Under the right clavicle. On the 7th left rib. Connection to the Nox A1: The EKG cable must be plugged into the bipolar EKG channel. 10 Patient hook-up • Place the PLM cables Equipment needed: PLM snap-on lead wire PLM snap-on lead wire 4 disposable adhesive electrodes Grey (PN 7073438) Black (PN 7073439) (PN 631526) Electrode site: Scrub the patient’s skin with NuPrep before placing the adhesive electrodes. Electrodes must be placed on the tibialis anterior muscle. If needed, secure the electrodes with tape and/or a Surgilast net. Connection to the Nox A1: Connect the black cable (left leg) to the LM1 bipolar input and the grey cable (right leg) to the LM2 bipolar input. 11 Patient hook-up • Place the chin EMG electrodes Equipment needed: 3 disposable adhesive electrodes (PN 7073775) Electrode site: Scrub the patient’s skin with NuPrep before placing the adhesive electrodes. F - On the midline and 1 cm above the inferior border of the mandible. 1 - 2 cm below the inferior border of the mandible and 2 cm right of the midline. 2 - 2 cm below the inferior border of the mandible and 2 cm left of the midline. Connection to the Nox A1: Connect corresponding electrodes to the inputs F, 1 and 2. 12 Patient hook-up • Place the EEG head cable Before attaching the electrodes, it is important to properly position the ground reference of the EEG head cable. 1 - Choose a snap-on electrode and place 3 - Connect the 2 EEG lead cables as the EEG head cable as shown below: shown below: 2 - Scrub the patient’s forehead with 4 - Pre-position the cups on the head. NuPrep and attach the electrode to the forehead by gently pressing on the white ring of the electrode. 13 Patient hook-up • Place the electrodes (10/20 system) E1 and E2 are respectively 1 cm below the left eye and 1 cm above the right eye. O1 and O2 are 3 cm below the occipital protuberance and 3 cm from the midline. C3 and C4 are on the pre-auricular points axis and 7 cm from the midline. M1 and M2 are respectively on the left and the right mastoids behind the ear. F3 and F4 are 1 cm before the hair line and 4 cm from the midline. 14 Patient hook-up • Attach the EEG electrodes Equipment needed: NuPrep abrasive gel 1 - Scrub the different electrode sites with NuPrep and a cotton bud. (PN 7073511) Remove excess gel with gauze. Ten20 conductive paste 2 - Fill the cups with Ten20 conductive paste and place them (PN 7073512) on the correct spots. EC2 electrode cream 3 - Place a small amount of EC2 cream on a piece of gauze. (PN 7073513) Place the gauze over the cup and onto the patient’s scalp so the cup stays in place.
