In a volume cycle mode, what happens once the preset volume is delivered?

In a volume cycle mode, the ventilator is designed to deliver a predetermined tidal volume to the patient with each breath. Once the preset volume is achieved, the ventilator stops providing additional volume. This mode ensures that the set volume is consistently delivered to the patient regardless of changes in lung compliance or resistance. The concept is crucial in mechanical ventilation as it allows for precise control of the volume delivered to the patient, ensuring effective ventilation and preventing potential complications associated with under- or over-distension of the lungs.

The mechanism of pressure delivery is controlled tightly until the full volume is achieved, at which point the ventilator will terminate the breath. This method is effective for patients who require assurance that a specific volume is delivered with each breath, making it particularly beneficial in cases where maintaining adequate ventilation is critical.
