NCT05190458

Brief Summary

High velocity nasal insufflation (HVNI), a form of HFNC that utilizes a small bore nasal cannula to generate higher velocities of gas delivery than HFNC which uses large bore cannula, has the ability to accomplish complete purge of extra thoracic dead space at flow rates of 35 litres/min and may be able to provide ventilatory support in patients with respiratory failure in addition to oxygenation support in patients with overlap syndrome. This study aims to evaluate the effectiveness of HVNI compared to NIMV in management of respiratory failure in patients with obesity hypoventilation syndrome and overlap syndrome.

Interventions

High velocity nasal insufflation (HVNI), a form of HFNC that utilizes a small bore nasal cannula to generate higher velocities of gas delivery than HFNC which uses large bore cannula, has the ability to accomplish complete purge of extra thoracic dead space at flow rates of 35 litres/min and may be able to provide ventilatory support in patients with respiratory failure in addition to oxygenation support in patients with overlap syndrome.

High Velocity Nasal Insufflation (group B)

Noninvasive ventilation (NIV) refers to the administration of ventilatory support without using an invasive artificial airway (endotracheal tube or tracheostomy tube).
