Introduction Monitoring Resp (Optional)
9 - 2 TM80/TM70 Telemetry Monitor Operator’s Manual
9.1 Introduction
Impedance respiration is measured across the thorax. When the patient is breathing or
ventilated, the volume of air changes in the lungs, resulting in impedance changes
between the electrodes. Respiration rate (RR) is calculated from these impedance
changes, and a respiration waveform appears on the screen.
Resp monitoring is intended for adult and pediatric patients.
9.2 Resp Safety Information
WARNING
• The respiration measurement does not recognize the cause of no chest
movement. It only indicates an alarm if no breath is detected when a
pre-adjusted time has elapsed since the last detected breath. Therefore,
it cannot be used for diagnostic purpose.
• If operating under conditions according to the EMC Standard IEC 60601-
1-2 (Radiated Immunity 3V/m), field strengths above 3V/m may cause
erroneous measurements at various frequencies. Therefore, it is recom-
mended to avoid the use of electrically radiating equipment in close
proximity to the respiration measurement unit.
• The impedance respiration measurement may cause rate changes in
Minute Ventilation Rate Responsive Pacemakers. Set the pacemaker rate
responsive mode off or disable the impedance respiration measurement
on the monitor.
CAUTION
• Only use parts and accessories specified in this manual.
• Respiration monitoring is not for use on the patients who are very
active, as this will cause false alarms.
