REBEL Core Cast 148.0–Demystifying Non-Invasive Ventilation & HiFlow

Non-invasive respiratory support requires balancing patient comfort with physiological needs to avoid intubation. CPAP provides continuous pressure, while BiPAP utilizes distinct inspiratory (IPAP) and expiratory (EPAP) pressures to offload respiratory muscles and improve tidal volume. High-flow nasal cannula offers an alternative, leveraging heated and humidified gas to meet high inspiratory flow demands, improve functional residual capacity, and facilitate CO2 washout through the reduction of anatomical dead space. While these modalities effectively bridge patients during respiratory failure, they carry risks, including airway insecurity and the potential need for sedation to manage patient distress. Clinical application relies on matching the device to the underlying etiology—such as hypercapnia or hypoxemia—while remaining mindful that these supportive therapies are not substitutes for treating the primary disease process.
