Study Arms (2)

nasal high flow therapy

ACTIVE COMPARATOR

In this group, patients have undergone rehabilitation under the nasal high flow therapy (FiO2 100%, oxygen flow from 30 to 60 L/min) during four weeks.

Device: nasal high flow therapy

oxygen therapy

NO INTERVENTION

In this group, patients have undergone rehabilitation under the oxygen therapy via a nasal canula (6 L/min) during four weeks.

Interventions

The nasal high flow therapy has enabled high flow oxygen to be derived through nasal cannula. This mode not only allows constant FiO2 during peak inspiratory flow but also confers benefits including a low level of continuous positive airway pressure with increased end-expiratory lung volume and reduced work of breathing, partly through intrinsic positive end-expiration pressure compensation and dead space washout. The inspired gases are warmed and humidified, improving comfort and possibly reducing airway inflammation, leading to improved drainage of respiratory secretions.
