General warnings
These statements apply to all aspects of patient monitoring. Statements which apply
specifically to one aspect of monitoring, such as NIBP or SpO
2
monitoring, are presented
in the corresponding sections of the manual.
WARNING Many environmental variables, including patient physiology and
clinical application, can affect the accuracy and performance of the monitor. The
clinician must verify all vital-signs information prior to patient intervention.
WARNING Always check the patient mode (adult, pediatric, or neonate) when
monitoring a new patient. The patient mode determines default alarm limits and
internal algorithm settings. Make sure the monitor has settings that are
appropriate before monitoring the patient.
WARNING Make sure Acuity patients, and especially those prone to
arrhythmias, are kept under close surveillance. While monitoring patients with
Acuity, the clinician must review all clinical data before implementing therapy. As
with all computerized arrhythmia analysis systems, Acuity cannot replace skilled
care and proper surveillance by a clinician.
WARNING It is possible for Acuity alarms, alerts, or other events to go
unnoticed if clinical personnel are not present at Acuity or if interruptions occur in
power or system operations. To help reduce this possible occurrence, Acuity
must be installed with redundant power supplies and redundant means of
operator surveillance, such as secondary Acuity Central Stations and hallway
message panels.
WARNING The monitor might not meet its performance specifications if stored
or used outside the specified temperature and humidity ranges.
WARNING Use of respiration monitoring by impedance pneumography can
affect the operation of some pacemakers. If pacemaker operation is affected, turn
off respiration pneumography. (See
WARNING Do not connect more than one patient to a monitor.
WARNING Do not connect more than one monitor to a patient.
WARNING During defibrillation, keep discharge paddles away from the monitor
ECG lead wires, electrodes, any other monitor sensors, and other conductive
parts in contact with the patient.
WARNING Do not operate this product in the presence of flammable
anaesthetics or other flammable substances in combination with air or
oxygen-enriched environments. Failure to observe this warning can result in an
explosion.
WARNING Do not use the monitor in a Magnetic Resonance Imaging (MRI)
suite or a hyperbaric chamber. Such use can cause fire or explosion resulting in
patient injury and monitor damage.
WARNING Do not operate this monitor near equipment that emits strong
electromagnetic or radio-frequency signals. Electronic equipment of this type can
cause electrical interference with monitor operation, which can distort the ECG
signal and prevent accurate rhythm analysis.
