ACNS guidelines for CLTM actual exam questions and 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 10 K Ohms and balanced "Monitoring" (in LTME) does not imply Real time monitoring Noise reduction common mode rejection at least___ DB dynamic range of at least _____DB still looking for answeres
