Chapter 9 Monitoring RESP
9.1 Overview
The monitor measures respiration from the amount of thoracic impedance between two ECG
electrodes. The change of impedance between the two electrodes, (due to the thoracic movement),
produces a respiratory waveform on the screen.
9.2 RESP Safety Information
1
If you do not set the detection level for the respiration correctly in manual detection
mode, it may not be possible for the monitor to detect apnea. If you set the detection
level too low, the monitor is more likely to detect cardiac activity, and to falsely
interpret cardiac activity as respiratory activity in the case of apnea.
2
The respiration measurement does not recognize obstructive and mixed apneas - it
only indicates an alarm when a pre-adjusted time has elapsed since the last detected
breath.
3
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.
4
Cardiogenic artifact in impedance respiration monitoring may make it difficult to detect
breaths or may otherwise be counted as breaths. In some instances, the breath rate
may also correspond to the heart rate making it difficult to determine if the signal is
due to breathing or the cardiac cycle. Do not rely on RESP monitoring as the sole
method for detecting cessation of breathing. Follow hospital guidelines and best
clinical practices for apnea detection including monitoring additional parameters that
indicate the patient's oxygenation status, such as etCO
NOTE:
The RESP monitoring is not recommended to be used on patients who are very active, as
this can cause false alarms.
