How to check brain waves

Many people need to do various examinations after they get sick, especially for cardiovascular and cerebrovascular diseases, which are more serious. Before the examination, you must pay attention to some matters before the examination to ensure the accuracy of the examination results. Brain wave examination is a common examination. You should try to relax before doing this examination. So how is the brain wave checked?

1. Please wash your hair the night before the examination and do not apply hair oil or hair spray.

2. Urinate before the examination, empty your bladder and relax.

3. When taking a waking brain wave test, try to get enough sleep the night before, do not take sedatives, and do not drink coffee or tea, etc., to improve the accuracy of the test. When taking a sleep EEG test, sleep less the night before, get up two hours earlier on the day or try not to take a nap at noon, so as to avoid not being able to fall asleep during the test.

4. During the examination, the technician will first clean the head skin with alcohol and fix the electrode wire with adhesive. After the inspector has properly placed the electrode wires, he will record the brain wave changes and operate the brain wave machine. This test is not uncomfortable.

5. During the examination, the patient must try to avoid moving the head and body, close his eyes, relax his whole body, and sit quietly for the examination. It will not cause pain and there will be no radiation side effects. Open and close your eyes and take deep breaths according to the instructions of the examiner to enhance the response of the radio waves.

6. The examination takes about 15-20 minutes (sleep EEG takes longer), and the examiner removes the electrode wires after the examination.

7. During the awake EEG test, the patient must remain awake and not doze off. When doing sleep EEG, patients should try to relax and fall asleep naturally.

8. After the examination, the patient can simply clean the glue on the head and then wash the hair after returning home.
