28 Vital Signs Monitor
WARNING: Do not place the cuff on any extremity being used for SpO
2
monitoring. Cuff inflation during
an SpO
2
measurement will cause inaccurate SpO
2
results.
Wrap the cuff snugly with room between the cuff and the arm for not more than one or two fingers.
Excessive tightness may cause venous congestion and discoloration of the limb. If the cuff is
wrapped too loosely, it cannot be inflated properly and the measured values may be in error.
It is best to place the cuff on a bare arm. Clothing may interfere with measurement accuracy.
When wrapping the cuff, observe the mark on the cuff which must be placed over the brachial
artery. Ensure that the hose is not twisted, kinked or compressed, as this may cause measurement
errors.
Manual Mode Blood Pressure
Blood pressure measurement may be initiated on demand by the operator. This is the manual
mode of operation.
To operate the blood pressure monitor in manual mode, follow this procedure:
1. Ensure that the blood pressure cuff is properly sized and wrapped around the patient's upper
arm (or alternate site, as necessary).
2. With the Monitor powered up, press the START button. The Monitor will inflate the cuff to the
default pressure preset level.
NOTE: If a BP measurement is initiated within one minute of a prior BP measurement, the
Monitor will inflate to a level which is 40 mmHg above the previous systolic reading.
3. The systolic display will show the pressure in the cuff as the blood pressure determination is
being made.
4. When the measurement cycle is complete an audible tone will sound and the systolic, diastolic
and pulse rate* display will show the values of the reading.
5. The reading will be displayed for two minutes, and then this display will be blanked. The reading
may be recalled at any time prior to the next BP determination by pressing the REVIEW button.
6. Pressing CANCEL at any time during a blood pressure determination will cause the
determination to be aborted, and the cuff to rapidly deflate.
*Pulse rate, as determined from the blood pressure measurement method, will be displayed with
the BP reading only if SpO2 option is absent or disabled. If the SpO2 function is operational, all
pulse rate determinations will come as a result of the SpO2 measurement method.
Automatic Mode Blood Pressure
Blood pressure measurements may be automatically initiated at operator programmed time inter-
vals.
To operate the blood pressure monitor in automatic ("Auto") mode, follow this procedure:
1. Ensure that the blood pressure cuff is properly sized and wrapped around the patient's upper
arm (or alternate site, as necessary).
