Every year, 12 million emergency department patients fail to get the rapid EEG required to save lives.

Every year, 12 million emergency department patients fail to get the rapid brain function assessment of an EEG required to guide therapy and save lives. Only two percent of emergency departments have EEG and 68 percent can’t get one done in fewer than four hours.

Currently there are three key obstacles to recording EEG in Emergency Departments:

  1. There’s no EEG machine designed for Emergency Department usage. Current machines are too large, difficult to use, and don’t function well in the Emergency Department environment.
  2. There is a need for 24/7 specialized EEG technicians.
  3. There is a need for 24/7 specialists to interpret EEGs.

BioSignal’s microEEG® removes all of these obstacles.

microEEG is a wearable, wireless, and FDA approved EEG device that rapidly captures and transmits EEG data. The microEEG integrates with StatNet™ and EZEnet® for a fast EEG that takes five minutes to set up without the need for an EEG technician. The EEGs are automatically sent from the emergency department via our HIPAA compliant, cloud based EEG Interpretation Platform (EIP) to a neurologist for remote interpretation.

At A Glance:

  • 24/7/365 EEG

  • Setup in 5 minutes without the need for an EEG technician

  • Reduce patient care costs by 31%

  • Reduce rate of readmission within 30 days of discharge by 26%

  • Reduce hospitalization length of stay by 2 days


In a typical 200 bed hospital, 13 patients a day are at risk of being admitted to the hospital from the emergency department with an “Undifferentiated” or “Other” diagnosis. Of these, three are sent to an ICU bed. ICU beds are being taken up by patients who may not need them, and patients are kept in ICU beds longer than needed. BioSignal improves the outcomes for these patients.


Of all patients entering an emergency room, four to ten percent present with Altered Mental Status. Of these patients, 84 percent are admitted and 21 percent are sent to the ICU. We can reduce the ICU stay for an AMS patient from 11.55 days to 7.67 days.
