We do not recommend using the pulse transducer on the same hand as the NIBP100A transducer if you are performing pulse transit time measurements. The NIBP100A will have some influence on the PPG data because it applies a cyclic pressure (cycles every ~10-15 seconds) to the radial artery. During times of compression the pulse transit time will slow somewhat and the pulse signal will flatten out because the radial compression will act like a low-pass filter on the vasculature.
A work-around might be to use the NIBP100A and PPG on different hands.
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 […]
