V Series Operating Instructions xix
Warnings Introduction
WARNING: Do not cut or remove any part of the sample line. Cutting the sample
line could lead to erroneous readings.
WARNING: Loose or damaged connections may compromise ventilation or cause
an inaccurate measurement of respiratory gases. Securely connect all
components and check connections for leaks according to standard
clinical procedures.
WARNING: To prevent possible electric shock, connect the V 12/V 21 system to a
correctly grounded mains connection.
WARNING: Do not rely exclusively on the audible alarm system for patient
monitoring. Adjustment of alarm volume to a low level or off may result
in a hazard to the patient.
WARNING: When the configured Audio Pause time period is set to Permanent, the
monitor does not provide any audible alarm tones even if a new alarm
occurs. Therefore the user should be careful about configuring the
Audio Pause to Permanent.
WARNING: Pacemaker patients’ rate meters may continue to count the pacemaker
rate during occurrences of cardiac arrest or some arrhythmias. Do not
rely entirely upon rate meter alarms. Keep pacemaker patients under
close surveillance. See the Product Specifications chapter of this
manual for disclosure of the pacemaker pulse rejection capability of
this instrument.
WARNING: Due to physiologic differences in the patient population, the V 12/V 21
may occasionally not alarm or may sound a false alarm for some
arrhythmia patterns. The arrhythmia analysis feature is intended to
detect ventricular rhythms only. High-risk patients should be kept
under close surveillance.
WARNING: During procedures employing electro-cautery, use currently
acceptable procedures to minimize conditions of the thermistor and
lead wires functioning as an alternate path for radio-frequency current
to return to ground, causing localized tissue burns. Procedures which
may minimize risk of electro-surgical burns are: keep both active and
ground electrodes of the electro-cautery system in close proximity so
that the temperature sensor is outside the radio-frequency current
field. Keep temperature monitor with its associated cables separated
from electro-cautery systems. Unusual, fast artificial variations in
temperature readings may occur with concomitant applications of the
electro-cautery system.
WARNING: Use only the specified temperature probe and probe cover. Using
another probe or probe cover, or not using a probe cover, may cause
damage to the monitor or failure to meet the declared specifications in
this manual.
WARNING: Temperature probes are sterile unless unit container is opened or
damaged.
WARNING: A hazard can exist if different alarm presets are used for the same or
similar equipment in any single area.
WARNING: The clinician should check that the current alarm settings on the V 12/V
21 monitor are appropriate prior to use on each patient.
WARNING: Setting alarm limits to extreme values can render the alarm system
useless.
