ECG electrodes, choosing the position which is far away from the estimated Hertzian waves route, using larger
electro-surgical return electrodes and connecting with the patient properly.
% ECG leads may be damaged while using defibrillator. If the leads are used again, please do the functional
check first.
%
When removing the ECG cable, hold the head of the connector and pull it out.
%
When the monitor is inoperable due to an overload or saturation of any part of the amplifier, it will prompt
"Lead off" to remind operator.
?
No predictable hazard will be caused by the summation of leakage currents when several item of monitor are
interconnected.
?
Cardiac pacemaker pulse inhibition function is available while calculating heart rate, this function is always
effective on all filter settings for ECG monitoring and it can not be disabled by user.
3.4.2 Blood Pressure Cuff Connection
1. Connect the cable to the right-panel connector marked with the NIBP icon.
2. Select the appropriate cuff (see below) and wrap around the patient's upper arm.
Cuff requirements:
1) An appropriate cuff should be selected according to the size of the subject. The cuff width should be 2/3 of the
length of the upper arm. The cuff inflation part should be long enough to permit wrapping 50-80% of the limb
concerned.
Note: The size of the cuff selected should suit the patient while measuring.
% When putting on the cuff,, wrap it around the upper arm evenly to appropriate tightness.
2) Remember to empty any residual air in the cuff before the measurement commences.
3) Locate the cuff in such a way that the "φ" mark is at a location where the clearest pulsation of brachial artery is
observed.
4) The cuff should be tightened to a degree where insertion of one finger is possible.
5) The lower end of the cuff should be 2cm above the elbow joint.
3. Patient position while taking the blood pressure measurement for correct result:
Ø
Comfortably seated
Ø
Leg uncrossed
Ø
Feet flat on the floor
Ø
Back and arm supported
Ø
Middle of the Cuff at the level of the right atrium of the heart
