8 Monitoring Respiration Rate (Resp)
165
Interference
If operating under conditions according to the EMC Standard EN 60601-1-2 (Radiated Immunity 3V/
m), field strengths above 1V/m may cause erroneous measurements at various frequencies. Therefore
it is recommended to avoid the use of electrically radiating equipment in close proximity to the
respiration measurement unit.
Resp Accessories
To monitor respiration, use only the non-OR ECG accessories listed in the Resp section of the
accessories chapter. You cannot measure respiration if you are using an orange OR ECG cable set.
This is because of the higher internal impedance of the OR cable set, required for use if electrosurgery
is being performed.
Rate adaptive pacemakers
Implanted pacemakers which can adapt to the Minute Ventilation rate may occasionally react on the
Impedance measurement used by patient monitors for the determination of the Resp value and
execute pacing with the maximum programmed rate. Switching off the Resp measurement can prevent
this.
