Position 4
In this position, the respiration measurement is influenced by the impedance variation of the
abdomen, so the cardiac pulse wave included in the respiration wave is reduced. Note that the
waveform is inverted in phase compared with the chest movement (the waveform goes down
during inspiration). It is difficult to measure the ECG at the same time.

Attaching Electrodes to the Patient and Connecting the Electrode Leads to
Disposable Electrodes
Prepare the Patient Skin
Shave off excessive body hair.
To reduce skin impedance, clean the electrode site with cream or with a cotton pad moistened
with alcohol. Thoroughly dry the skin with a clean cotton pad.
NOTE
• For a patient with frequent body movement, rub the sites with skinPure skin
preparation gel. However, do not use skinPure skin preparation gel on sensitive skin.
• Do not place electrodes on a wound or on an inflamed, wrinkled or uneven skin
surface.
Attaching Electrodes to the Patient
CAUTION
Do not reuse disposable parts and accessories.
NOTE
• To maintain good contact between the electrode and skin, check that the paste of the
disposable electrode is not dry.
• When contact between the disposable electrode and skin becomes poor, replace
electrodes with new ones immediately. Otherwise, contact impedance between the skin
and the electrode increases and accurate ECG and respiration waveforms cannot be
obtained.
