To Prepare The Ocs2 For Use; Current Setting - Integra OCS2 Manuel D'utilisation

To Prepare the OCS2 For Use

1. Sterilize the Ojemann Cortical Stimulator Probe (OCS2PND), product sold separately.
2. Insert the probe (OCS2PND) into the output receptacles ensuring jack is fully engaged
into the Ojemann Cortical Stimulator (OCS2).

Current Setting

1. Select the desired range using the Range switch.
2. Select the desired pulse rate and pulse duration settings using the Associated Control
knobs.
3. Turn the unit on by toggling the Power switch and ensure Battery Levels are
acceptable (it is recommended to replace the batteries if only 1 of the LED's is
illuminated).
4. Depress and hold the Output momentary switch in the Check Current position.
5. Adjust the selected current output knob (mA PEAK: LOW or FULL) for the desired
current output.
Warning
When stimulating, keep the Ojemann Cortical Stimulator Probe (OCS2PND) in firm
contact with the cortical tissue. Do not turn the output on until the probe is in firm contact
with tissue. Avoid incidental contact of the OCS2PND with the cortical surface.
Begin stimulation with the lowest current level and increase in small increments until the
desired physiological response is elicited. Stimulate at current levels that do not evoke
after discharges.
Integra recommends that current levels of 5mA are not exceeded when using a pulse
duration of 2 msec. Reduce the pulse duration at current levels above 5mA.
6. Optional: Insert a plug of a UL/IEC approved or passive device into the audio
receptacle located in back of the unit. Final system configuration should comply with EN
60601-1-1.
7. After the desired current setting is determined, place the probe tips in position on the
patient and set the Output switch to the Start position. The OCS2 is now delivering
stimulation current to the patient.
Notice
Use the LCD readout for precise output current values. The markings on the ma Peak
knobs are approximate (for reference only).
