CAUTION:
Before each use, make sure that the monitor default alarm settings are appropriate for the
specific patient being monitored.
Pressing the front panel keyswitch with a sharp or pointed instrument may permanently damage
the keyswitch. Press the keyswitch using only your finger.
As with any non-invasive oscillometric blood pressure monitor, the accuracy of the
measurements obtained may be adversely affected by the presence of agents which alter the
patient’s cardiovascular system.
A calibration check is recommended once every year.
Do not alter the monitor's air hose. CAS Medical Systems cannot ensure proper monitor
performance if the tubing is altered. Modification of the air hose will void the warranty. Avoid
compression or restriction of pressure tubes.
If the cuff is applied on a limb being used for oxygen saturation monitoring %SpO

results will be
altered during each blood pressure measurement due to the occlusion of blood flow.
Inspect the monitor, air hose and sensors for any damage prior to operation. If any damage is
noted, the monitor should not be used until it has been serviced. The monitor should be
repaired only by personnel authorized to do so by CAS Medical Systems, Inc.
Use only CAS Medical Systems approved accessories and sensors to preserve the integrity,
accuracy and the electromagnetic compatibility of the monitor.
Consult a veterinarian for interpretation of blood pressure measurements.
The oximeter is factory calibrated to determine the percentage of arterial oxygen saturation of
functional hemoglobin.
Significant levels of dysfunctional hemoglobins such as carboxyhemoglobin or methemoglobin
may affect the accuracy of the measurement.
Cardiogreen and other intravascular dyes, depending on the concentration, may affect the
accuracy of the oximeter measurement.
Some sensors may not be appropriate for a particular patient. If at least ten seconds of one bar
pulses cannot be observed for a given sensor, change sensor location until this condition is
achieved.
If the monitor fails to respond, do not use it until the situation has been corrected by qualified
personnel.
