3 - Pressure adjustments. Option 3 of the main menu.
3.0 - Measuring the blood pressure.
This option lets you make as many blood pressure measurements as you wish.
It is essential to measure the height before the blood pressure measurement. Otherwise, the
readings of the blood preSsure will not be correct.
Proceed as follows:

3.1 - Calibration of the blood pressure.
The calibration is made in two steps:
·
The unit measures the value of the atmospheric pressure. In this moment, you must not apply any pressure to the
sensor, and the valve of the rubber bulb must be open.
·
A pressure of 200 mmHg is applied to the column and the unit measures its value.
Important Note:
The pressure adjustment is made automatically by the unit, by means of internal calculations, based on the indicated data.
To obtain a correct calibration, take the following into account:
·
Use a mercurial column or a manometer duly calibrated and certified.
·
Make sure that before inflating the mercurial column or manometer, the indication of the scale is 0 mmHg.
·
Make sure that there is no leakage in the tubing. It is also important (during the second step, when applying
pressure to the sensor) that the pressure is constant and stable during the process of adjustment.
·
If necessary, add a supplementary reservoir to the tubing so that the capacity of the air circuit is bigger and the
leakage is minimized.
Before, you must connect the manometer, with the valve open, to the pressure sensor so that the valve and the
compressor are out of the circuit. The resulting pneumatic system must be composed of the pressure sensor, the cuff
(used as reservoir) and the manometer.
