•
Make frequent electrical and visual checks on cables and electrode wires.
•
Ensure the AC rating for the device is correct for the AC voltage at your installation site before using
the monitor. The AC rating is shown on the back of the instrument. If the rating is not correct, do not
use the monitor, and contact the Welch Allyn Technical Service Department for help.
•
Line isolation monitor transients may resemble actual cardiac waveforms and thus inhibit heart rate
alarms. Use care in placement of ECG electrodes and routing of cables to avoid interference and
noise.
•
Electrode polarization: the type of electrode used can affect the recovery time from overload,
especially defibrillation. Electrodes of dissimilar metals should not be used.
•
If the accuracy of any measurement is in question, check the patient's vital sign(s) by an alternate
method and then check the Atlas Monitor for proper functioning.
•
Extremity and cuff motion should be minimized during blood pressure determinations.
•
The pulse oximeter is calibrated to determine the percentage of arterial oxygen saturation of
functional hemoglobin. Significant levels of dysfunctional hemoglobins such as carboxyhemoglobin
or methemoglobin may affect the accuracy of the measurement.
•
Grounding reliability can only be achieved when equipment is connected to an equivalent receptacle
marked "Hospital Only" or "Hospital Grade".

Blood pressure measurements determined with this device are equivalent to those obtained by a
trained observer using the cuff/stethoscope auscultation method, within the limits prescribed by the
American National Standard, Electronic or automated sphygmomanometers (SP 10).
•
Blood Pressure measurements can be affected by the position of the patient, by the patient's
physiological condition, and other factors.
•
The Blood Pressure system and Temperature system may not meet specifications if operated or stored
at conditions outside the stated ranges, or subjected to excessive shock or dropping.
•
The Blood Pressure system is compliant with requirements of EN 1060-3:1995 Specification for
Noninvasive Sphygmomanometers.
•
The Atlas Monitor is designed with protective circuitry and current isolation that eliminates any risk
to the patient from possible software errors.
