To date,the clinical use of functional near-infrared spectroscopy(nIRS)to detect cerebral ischemia has been largely limited to surgical settings,where motion artifacts are *** this study,we present novel techniques to address the challenges of using nIRS to monitor ambu-latory patients with kidney disease during approximately eight hours of hemodialysis(HD)*** with end-stage kidney disease who require HD are at higher risk for cognitive impairment and dementia than age-matched *** studies have suggested that HD-related declines in cerebral blood flow might explain some of the adverse outcomes of HD ***,there are currently no established paradigms for monitoring cerebral per-fusion in real-time during HD *** this study,we used nIRS to assess cerebral hemo-dynamic responses among 95 prevalent HD patients during two consecutive HD *** observed substantial signal attenuation in our predominantly Black patient cohort that required probe *** also observed consistent motion artifacts that we addressed by devel-oping a novel nIRS methodology,called the HD cerebral oxygen demand algorithm(HD-CODA),to identify episodes when cerebral oxygen demand might be outpacing supply during HD *** then examined the association between a summary measure of time spent in cerebral deoxygenation,derived using the HD-CODA,and hemodynamic and treatment-related *** found that this summary measure was associated with intradialytic mean arterial pressure,heart rate,and volume *** studies should use the HD-CODA to implement studies of real-time nIRS monitoring for incident dialysis patients,over longer time frames,and in other dialysis modalities.
