Ambulatory blood pressure: ambulatory blood pressure recorder


ambulatory blood pressureIt is a method of using a dynamic blood pressure recorder to measure a person's blood pressure within a certain period of time within 24 hours of day and night, called dynamic blood pressure. Ambulatory blood pressure includes systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, which is greater than or equal to 21.3 / 12.6kPa(160 / 95mmHg) or/and 18.7 / 12.0kPa( 140 / 90mmHg) percent.

Ambulatory blood pressure recorder is divided into two types: cuff type and finger cuff type. The cuff ambulatory blood pressure recorder consists of a transducer, a miniature recording box and a recovery system. The cuff can be periodically inflated, the brachial artery blood pressure can be measured, and the data can be automatically stored. 200 many blood pressure values can be stored in a day, and then the blood pressure values can be analyzed and printed in the recovery system of the entire machine. The main disadvantage of this device is that the cuff is often inflated and deflated, which can affect the patient's rest at night. In addition, physical exercise may interfere with the measurement and make the measurement results inaccurate.

The second is the cuff type dynamic blood pressure recorder. Some people have pressure sensors attached to their fingertips to measure arterial blood pressure in their left finger. When measuring with this sphygmomanometer, although it does not affect rest and can measure blood pressure in a standing position, more movement of the finger may cause more blood pressure errors. Another type of finger-cuff ambulatory blood pressure meter is to measure pulse transit time, which is input into a computer to calculate systolic, diastolic and mean blood pressure. It is not affected by position and movement of the limbs. The patient has no feeling during the measurement, so it does not affect the patient's rest. It can be measured more than 2000 times a day, so a series of blood pressure measured with this sphygmomanometer can truly reflect the patient's blood pressure changes in daily activities.
