When is volume assist/control (V-A/C) indicated for use in ventilator management?

Volume assist/control (V-A/C) is indicated for use in ventilator management primarily when ensuring consistent minute ventilation is critical. This mode of ventilation delivers a predetermined tidal volume with each breath, whether the breath is initiated by the patient or the ventilator itself. This is particularly beneficial in situations where the patient's ability to maintain adequate ventilation may be compromised, such as in cases of respiratory failure or during sedation.

By guaranteeing a consistent minute ventilation, clinicians can effectively manage the patient’s carbon dioxide levels and optimize oxygenation, especially during transport or in high-stress environments where stability is paramount. This mode is not appropriate for fully conscious and cooperative patients since they might be able to breathe effectively on their own, and thus may not require the mechanical support offered by V-A/C.

It is essential to monitor vital signs continuously in any ventilated patient to assess their overall respiratory status and ensure that the ventilator settings are appropriate for their needs. Furthermore, if no further respiratory support is needed, the rationale for using V-A/C diminishes, as the patient could otherwise manage their ventilatory requirements independently.
