The 24-hour ambulatory blood pressure monitoring is not to be taken off after being worn and is to be completed for 24 hours. The 24-hour blood pressure monitoring is used by doctors to assess the patient’s hypertension or hypotension according to the pattern of diurnal variation of blood pressure within 24 hours, so as to select targeted medication for treatment. It is best to wear the cuff for the full 24 hours and not to take it off without special circumstances, so as not to affect the results of the blood pressure measurement. If the cuff inflates during wear and causes the patient strong discomfort, it should be removed only after contacting the doctor and obtaining his/her consent. Avoid strenuous exercise while wearing the 24-hour ambulatory blood pressure monitor. When the cuff inflates during recording, stop the activity and place your hands vertically on both sides of your torso. Do not touch the buttons during measurement, and do not remove the batteries. Stay away from places with strong electronic interference and high voltage as far as possible. The specific treatment should follow the doctor’s advice.
