Arc Essentia® EEG System

Rugged 32‑Channel Monitoring for ICU, EMU & Routine Neurodiagnostics


Arc Essentia® is Cadwell’s work‑horse EEG platform—purpose‑built to record clean, reliable signals in the noisy realities of hospitals, epilepsy‑monitoring units, NICUs and busy outpatient clinics. Its water‑resistant, drop‑tested amplifier captures up to 32 channels at 2 kHz, while the colour‑coded Remote Input Headbox, single‑USB connectivity and Arc software automation keep hook‑ups fast and workflows smooth.

Key Features
  • Superior Signal Quality in Tough Environments: 32‑channel amplifier with seven active/reference pairs stores data at 250, 500, 1 000 or 2 000 Hz, preserving high‑frequency detail for seizure and ICU trend analysis. Fortified corners, sealed inputs and IP22 water resistance resist bumps, splashes and transport knocks without sacrificing performance. Continuous impedance and electrode‑continuity checks flash LED alerts the moment a contact loosens—protecting data integrity 24/7.
  • Fast, Error‑Free Patient Set‑Up: Remote Input Headbox mounts at the pillow: secure recessed connectors, large channel labels and 10‑20 colour coding speed clean hook‑ups and cut cable strain. A single USB cable powers the amplifier and streams data to any Arc workstation—ideal when seconds count in emergent seizures.
  • Ready for Any Care Area: Sized and rugged for ICU/NICU bedsides, ER crash carts, EMU suites or outpatient rooms; add respiratory belts for cEEG or mount the headbox on Cadwell carts and wall arms. Plug‑and‑play IP or USB HD cameras and the Arc USB Photic Stimulator integrate seamlessly for synchronized video and flash protocols. Patient Event Switch lets nurses, family or the patient mark clinical activity instantly for later review.
  • Arc Software Ecosystem: One‑click study launch, automated bad‑lead detection, CadReports™ Word‑based reporting and HL7/EMR export. Arc Sentinel™ central station shows live EEG, video and Synopsis® trends from multiple rooms; remote technologists can adjust studies without entering the unit. Optional Persyst® or Arc Synopsis® trending and spike detection accelerate interpretation and longitudinal analysis.
