SYMBOL

GENERAL

This instruction manual is intended to assist the user for safe and efficient operation of the automatic digital blood pressure monitor (hereinafter: device) model UAM-720. The device must be used in accordance with the procedures described in the manual. It is important to read and understand the entire manual. especially the section <Tips for taking blood pressure measurement>.

This device is intended for the non-invasive measurement of systolic and diastolic arterial blood pressure and pulse rate in adults (age 15 and above). Consult the physician if measurement is taken in children or persons with arrhythmia as errors may occur.

PRINCIPLE OF OPERATION

This device adopts the oscillometric technology with Fuzzy Algorithm measuring the arterial blood pressure and pulse rate. The cuff is wrapped around the arm and automatically inflated by the air pump. 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.

Annotation: This device can not provide reasonable accuracy if used or stored in the temperature or humidity beyond the range stated in the section <SPECIFICATIONS> of this manual.

CAUTION: DO NOT USE THE DEVICE OUTDOORS

NEW TECHNOLOGIES USED

Fuzzy Algorithm is the processing algorithm taking into account of the speciality of individual heartbeats. which provides higher accuracy of measurement.

Software version: V1.1

TIPS FOR TAKING BLOOD PRESSURE MEASUREMENT

1. It is important to know that arterial blood pressure constantly changes. The level of the arterial blood pressure depends on many factors. Generally arterial blood pressure is lower in summer and higher in winter. Arterial blood pressure changes with atmosphere pressure and is affected considerably by many factors. e.g. exercise. emotional excitability. stress. meals. etc. Medicines. drinking. smoking affects greatly the level of individual blood pressure. When blood pressure is measured in hospital. the value is always higher than that at home. The reason is the tensity and such case is especially serious in given group patients. which is known as White coat effect’ medically. Blood pressure will raise in low tempera ture. so it is better to take blood pressure measurement in room temperature (approximately 20°C). If this device was stored in low temperature. it is necessary to leave it in room temperature for at least 1 hour. otherwise the measurement can be inaccurate. Blood pressure does vary with age and individual. and it is recommended to write down the readings in blood pressure record daily. then you can check with your doctor to find out what is “normal blood pressure” for you.

2. Take measurement under doctor's instruction for patients with cardio-vascular diseases.

Under no circumstances should you alter the dosages of any drugs prescribed by your doctor!

3. Accurate measurement of blood pressure may be difficult in arrhyth mia. premature beat. atrial fibrillation atreriosclerosis hypoperfusion diabetes pregnancy nephropathy. weak pulse. or in patients with obvious fluctuation of heart contraction rhythm. Please consult a qualified physician to interpret your blood pressure readings.

4. lt is necessary to keep quiet during measurement to get accurate readings. Measurement should be conducted in quiet environment at room temperature. Don't eat or smoke before a measurement.This device includes 1 upper arm cuff. Care should be taken to ensure that the cuff size is appropriate for the person whose blood pressure is being taken. Children and adults with cuff size fall outside the range of the cuff should select special size cuffs. Please contact the dealer to get these special size cuffs.
