10. RESPIRATION
Overview
Respiration via ECG Lead I or Lead II electrode makes the skin area of the chest enlarged, causing
changes in the resistance of skin. Through this it calculates respiration value per minutes and
performs the alarm function according to limit value.
The monitor can use ECG leads I or II for breath detection, regardless of the leads selected for
QRS processing. The measurement range for impedance breath monitoring is 0 to 155 breaths
per minute. The alarm setting range is 5 ~ 150 breaths per minute. In neonatal and pediatric
mode, the monitor can detect central apnea. You can monitor the heart rate, SpO2 using the
appropriate accessories, and display the relevant values in the Oxycardiorespirogram.
RESP precaution
Safety and efficacy of respiration measurement methods for apnea detection, especially apnea of
premature babies and apnea of infants, have not yet been established.
This device does not monitor obstructive apnea. Patients 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 patient'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 degraded. If pacemaker detection is enabled,
ESU interference may be detected as a pacemaker.
• Large amplitude pacemaker pulses ( > 100mV) may interfere with the monitor's breath
measurement or detection function.
