CONDUCTIVE CONNECTIONS. Extreme care must be exercised
when applying medical electrical equipment. Many parts
of the human/machine circuit are conductive, such as
the patient, connectors, electrodes, transducers. It is
very important that these conductive parts do not come
into contact with other grounded, conductive parts when
connected to the isolated patient input of the device. Such
contact would bridge the patient's isolation and cancel the
protection provided by the isolated input.
DELAYED ASYSTOLE ALARM. The pulsatile heart rate may
have a slower response time than the electrical heart rate
where there is a low perfusion patient condition. When using
the IntelliRate feature in this situation, the device may delay
calling an ASYSTOLE patient alarm. The user may elect to turn
the IntelliRate feature off for patients at risk of these events,
otherwise patient treatment may be delayed. Such patients
should always be kept under close observation.
NOISY ECG alarm. The Noisy ECG alarm indicates that the
system is no longer monitoring ECG and there may be no HR
high, HR low, Tachy or Brady alarms. If you adjust the alarm
priority level lower than the default value, keep the patient
under close surveillance.
ARRHYTHMIA PAUSED alarm. The Arrhythmia paused alarm
indicates that the system is no longer monitoring ECG and
there may be no HR high, HR low, Tachy or Brady alarms.
If you adjust the alarm priority level lower than the default
value, keep the patient under close surveillance.
INACCURATE HEART RATE INDICATION. The electrical and
pulsatile heart rate values provided by the various monitored
parameters (ECG, SpO , blood pressures) may differ markedly.
2
These differences may be due to underlying physiologic
conditions (e.g., electromechanical dissociation, pulseless
electrical activity, non-perfusing rhythms) or to inaccuracies in
the heart rate values caused by artifact, poor signal quality, or
arrhythmias. The user may elect to turn the IntelliRate feature
off for patients at risk of these events, otherwise patient
treatment may be delayed. Such patients should always be
kept under close observation.
ELECTRODES. Whenever patient defibrillation is a possibility,
use non-polarizing (silver/silver chloride construction)
electrodes for ECG monitoring. Polarizing electrodes (stainless
steel or silver constructed) may cause the electrodes to retain
a residual charge after defibrillation. A residual charge will
block acquisition of the ECG signal.
DEFIBRILLATOR PRECAUTIONS. Patient signal inputs labeled
with the CF and BF symbols with paddles are protected against
damage resulting from defibrillation voltages. To ensure
proper defibrillator protection, use only the recommended
cables and leadwires.
