Description
Blood pressure indirect measurement method, divided into auscultation method and oscillogram method.
Auscultation method has its inherent shortcomings: first, there is always a debate on whether diastolic blood pressure corresponds to the fourth phase or the fifth phase, which causes a large discrimination error. The second is to distinguish systolic blood pressure and diastolic blood pressure by listening to Kirschner's voice. The readings are affected by a series of factors such as the doctor's mood, hearing, environmental noise, and the tension of the test subjects, which are easy to introduce subjective errors and difficult to standardize.
Although the electronic blood pressure monitor made of the principle of auscultation has realized the automatic detection, it still has not completely solved its inherent shortcomings, that is, the error is large, the repeatability is poor, and it is easy to be disturbed by noise.
It must be pointed out that from the perspective of measurement principle, there is no question which of the two indirect measurement methods is more accurate.
The measurement method of arm type accurate blood pressure monitor is similar to the traditional mercury blood pressure monitor measuring the brachial artery, because its arm band is put to the upper arm, its measurement stability is better than wrist blood pressure monitor, more suitable for older, irregular heart rate, diabetes caused by peripheral vascular aging and other patients.
The Brav arm type accurate blood pressure monitor captures your readings as well as any irregular heart beats and body movements during measurements.
The blood pressure monitor features one-click use and body motion detection, helping to ensure easy use and accurate readings.
The cuff of the Brav arm type accurate blood pressure monitor fits all large standard adult upper arms with a circumference of 8 "to 17". This soft, wide range D-loop cuff is designed for more comfortable measurements.
The correct use of arm electronic BP-monitor
Sit for a few minutes, then slip your arm into the armband and bind it
Measuring with bare arms or wearing only thin clothing;
Arm band binding strength is moderate, to be able to put a finger is appropriate;
The center of the arm band is at the same height as the heart;
The lower arm band is 1-2cm from the elbow joint.
Press the user key to automatically start the measurement
When measuring, the palm is relaxed, palm up;
Stay calm and relaxed during the measurement;
Do not talk or move your body during measurement.
The results show either manual shutdown or automatic shutdown
After the measurement, the blood pressure value and pulse value are displayed.
In special cases, there will be arrhythmia.
