Introduction: Contraindications
WARNINGS
Do not use the Dash 2500 Patient Monitor in the presence of
magnetic resonance imaging (MRI) devices. There have been
reports of sensors causing patient burns when operating in an
MRI environment.
To help prevent burns caused by unintended current return
paths with the use of high frequency (HF) surgical equipment,
ensure that the HF surgical neutral electrode is properly
connected.
To avoid personal injury, do not perform any servicing unless
qualified to do so.
Disconnect the power supply and remove the battery before
servicing.
To reduce the risk of electric shock, do not remove the cover or
the back of the unit. Refer servicing to a qualified service
person.
If the accuracy of any determination reading is questionable,
first check the patient's vital signs by alternate means, and
then check the Dash 2500 Patient Monitor for proper
functioning.
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 this manual
for disclosure of the pacemaker pulse rejection capability of
this instrument.
VENTRICULAR ARRHYTHMIA: The arrhythmia analysis program
is intended to detect ventricular arrhythmias. It is not designed
to detect atrial or supraventricular arrhythmias. Occasionally it
may incorrectly identify the presence or absence of an
arrhythmia. Therefore, a physician must analyze the
arrhythmia information in conjunction with other clinical
findings.
SUSPENDED ANALYSIS: When arrhythmia analysis is turned on,
conditions that suspend ECG processing also suspend
arrhythmia analysis. No detection of arrhythmia conditions or
associated alarms are given when arrhythmia analysis is
suspended. Arrhythmia analysis can be turned off by the user.
When it is, the message ARR OFF appears in the ECG waveform
area.
