What is pressure augmentation (PAug) primarily used for?

• A. Delivering continuous positive airway pressure
• B. Providing pressure-limited ventilation with volume delivery targeted for every breath
• C. Increasing tidal volume only during exertion
• D. Monitoring respiratory rates

Answer: (B)

Pressure augmentation (PAug) is primarily used in the context of providing pressure-limited ventilation with a focus on achieving volume delivery targeted for every breath. This mode allows for the adjustment of airway pressure during mechanical ventilation, with the goal of delivering a set tidal volume while managing lung compliance and resistance. This is particularly useful for patients whose respiratory drive may be diminished or who require support in maintaining adequate ventilation. When PAug is utilized, the ventilator can sense the patient's effort to breathe, ensuring that the delivered tidal volume meets the targeted value even if the patient's own respiratory strength varies. This approach enhances the synchronization between the patient and the ventilator, effectively improving ventilation efficiency and patient comfort. Other options, such as continuous positive airway pressure or increasing tidal volume only during exertion, do not fully encapsulate the purpose and function of pressure augmentation, which is specifically designed to support controlled ventilation while allowing for patient-initiated breaths. Monitoring respiratory rates is a separate function that does not relate to the primary use of PAug in managing ventilation effectively.
