is normal or whether the curative effect changes after treatment, the appropriate pulmonary function test can only be selected if the relevant purpose of the test is clear.

4. Understand indications and contraindications

Some contraindications, such as severe hypertension, acute myocardial infarction, or recent massive hemoptysis, may affect the patient's safety. Therefore, we need to understand the relevant contraindications and indications, so that we can do better in this aspect.

5. Instruct client to be familiar with inspection methods, steps and procedures

If the client is not familiar with it, he/she should be well instructed and trained to familiarize himself/her with the examination methods, procedures and procedures, so that he/she can better cooperate with the examination. At this time, the patient can be examined again, and the results will be reliable.

Practice listening to commands and breathing hard

If the client is instructed to breathe in but exhales; He breathed in when he was instructed to exhale. If they do not cooperate, the examination results will be counterproductive, leading to clinical misdiagnosis or missed diagnosis.
