What distinguishes Volume Support (VS) from other forms of ventilation, such as PRVC?

• A. VS is solely controlled by the ventilator
• B. VS is only effective for spontaneous breaths
• C. VS does not require a back-up rate
• D. VS cannot be cycled by flow

Answer: (B)

Volume Support (VS) is specifically designed to assist spontaneous breathing efforts by delivering a preset tidal volume in response to the patient's inspiratory efforts. This mode provides a guaranteed volume of air for each breath the patient initiates, making it particularly effective for patients who are able to breathe on their own but may need additional support to ensure they receive adequate ventilation. The distinction lies primarily in the fact that VS adapts to the patient's efforts, meaning that if the patient takes a spontaneous breath, the ventilator will automatically adjust to provide support based on that effort. This contrasts with other modes like PRVC (Pressure Regulated Volume Control), which may not solely rely on the patient's own initiated breaths and can apply pressure control parameters to ensure set volume delivery. In this context, the effectiveness of VS for spontaneous breaths is what sets it apart from other forms of ventilation that may not be specifically designed for or limited to spontaneous efforts. Thus, its primary function is rooted in the support of patient-driven breathing, making it particularly useful in scenarios where patients are transitioning from full ventilatory support to independent breathing.
