790it 10 series upper arm blood pressure monitor

Heart rate was recorded using an ambulatory monitor (Mindware Technologies, Gahanna, OH), with a sampling rate of 500Hz. Data were collected for 5 minutes at each time point, and analyzed in 60-second segments. Values were the mean over each 5-minute period. Blood pressure was assessed with portable monitors (Omron 790IT 10+ Series Upper Arm Blood Pressure Monitor, Omron, Lake Forest, IL). Measures of pupil diameter were obtained at a rate of 30Hz (VIP^™-200 Variable Pupillometer, NeurOptics, Irvine, CA) and averaged over a 2-second period at each time point. Salivary cortisol was collected with Salivette® cotton wads (Sarstedt, Newton, NC). Cortisol levels were determined by the University of Chicago’s General Clinical Research Center (Salimetrics LLC, State College, PA, sensitivity = 0.003 μg/dL).
