What is a notable advantage of using Volume Support (VS)?

• A. The ventilator guarantees a set ventilatory rate
• B. The tidal volume is guaranteed over several breaths
• C. It offers complete control to the ventilator
• D. There is zero patient effort required

Answer: (B)

The notable advantage of using Volume Support (VS) is that the tidal volume is guaranteed over several breaths. In Volume Support mode, the ventilator provides assistance by delivering a preset tidal volume for each breath that the patient initiates or for breaths that are not spontaneously initiated. This ensures that the patient receives a consistent and adequate volume of air with each breath while allowing for some degree of patient-initiated breaths, thereby promoting effective ventilation. This capability makes Volume Support particularly useful for patients who are able to initiate breaths but may have compromised lung function, as it facilitates adequate ventilation while also accommodating the patient's own breathing effort. The ventilator closely monitors the patient's respiratory efforts to ensure that the target tidal volume is achieved, which can help improve carbon dioxide elimination and overall oxygenation. In contrast, the other options propose features that do not accurately represent the characteristics of Volume Support. For example, while it may offer some control, it does not guarantee a set ventilatory rate or require zero patient effort, as the patient can still breathe spontaneously and initiate their own breaths within the parameters set by the ventilator.
