For petrochemical workers, it is necessary to fully understand and follow the principles and points of physical examination to achieve efficient and reasonable inspection.

1. Select the examination items that suit you.

In the process of physical examination, some necessary routine examinations are essential. However, some items, such as CT, X-ray, magnetic resonance, gastroscope and unnecessary blood drawing, can be omitted. Usually these items are used to diagnose diseases. Therefore, it should not be a routine inspection item.

2. Pay attention to check the indications and contraindications of the project.

First of all, we should have a general understanding of the physical examination items that need to be carried out, because both general health examination items and special physical examination items often have their corresponding indications and contraindications. Knowing these contents, you can judge whether it is necessary for you to do this examination, or whether your physical condition can accept this examination.

3. Check it reasonably according to your own situation.

Because of age, gender, physical fitness and other factors, everyone's physical condition is quite different. Therefore, the physical examination should also formulate and issue targeted key inspection items respectively. For example, 70-year-old retirees will definitely have their corresponding physiological conditions: renal insufficiency, changes in cardiopulmonary aging, arteriosclerosis and other common diseases of the elderly. Then you don't have to check this kind of project. In addition, there are many examination items with similar functions, such as ordinary electrocardiogram and high-frequency electrocardiogram. Such examination items can be selected in a targeted manner, and it is not necessary to do all of them to avoid repeating the examination.

4. Treat the physical examination correctly

The purpose of physical examination is to help people understand their physical health status and take it as a powerful basis for taking reasonable health care measures, which can only be used for doctors' reference, but not as evidence for their diagnosis of diseases. For example, the change of ST segment of ECG is diagnosed as coronary heart disease. This is not only unscientific, but also causes psychological pressure to candidates, thus violating the purpose of physical examination.
