What does PVS stand for in terms of ventilation support?

• A. Primary ventilatory support
• B. Pressure ventilation support
• C. Partial ventilatory support
• D. Peak volume support

Answer: (C)

Partial ventilatory support (PVS) refers to a mode of ventilation where the ventilator assists a patient in breathing but still allows for the patient to initiate breaths on their own. This mode is particularly useful for patients who have some ability to breathe spontaneously but may require support to ensure adequate ventilation and oxygenation. In this context, PVS helps to bridge the gap between complete reliance on mechanical ventilation and fully spontaneous breathing. It can involve systems where the ventilator delivers pressure or volume in response to the patient's efforts, thereby accommodating their needs while promoting respiratory muscle conditioning and helping to prevent ventilator dependence. The other options, while plausible sounding abbreviations, do not accurately describe the specific mechanism and purpose of this support mode as effectively as partial ventilatory support does.
