Non-invasive ventilation in obstructive sleep apnoea/obesity hypoventilation syndrome: Experience from an Indian tertiary care respiratory centre

Key Points

• To evaluate the effectiveness of non-invasive ventilation (NIV) therapy in patients with obesity hypoventilation syndrome (OHS).
• Patients with OHS and acute on chronic hypercapnic failure were treated with NIV therapy.
• Exercise tolerance, weight loss, symptom burden, and blood gas parameters were measured pre- and post-treatment.
• All patients responded well to NIV therapy.
• Significant improvement in exercise tolerance was observed.
• Patients experienced weight loss and decreased symptom burden after treatment.
• Blood gas parameters showed notable improvement following NIV therapy.
