Changes in PETCO2 from baseline (BL) immediately prior to breathing on the respiratory impedance device (BL) to each minute of the dynamic cerebral autoregulation testing at PRE (a), 30 min of head-out water immersion (b), immediately post-immersion (c), and 45 min post-immersion (d) in thermoneutral (35 °C) and hot (39 °C) water during the dynamic cerebral autoregulation study. B = different from BL (P ≤ 0.05). n = 15
