Interventions

They each had three cerebral oximetry devices (FORE-SIGHT ELITETM [CAS Medical Systems, Inc.

Branford, CT], INVOS 5100cTM [Medtronic, Minneapolis, MN, USA], and NIRO-TRS [Hamamatsu Photonics

Hamamatsu, Japan]) applied to the forehead. A circumferential pneumatic head cuff was positioned beneath the NIRS cerebral oximetry sensors. We measured rSO2, heart rate (HR), and blood pressure (BP)
