5. Respiration Monitoring 
Follow the preparation of “4.ECG Monitoring” to allow the respiration 
monitoring. 
 
This respiration monitoring is performed with impedance method. 
The ECG electrodes are also used for detecting the respiration. Each lead 
cable specifies the electrodes to detect the respiration. For 3-electrode and 5-
electrode (chest) lead cable, the electrodes to detect the respiration are fixed 
as follows. Even if lead method is switched, they are no changes. 
 
Lead Cable 
Color of Electrode 
3-electrode 
White (RA) and Red (LL) 
4-electrode 
White (RA) and Red (LL) 
5-electrode (Chest) 
White (RA) and Red (LL) 
 
WARNING 
Minute ventilation rate-adaptive implantable pacemakers can occasionally 
interact with certain cardiac monitoring and diagnostic equipment, causing 
the pacemakers to pace at their maximum programmed rate. The cardiac 
monitoring and diagnostic equipment may possibly send wrong 
information. 
If such event occurs, please disconnect the cardiac monitoring and 
diagnostic equipment, or follow the procedures described in the operation 
manual of the pacemaker. 
(For more details, contact FUKUDA DENSHI personnel, your institution’s 
professionals, or your pacemaker distributors.) 
Reference 
“Minute Ventilation Rate-Adaptive Pacemakers” 
FDA alerts health professionals that minute ventilation rate-adaptive 
implantable pacemakers can occasionally interact with certain cardiac 
monitoring and diagnostic equipment, causing pacemakers to pace at their 
maximum programmed rate. 
[October 14, 1998 (Letter: www .fda.gov/cdrh/safety.html) - FDA] 
 
CAUTION
 
  Even if the electrodes are attached on the proper positions for ECG 
monitoring, it may not be always the proper ones for respiration 
monitoring as well. 
  When a defibrillator is used during respiration monitoring, a large offset 
voltage will be placed on the ECG electrodes, which may cause 
interruption of monitoring for a few seconds.
