From: Effect of airway acidosis and alkalosis on airway vascular smooth muscle responsiveness to albuterol

Challenges V̇ (L.min-1) EBC pH (units)
Quiet breathing 14.4 ± 4.2 6.39 ± 0.14
Eucapnic hyperventilation 35.5 ± 3.4* 6.31 ± 0.08
Hypocapnic hyperventilation 35.2 ± 3.3* 6.59 ± 0.15**
Hypercapnic hyperventilation 24.4 ± 2.9* 5.88 ± 0.14**
  1. V̇, ventilation.
  2. EBC, exhaled breath condensate.
  3. *p < 0.05 vs. quiet breathing.
