9.4 NIBP Monitoring
To obtain accurate measurements, the following operating steps need to be observed:
1. Ensure the patient position in normal use, including
Comfortably seated or lie flat, legs uncrossed;
Feet flat on the floor;
Back and arm supported;
Middle of the cuff at the level of the right atrium of the heart;
During the measurement, relax as much as possible, neither talking nor applying external
pressure against the cuff.
2. Plug in the air hose and switch on the system.
Apply the blood pressure cuff to the patient's arm or leg following the instructions below.
Cuff Usage
Ensure that the cuff is completely deflated.
Apply the appropriate size cuff to the patient (About the cuff size selection, please refer
to Section Accessories), and make sure that the symbol "Φ" is over the artery. Ensure
that the cuff is not wrapped too tightly around the limb. Excessive tightness may cause
discoloration and eventual ischemia of the extremity.
3. Check whether the patient type is appropriately selected. Access PATIENT SETUP menu
from SYSTEM MENU and pick PAT TYPE item and select the required patient type.
4. Select a measurement mode in the NIBP SETUP menu. Pick the INTERVAL item for
MANUAL or set the interval for auto measurement; or select the CONTINUAL mode.
5. Press the NIBP START/STOP on the front panel to start a measurement. You can also stop
this measurement by this button.
