Introduction Cautions
xxiv V Series Operating Instructions
• Exposure to excessive illumination such as surgical lamps
(especially ones with a xenon light source), bilirubin lamps,
fluorescent lights, infrared heating lamps, or excessive ambient
light. In such cases, cover the sensor site with opaque material
•Venous pulsations
•Electro-surgical interference
• Placement of a sensor on an extremity that has a blood pressure
cuff, arterial catheter, or intra-vascular line
• Nail polish or fungus
CAUTION: Prolonged and continuous monitoring may increase the risk of skin
erosion and pressure necrosis at the site of the sensor. Check the SpO
2
sensor site frequently to ensure proper positioning, alignment and skin
integrity at least every eight (8) hours; with the Adult and Pediatric re-
usable finger sensor, check every four (4) hours; for neonates and
patients of poor perfusion or with skin sensitive to light, check every 2 -
3 hours; more frequent examinations may be required for different
patients. Change the sensor site if signs of circulatory compromise
occur.
CAUTION: When cleaning SpO
2
sensors, do not use excessive amounts of liquid.
Wipe the sensor surface with a soft cloth, dampened with cleaning
solution. Do not attempt to sterilize.
CAUTION: A functional tester cannot be used to assess the accuracy of the pulse
oximeter probe or a pulse oximeter monitor.
CAUTION: Temperature probes are for single use only. Reuse may cause a risk of
contamination and affect the measurement accuracy. Destroy after
single use. Do not re-sterilize.
CAUTION: Federal (U.S.A.) law restricts this device to be sold by or on the order of
a physician.
CAUTION: Line Isolation Monitor transients may resemble actual cardiac
waveforms, thus inhibiting heart rate alarms. Check lead wires for
damage and ensure good skin contact prior to and during use. Always
use fresh electrodes and follow proper skin preparation techniques.
CAUTION: The V12/V21 monitor does not auto select the ECG lead set used. When
the patient's ECG cable is changed, it is essential to manually select the
appropriate lead set combination on the monitor. If this is not done,
other functions such as ST analysis, ECG Respiration, arrhythmia
analysis, ECG analog output, and Defib synchronization could be
affected. The following should always be performed after the ECG lead
set is changed:
• Manually select the appropriate lead set at the bedside monitor
via the user interface.
• Relearn ST and Arrhythmia analysis.
CAUTION: An error message(s) may occur when the bedside monitor’s manually
selected lead set and the attached lead set do not match.
CAUTION: When connecting a sampling line to the monitor, screw the sampling
line connector clockwise into the monitor CO
2
port until it can no
longer be turned to ensure that it is connected securely to the monitor.
This will assure that there is no leak of gases during measurement at
the connection point and that measurement accuracy is not
compromised.
