NICO Smart Amplifier

The NICO Smart Amplifier is specifically designed to measure thoracic impedance for performing noninvasive cardiac output measurements. The amplifier terminates in two connectors for impedance (Z) and its derivative (dZ), and has a 3 m cable that connects directly to an AMI100D Amplifier Input Module. Use with EL500 series disposable electrodes and LEAD131 for a four-spot […]

NIRS and CNAP—Pairing great tools for great data Cerebral hemoglobin concentration (blood mass in the brain) is frequently measured in the prefrontal cortex, and systemic arterial blood pressure is known to be a variable factor based on the hemoglobin concentration. A leg pressure cuff was used to constrict and release blood flow to create a […]
