Reproduced from Fig. 2 of Poublanc et al.8.
The extent and repeatability of an abrupt step change in lung SaO2 propagated to the middle cerebral artery. The gas challenge PO2 alternated between 40 and 95 mmHg; TR of 200 ms; time constants for reoxygenation for challenges 1–3 are 1.21 s, 1.67 s and 2.10 s, respectively.
