Caution
To protect the Propaq CS monitor from damage during defibrillation, for accurate ECG information, and for
protection against noise and other interference, use only ECG electrodes and cables specified or supplied by Protocol
Systems (these cables have the required current-limiting resistors). Follow recommended application procedures.
• Impedance pneumography (RESP) is not recommended for use with high frequency ventilation.
• Since RESP is derived from the same leads as the ECG channel, the Propaq CS monitor determines
which signals are cardiovascular artifact and which signals are a result of respiratory effort. If the
breath rate is within five percent of the heart rate or a multiple or sub-multiple of the heart rate,
the monitor may ignore breaths and trigger an apnea alarm.
• When monitoring RESP it is highly recommended that you use SpO
2
monitoring as a backup
monitoring method.
• The Propaq CS monitor counts as “breaths” respiratory efforts that are larger than two times
background cardiovascular artifact.
• Even though the Propaq CS monitor contains fully isolated patient-connected circuitry, it has not
been specially designed for direct application on a patient’s heart.
• Use only with accessories provided or recommended in the Protocol Systems Products and
Accessories booklet.
• Severe artifact and interference (such as defibrillation interference) can cause the waveform to
move off the display for a few seconds before it is restored.
Prepare for ECG/RESP Monitoring
1. Inspect the ECG cable and replace it if it shows signs of wear, breakage, or fraying.
2. Select the appropriate patient mode. To change patient modes, from the Main Menu press
SETUP, MORE, CHANGE, then the desired patient mode (NEONATAL, PEDIATRIC, or ADULT) and then
YES.
3. Select electrode sites on the patient.
Choose flat areas; avoid fatty areas and major muscles.
4. Shave or clip hair from electrode sites, thoroughly clean skin, and lightly rub dry.
You may use soap and water, isopropyl alcohol or special skin preparation pads. To avoid allergic
reactions to electrodes, refer to the electrode manufacturer’s directions.
5. If you are using pre-gelled electrodes, make sure the electrode date is not expired and the gel
is intact and not dried out. For best results, use only silver/silver chloride electrode.
If you are using non-gelled electrodes, apply a 1/4 to 1/2 inch mound of gel over the electrode
contact area.
For best product performance and measurement accuracy, do not use stainless steel needle
electrodes, squeeze bulb electrodes, or electrodes with dissimilar metals. Do not use electrodes from
more than one manufacturer on the same patient.
