V Series Operating Instructions xxiii
Cautions Introduction
CAUTION: The V 12/V 21 may not meet its performance specifications if stored or
operated outside of specified temperature and humidity ranges. If
abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the V 12/V 21.
CAUTION: Do not measure NIBP on patients with sickle-cell disease or on the limb
where skin damage has occurred or is expected.
CAUTION: Do not use the NIBP cuff on a limb with an intravenous infusion or
arterial catheter in place. This could cause tissue damage around the
catheter when the infusion is slowed or blocked during cuff inflation.
CAUTION: Observe caution on all patients (Neonates, Pediatrics, and Adults) when
NIBP is set to the Stat mode and when using the 1 minute interval.
When the NIBP Stat is selected, the V 12/V 21 continually takes
continuous blood pressure readings. As a safety precaution, a limit is
placed on NIBP Stat mode. In NIBP Stat mode, after 5 minutes or 10
readings, the NIBP reverts to the previous interval setting. As a safety
precaution in 1 minute mode, a mandatory 30 second deflation period
between measurements is added. Reports have been made of nerve
injury occurring during use of automatically cycled blood pressure
cuffs
.
CAUTION: To monitor and trend NIBP measurements, the NIBP tile or NIBP list tile
must be configured to display. No NIBP monitoring occurs unless one of
these tiles are configured to display.
CAUTION: When equipped with Nellcor® SpO
2
, use only Nellcor oxygen
transducers including Nellcor Oxisensor® and OxiMax® patient
dedicated adhesive sensors. Use of other oxygen transducers may
cause improper oximeter performance.
CAUTION: When equipped with Masimo SET® SpO
2
, use only Masimo SET Oxygen
Transducers including Masimo SET LNOP® and LNCS® Patient Dedicated
Adhesive Sensors and Masimo SET PC Series Patient Cables. Use of
other oxygen transducers may cause improper oximeter performance.
CAUTION: When a battery has visual signs of damage, or no longer holds a charge,
it should be replaced. Remove the old battery from the monitor and
recycle it according to the hospital policy. To dispose of the batteries,
follow local laws for proper disposal.
CAUTION: Replace Li-Ion batteries with P/N 0146-00-0091-01 ONLY.
CAUTION: Some pacemakers may contain a respiratory sensor that may produce
artifact on an ECG waveform.
CAUTION: Tissue damage or inaccurate measurements may be caused by incorrect
SpO
2
sensor application or use, such as wrapping too tightly, applying
supplemental tape, failing to inspect the sensor site periodically, or
failing to position appropriately. Carefully read the sensor directions
for use, the V 12/V 21 Operating Instructions, and all precautionary
information before use.
CAUTION: Inaccurate SpO
2
measurements may be caused by:
• Incorrect sensor application or use
• Significant levels of dysfunctional hemoglobins, (e.g.,
carboxyhemoglobin or methemoglobin)
• Intra-vascular dyes such as indocyanine green or methylene blue
