Ambulatory blood pressure can be monitored by wearing a blood pressure recorder, which requires a blood pressure cuff to be attached and connected to the blood pressure monitoring device, and setting the appropriate interval frequency. Ambulatory blood pressure requires the examiner to wear a blood pressure recorder 24 hours a day, which continuously records blood pressure during the day and day and night. Generally, the blood pressure cuff is placed on the patient’s upper arm and adjusted to the appropriate tightness before measuring the blood pressure. The blood pressure cuff is then connected to the ambulatory blood pressure monitoring instrument, and the frequency of the interval is set on the instrument, for example, every 15 minutes, every 20 minutes, and every 30 minutes. It is recommended that dynamic blood pressure measurement can be performed under the guidance of a doctor, and the monitoring of patients’ dynamic blood pressure can observe the efficacy of medication, so that the medication can be adjusted in a timely manner. In addition, avoid taking off the cuff without authorization during ambulatory blood pressure measurement, and avoid bending the arm when the instrument is measuring blood pressure. If there is any abnormality, it is recommended to standardize the treatment under the guidance of the doctor.
