4) To record an ECG, one bipolar channel is used. Apply the cup electrodes
filled with conductive adhesive paste or disposable electrodes with a "button"
connector. In accordance with AASM manual single modified ECG lead II
and torso electrode placement are recommended (as shown in Fig. 46). Prior
to electrode placement degrease the patient's skin using an alcohol wipe.
Secure the positioned cup electrodes with medical tape or adhesive paste (in
case of excessively hairy areas). If adhesive paste is used, cover the elec-
trode with gauze pad square moistened with the paste and then push it tight-
ly to the electrode. Let the pad dry out. Plug the positioned electrode cables
to the electronic unit inputs in accordance with the montage. When
the testing is completed, remove the paste remains with warm water.

5) According to AASM thermal and pressure airflow sensors should be used to
monitor airflow. For identification of an apnea during a diagnostic study, use
a thermal airflow sensor. For identification of a hypopnea during a diagnostic
study, use a nasal pressure airflow sensor. If one of those sensors is not
functioning, it is recommended to apply other sensor to score apnea as well
as hypopnea. If two airflow sensors are used, position first an airflow thermis-
tor sensor in accordance with the related technical manuals.
6) If a piezoelectric snore sensor is used, ask the patient to simulate snore and
attach the sensor to the vibrating skin surface of the neck. Secure the sensor
with a medical tape (Fig. 47). The special preparation of the patient's skin is
not required. Connect the sensor to the electronic unit in accordance with
the exam montage.
