How does Volume Support (VS) differ from Pressure Support Ventilation (PSV)?

• A. VS only supports controlled breaths
• B. In VS, the PS level is adjusted breath by breath
• C. PSV guarantees a minimum tidal volume
• D. VS does not allow patient-triggered breaths

Answer: (B)

Volume Support (VS) differs from Pressure Support Ventilation (PSV) primarily in how breaths are supported and how the system adapts to the patient's needs. In Volume Support, the pressure support level can be adjusted on a breath-by-breath basis to achieve a target tidal volume. This adaptability ensures that the patient receives sufficient ventilation based on their specific respiratory needs at any moment. If the patient's effort is low, the device will increase the pressure to deliver the desired tidal volume. Conversely, if the patient is breathing effectively and producing sufficient tidal volume, the pressure support may decrease. This dynamic adjustment is what sets Volume Support apart, making it particularly beneficial in providing adaptive ventilation tailored to the patient's changing respiratory status. In contrast, Pressure Support Ventilation provides a set level of pressure for each supported breath but does not inherently guarantee a specific tidal volume. Understanding this difference is essential for optimizing patient-ventilator interaction and ensuring effective ventilation strategies in clinical settings.
