According to 2016 ACNS guidelines, the recommended CMRR is at least what value?

• A. 90Hz
• B. 70dB
• C. 90dB
• D. 70Hz

Answer: (C)

The recommended Common Mode Rejection Ratio (CMRR) according to the 2016 American Clinical Neurophysiology Society (ACNS) guidelines is indeed at least 90 dB. CMRR is a critical parameter in EEG equipment as it indicates the ability of the system to reject noise and interference that is common to both input channels. A higher CMRR value means better performance in isolating the true brain signals from artifacts and noise, which is essential for accurate EEG readings and diagnoses. In clinical practice, having a CMRR of 90 dB ensures that the EEG recordings are reliable, enhancing the quality of the data collected during monitoring. This standard allows technologists to maintain integrity in their readings and ultimately leads to better patient outcomes. Lower values would indicate insufficient noise rejection capacity, which could compromise the quality and interpretability of EEG data.
