The 24-hour EEG is mainly used to detect the brain wave status of an individual during sleep and daily activities. When accompanying the patient, it is important to prevent the power cord from falling off during the test, reduce the use of electronic devices, rationalize work and rest, and adjust the diet. 1. Prevent the power cord from falling off: During the 24-hour EEG, the test equipment will be connected to the patient’s body, and the chaperone needs to pay attention to the wire connection of the EEG test equipment at the right time, so as to prevent the power cord from falling off and affecting the EEG test. 2. Reduce the use of electronic devices: the patient and the escort should reduce the use of electronic devices to prevent the signals from electronic devices from interfering with the EEG test. 3. Reasonable work and rest: the escort should pay attention to the daily work and rest of the test subject, and try to minimize the time he/she stays up late to prevent the test subject from being too tired, which may affect the test results. 4. Dietary adjustments: During the 24-hour EEG, the chaperone should adjust the patient’s diet and minimize the intake of stimulating foods to prevent interference with the EEG test. During the 24-hour EEG, the chaperone should pay attention to the patient’s personal condition and report any abnormality to the physician in time.
