ACNS GUIDELINES FOR CLTM EXAM 2024/2025 WITH 100% CORRECT ANSWERS Nichrome and platinum are... - Nonferrous metal, MRI compatible LTME digital equipment must record ( minimum) - 24 hrs of video and 32-64 channels of EEG LTME storage (minimum) - 30 gigabytes or 24 hrs of vid/EEG Intracerebral electrode impedance measurements...safe range - 10nA which is 1000 times less than reg 5-10Kohm for scalp What is the bare minimum number of channels in an LTME or primary EEG evaluation - 8 channels 12 or more are routinely used for accuracy in localization Electrodes, wires,amplifiers etc - Instrumental artifact creators. Ambulatory EEG artifact..create a reference - All common biological and mechanical arti should be produced by patient/tech at start or end of record. LTME Quality Assurance - Periodic check of live EEG should be preformed once a day. 16 channels EEG +1 eye and 1 EKG = - Minimum number of channels for presurgical localization. In-patient LTME - Qualified personal must observe the patient, record events and maintain recording integrity Name the group who creates the guidelines which classify seizures. - International League Against Epilepsy What does ACNS think is an acceptable instead of sphenoidals? - earlobe, anterior or sub temporal electrode recommended preformence specifications for amplifiers: LFF HFF input impedance - no higher than 1 hz with time constant of 0.16 a sec no lower than 70 Hz &monitor with min 1400 pixels
