Introduction Monitoring Respiration (Resp) (Optional)
8 - 2 TM80 Telemetry Monitor Operator’s Manual
8.1 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.
8.2 Resp Safety Information
WARNING
• If you do not set the detection level for the respiration correctly in man-
ual detection mode, it may not be possible for the TM80 to detect apnea.
If you set the detection level too low, the TM80 is more likely to detect
cardiac activity, and to falsely interpret cardiac activity as respiratory
activity in the case of apnea.
• 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.
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.
