1) Controlled ventilation indeed allows the muscles of breathing to rest by taking over the work of breathing, which is beneficial in cases where the patient is unable to breathe effectively on their own.2) By adjusting the inspiratory to expiratory (I:E) ratio, controlled ventilation can indeed improve oxygenation, especially in conditions like ARDS (Acute Respiratory Distress Syndrome) where prolonged inspiratory times can help improve oxygenation.3) In patients who are spontaneously breathing, the use of paralytic agents (neuromuscular blocking agents) may be required to ensure that the patient's breathing efforts are fully synchronized with the ventilator or to eliminate spontaneous breathing efforts entirely, ensuring the full benefits of controlled ventilation.
