To Apply the Chest and abdomen effort, Snore, Body Position Sensor
Chest and abdomen effort through the four button cables connect to the body chest and
abdominal electrode. Before sticking the electrode to the patient, skin should be cleaned by 95%
medical alcohol to erase skin oils for a good contact. The connection of the electrode is in Figure

swapped each other. To obtain the accurate data, BMC suggest using single use ECG electrode.
