Kettering Mechanical Ventilation Practice Test 2026 – Complete Exam Prep

In assist/control mode of mechanical ventilation, one defining characteristic is the delivery of fixed tidal volumes with every initiated breath. This mode is designed to support patients who may be unable to breathe effectively on their own. When the ventilator detects an effort from the patient to breathe, it delivers a preset tidal volume, allowing both spontaneous and assisted breaths to be delivered with consistent volume. This helps ensure adequate ventilation and oxygenation, providing predictability and stability in respiratory support.

In this mode, every breath, whether initiated by the patient or triggered by the ventilator, results in the same predetermined volume of air being delivered. This characteristic is essential for maintaining effective gas exchange and reducing the work of breathing for patients who may have compromised respiratory function.
