AVAPS vs BPAP: Key Differences, Settings & Clinical Applications BPAP and AVAPS are two commonly used forms of noninvasive ventilation, but understanding how they differ and when each mode may be appropriate can be challenging. While BPAP delivers fixed pressure support through preset IPAP and EPAP settings, AVAPS adds a target tidal volume and automatically adjusts inspiratory pressure support to help maintain that goal. In this episode, we compare BPAP and AVAPS, review the physiology behind each mode, discuss practical settings, and explore common clinical applications. We also review the advantages, limitations, and troubleshooting strategies for both modalities and discuss how they are used in patients with COPD exacerbations, hypercapnic respiratory failure, obesity hypoventilation syndrome, neuromuscular disease, and other causes of ventilatory failure.
