CPAP, BPAP, AVAPS - Introduction to Non-Invasive Ventilation Strategies | Clinical Medicine

Non-invasive ventilation strategies are used both at home and in the hospital. In this video we discuss the three most common strategies - CPAP (continuous positive airway pressure), BPAP or BiPAP (bilevel positive airway pressure), and AVAPS (average volume assured pressure support). These strategies can be used for both Type 1 (low oxygen or hypoxemia) and Type 2 (high carbon dioxide or hypercapnia) Respiratory Failure. There are multiple different mask types, including nasal, nasal pillows, and full face mask.

We discuss how each of these strategies works from a physiologic standpoint. We then dive into the different settings and how to adjust/program them, including EPAP, IPAP, FiO2, Tidal Volume, Tmin, Tmax, Respiratory Rate, and more! Lastly, we dive into the different indications, such as obstructive sleep apnea (OSA), chronic obstructive pulmonary disease (COPD), heart failure (HF), neuromuscular diseases (NMD), obesity hypoventilation syndromes (OHS), and more. We finish out by discussing the contraindications, both absolute and relative.
