3GENERAL Intended Use
This instruction manual is intended to assist the user in safe and efficient operation of the Upper Arm Automatic Digital Blood Pressure Monitor Model 1133 (hereinafter: device). The device must be used in accordance with the procedures described in this manual. It is important to read and understand the entire manual, especially the <Tips on taking blood pressure measurement> section.
This device is intended for the noninvasive measurement of systolic and diastolic arterial blood pressure and pulse rate in adults (age 15 and above). Consult your physician before using this device on children or persons with arrhythmia.
Principle of Operation
This device uses oscillometric technology with Fuzzy Algorithm to measure the arterial blood pressure and pulse rate. The cuff is wrapped around the upper arm and inflated automatically. The sensor of the device catches weak fluctuation of the pressure in the cuff produced by extension and contraction of the artery of the arm in response to each heartbeat. The amplitude of the pressure waves is measured, converted in millimeters of the mercury column, and is displayed by digital value.
Note: This device cannot provide reasonable accuracy if used or stored at temperature or humidity beyond the range stated in the <SPECIFICATIONS> section of this manual.
