(A) Simultaneous measurements of arteriolar diameter and perivascular NO, normalized by baseline diameter and electrode current. Superfusion was changed from 5% O₂ to low O₂ at t = 4 min, then back to 5% O₂ at t = 17 min, following an IP injection of NaNO₂ at t = 7 min. (B) Correlation between the normalized perivascular NO and normalized diameter.
