ESPIRATION
Overview
The monitor measures impedance respiration by passing a harmless high-frequency
current between two ECG electrodes on the patient's chest. Electrical resistance
(impedance) between the electrodes varies with the chest’s expansion and contraction
during inspiration and expiration. You can derive a respiration waveform and rate
from these impedance changes.
The monitor can use ECG leads I or II for breath detection regardless of the lead
selected for QRS processing. The measurement range for impedance respiration
monitoring is 0 to 155 breaths per minute. The range for alarm settings is 5 to 150
breaths per minute. In neonatal and pediatric mode, the monitor can detect central
apnea. Using the appropriate accessories, you can also monitor heart rate, SpO

, and
tpO
