Group comparisons of end-tidal gas targeting and global mean resting cerebral blood flow.

Healthy control subjects (N = 27) Sports-related concussion patients (N = 15) p-Value
Mean baseline PETCO2 ± SD (mmHg) 40.6 ± 4.1 40.7 ± 4.4 0.95
Mean change in PETCO2 during MPET CO2 targeting ± SD (mmHg) 4.0 ± 0.9 4.0 ± 1.1 0.98
Mean PETO2 over the period of the CO2 challenge ± SD (mmHg) 112.6 ± 3.2 112.6 ± 2.4 0.94
Global mean resting cerebral blood flow ± SD (mL/100 g/min) 41.0 ± 9.7 36.4 ± 7.0 0.13
