Ручной монитор артериального давления с точным стетоскопом

1. Before the blood pressure meter is activated, check it first. The normal blood pressure meter usually refers to the “0” position. After the pressure, the reaction is flexible and can still return to the “0” position.
    2. Ask the person to be seated at the table and put the left arm on the table to maintain a comfortable posture.
    3. Adjust the arm and be at the same height as the heart. If the height is not enough, you can put a cushion under the arm.
    4. Flatten the arm band so that the middle part of the belt is facing the radial artery. The lower edge of the arm band is 2 to 3 cm on the elbow. The upper arm is not too tight or too loose. Generally, two fingers should be inserted under the sleeve. It is appropriate to avoid affecting correctness.
    5. Insert the stethoscope's head into the arm band and place it on the elbow's radial artery.
    6. Slowly inflate the inner band with the latex ball, and pay attention to the monitoring. When the pulsation of the radial artery disappears, the pressure is increased by 2.5 kPa-4 kPa (20 mmHg-30 mmHg) to stop pumping.
    7. After the pressure is stopped, the air in the arm band is slowly released at a rate of 0.3 kPa to 0.6 kPa (2 mmHg to 4 mmHg) per second, and the sphygmomanometer pointer is gradually lowered.
    8. The pressure value indicated by the hands when the first beating sound heard by the stethoscope during the descent is the systolic pressure.
    9. When the beat sound is gradually increased and then turned into a noise, then the tone suddenly becomes boring and gradually disappears. When the sound is not heard, it is diastolic pressure.
    When measuring blood pressure, it should be repeated 2 to 3 times, and the obtained readings are averaged as blood pressure values.
    The back of the sphygmomanometer case is equipped with a metal hook that can be hung on the arm band for easier reading.
    Blood pressure watch arm with Velcro, easy to attach
