9. Respiration
Overview
The monitor measures impedance respiration by sending a high frequency current between two
ECG electrodes placed on the animal's chest. At inspiration and exhalation, the electrical resistance
(impedance) between the electrodes changes with the contraction and expansion of the chest. You
can get respiratory waveforms and beats from these impedance changes.
The monitor can use ECG leads I or II for respiratory detection regardless of the lead selected for
QRS processing. The measuring range for impedance breath monitoring is 0 to 155 breaths per
minute. The alarm setting range is 5 to 150 breaths per minute.
RESP Precaution
Safety and efficacy of respiration measurement methods for apnea detection have not yet been
established.
⚫
This device does not monitor obstructive apnea. Animals in a breathing crisis should be
closely monitored.
⚫
Impedance breath monitoring should not be considered the only way to detect breathing
stops. Bionet recommends monitoring of additional parameters, such as EtCO2 and
SpO2, that indicate the animal's oxygen supply status.
⚫
If you use an ESU block or cable, the impedance breath monitor may not work and the
pacemaker detection performance may be impaired. If pacemaker detection is activated,
ESU interference may be detected as pacemaker extremes.
⚫
Large amplitude pacemaker pulses ( >100mV ) may interfere with the monitor's
respiration measurement or detection capabilities.
Animal Preparation
Skin preparation and lead placement must be properly and carefully monitored in impedance
breath monitoring. Doing so will produce reliable results. Follow the same recommendations as
for ECG monitoring.
