In volume control ventilation, tidal volume is the specific amount of air that is delivered to the patient with each breath. The defining characteristic of this mode of ventilation is that it ensures a set tidal volume is administered consistently with each mechanical breath, regardless of the patient's spontaneous attempts or respiratory needs.

When considering the nature of tidal volume in this context, it is designed to change based on the anticipated tidal volume that the clinician has determined is appropriate for the patient's condition and size. The tidal volume is typically adjusted according to the patient's needs, particularly taking into account factors such as lung compliance and resistance. This adaptability is crucial for ensuring effective ventilation and minimizing the risk of ventilator-induced lung injury.

As a fixed value in other modes of ventilation, tidal volume does not adjust in response to the physiological demands of the patient in volume control settings, which allows for precision in delivering the necessary volume of air but does not account for variations in respiratory effort and lung mechanics. This ensures that, while it is consistent, it remains tailored to the individual patient's characteristics. Thus, the tidal volume should indeed align with the professionally anticipated needs of the patient at any given time.
