Impedance respiration
WARNING
— DEFIBRILLATOR PRECAUTIONS — Patient signal inputs
labeled with the CF and BF symbols with paddles are
protected against damage resulting from defibrillation
voltages. To ensure proper defibrillator protection, use only
the recommended cables and leadwires.
WARNING
— ELECTRODE CONFIGURATION — Impedance respiration
monitoring is not reliable when ECG electrodes are placed
anywhere but on the chest.
WARNING
— ELECTRODES — Whenever patient defibrillation is
a possibility, use non-polarizing (silver/silver chloride
construction) electrodes for ECG monitoring. Polarizing
electrodes (stainless steel or silver constructed) may cause
the electrodes to retain a residual charge after defibrillation. A
residual charge will block acquisition of the ECG signal.
WARNING
— PDM and TRAM — If the Cardiac Artifact Alarm is turned
off, apnea events may not be detected.
Respiration cautions
CAUTION
The impedance respiration measurement may cause rate
changes in Minute Ventilation Rate Responsive Pacemakers.
Set the pacemaker rate responsive mode off (PDM and TRAM
only) or turn off the impedance respiration measurement on
the monitor.
Respiration measurement limitations
●
PSM: Impedance respiration is intended for patients over three years old.
●
Electrical devices, such as electrosurgery units and infrared heaters, that emit
electromagnetic disturbance, may cause artifacts or disable the respiration
measurement completely.
●
Movement artifacts, shivering, and interference from the heart may interfere with
the respiration measurement.
Respiration points to note
●
Connect only one impedance respiration module to the monitor simultaneously.
●
Do not place electrodes on obvious layers of fat, or major muscles.
●
Make sure the electrode gel is moist.
●
Make sure electrodes have good skin contact.
●
Depending on the respiration module used, not all respiration measurements and
settings are available to view or change.
●
Since respiration monitoring is so closely linked with ECG monitoring, patient
preparation and electrode placement are important.
●
Intermittent mechanical ventilation: During spontaneous breathing the ventilator
may at times support the patient’s ventilation with an extra inspiration. If these
ventilator inspirations are substantially larger than the spontaneous breaths, the
respiration calculation may mistakenly count only the inspirations and expirations
produced by the ventilator.
