Atria Electrocardiograph Operating Instructions
70-00082-01 A
NOTE:
Deviations from the technical specification ranges
listed can affect device performance.
The Atria is tested for IEC 60601-1-2 electromagnetic compatibility. The
failure criterion for the device is, “undetectable interference with the ECG
trace which could result in misdiagnosis.” While the device passes the
relevant standards, it may exhibit evidence of interference when subjected
to electrostatic discharges, high voltage transients or high voltage surges,
as defined in IEC 801-2, IEC 801-4 and IEC 801-5. The interference from a
single event will demonstrate as a sharp noise spike on the ECG trace. The
clinician will not confuse such a noise spike with the heart beat waveforms
and there is no hazard of misdiagnosis. In the unlikely situation the
equipment is placed in an environment where such interference events are
common, either the equipment or the interference source may be moved.
Battery pack
Under normal conditions, a fully charged battery pack provides adequate
power to print a minimum of 300 pages of data at paper speed of 25 mm/sec;
or a minimum of 55 minutes of continuous acquisition and printing.
A fully discharged battery pack will completely recharge in approximately
6 hours.
Heart rate detection
The Atria heart rate meter is specified to function in the range of 30 to 250
bpm with a tolerance of ±10% or ±5 bpm, whichever is greater. Question
marks (
???)
appear on the printout if the heart rate is out of the specified
range.
!
WARNING
False readings. The lead status check does not detect lead reversals.
Always ensure the correct lead placement is used for the lead
configuration selected.
!
WARNING
Patient injury or death. Do not use the Atria for unattended or continuous
patient monitoring. The Atria has no audible or visible alarms and change
to patient condition may not be immediately known.
The Atria is only intended for short-term ECG waveform acquisition.
