What causes obesity hypoventilation syndrome?

Why does asthma cause hypoventilation?

In the early stages of acute asthma, hyperventilation may result in respiratory alkalosis. This is because obstructed lung units (slow compartment) are relatively less numerous than unobstructed lung units (fast compartment). Hyperventilation allows carbon dioxide removal via the fast compartment.
