NIBP100A and pulse plethysmography

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.

fNIRS High-Density Imaging Systems

fNIR Imaging Systems are stand-alone functional brain imaging solutions for continuous NIR spectroscopy (NIRS). They provide an in-lab cognitive function assessment and eliminate a great many of the drawbacks of a functional MRI. The subject can sit in front of a computer and take a test or perform mobile tasks. Imaging System – fNIR103S: Imager […]
