Which patient group would NOT typically benefit from proportional assist ventilation?

• A. Patients who can generate strong inspiratory efforts
• B. Patients with high compliance issues
• C. Patients with NM weakness who cannot generate a strong inspiratory effort
• D. Patients requiring minimal assistance

Answer: (C)

Proportional assist ventilation (PAV) is a mode of mechanical ventilation designed to support patients by providing assistance that is proportional to their own inspiratory efforts. It is particularly beneficial for patients who can initiate breaths but may require varying levels of support based on their strength and respiratory needs. Patients in situations where they can generate strong inspiratory efforts do well with PAV because the ventilator adjusts the level of assistance they receive based on their ability to breathe on their own. Those with conditions affecting lung compliance may present challenges, but they can still benefit from proportional assistance as long as they can initiate breaths. In contrast, patients with neuromuscular weakness who cannot generate significant inspiratory effort do not benefit from PAV because the mode relies on the patient's ability to trigger the ventilator and engage in the breathing process. If they are unable to initiate breaths effectively, the proportional assist feature becomes ineffective, leaving them without sufficient ventilation support. This group, therefore, is not suited for PAV as it does not provide the necessary assistance they require to facilitate adequate ventilation. Patients requiring minimal assistance might only need supportive ventilation that offers a lower level of assistance, which could also lead to challenges if they are unable to initiate breaths. However, the key point is
