Chapter 10 Resp Monitoring
10.1 Resp(Respiration) Measurement
The monitor measures the respiration based on the thoracic impedance between the two electrodes. The changes
of such impedance caused by thoracic movements generate a respiratory waveform on the screen. The RR is
calculated from such a waveform.
Respiration measurement is intended for adult, pediatric and neonate patients.
10.2 Safety Information
If the respiratory detection level is set incorrectly in manual calculation mode the monitor may fail to
detect no breath. If the detection level is set too low the monitor may misinterpret a heartbeat as a
breath during apnea since it is easier to detect a heartbeat.
No breath alarm cannot recognize the cause of apnea and thus cannot be used for apnea diagnosis.
When the monitor works under conditions in compliance with IEC60601-1-2 (radiated immunity 3V/m),
the field strength over 3V/m may result in wrong measurements in all frequency ranges. Therefore, it is
advised not to use equipment of high EMC radiation near this monitor.
Impedance respiration measurement may cause a change in the pacing frequency of Minute Ventilation
Rate Responsive Pacemakers, in which case minute ventilation Response mode of the pacemaker or
impedance respiration measurement should be turned off.
When using a high-frequency Electrosurgical Unit (ESU), place the neutral electrode of the ESU close to
the surgical area and do not put the respiration lead cable between the surgical site and neutral
electrode to avoid burns.
Please check the packaging of the electrode is intact and is not out of date. Please use the electrode
immediately after unpacking. Do not use a dry electrode.
Respiration measurement is not intended for patients while they are active, otherwise it may lead to a
false alarm.
