AVAPS Explained: Indications, Settings, Physiology & Clinical Applications

AVAPS (Average Volume-Assured Pressure Support) is an advanced mode of noninvasive ventilation that combines the benefits of pressure support ventilation with a target tidal volume. By automatically adjusting inspiratory pressure support to achieve a desired tidal volume, AVAPS can help provide more consistent ventilation in patients with acute and chronic hypercapnic respiratory failure. In this video, we review the physiology of AVAPS, discuss how it differs from traditional BPAP, and explain common indications, settings, advantages, limitations, and troubleshooting strategies. We also cover practical applications in COPD exacerbations, obesity hypoventilation syndrome, neuromuscular disease, and other causes of ventilatory failure.
