Which mode can be used to facilitate weaning from mechanical ventilation in addition to IMV?

• A. Pressure Control Ventilation (PCV)
• B. Pressure Support Ventilation (PSV)
• C. Adaptive Pressure Ventilation (PAV)
• D. Airway Pressure Release Ventilation (APRV)

Answer: (B)

Pressure Support Ventilation (PSV) is recognized for its ability to facilitate weaning from mechanical ventilation as it supports spontaneous breaths while allowing patients to initiate their own breaths and determine their tidal volumes. This mode significantly reduces the work of breathing by providing additional pressure during inspiration, which helps to strengthen respiratory muscles and enhances patient comfort. During weaning, it is crucial for the patient to maintain respiratory efforts and demonstrate the ability to breathe independently. PSV allows for a more gradual reduction of ventilatory support and encourages the patient to take an active role in their breathing efforts. This mode promotes synchrony between the ventilator and the patient's respiratory drive, making it an effective tool in the weaning process. While other modes such as Pressure Control Ventilation and Adaptive Pressure Ventilation can also be applied in certain scenarios, they may not provide the same level of spontaneous breathing support as PSV does, making them less optimal specifically for weaning. Airway Pressure Release Ventilation, while beneficial in other contexts, is typically used for more complex cases and may not directly facilitate the weaning process in the same way as PSV.
