Which settings need to be configured for PRVC operation?

• A. Target tidal volume and respiratory rate
• B. Target tidal volume and inspiratory time
• C. Ventilator mode and patient pressure
• D. Patient weight and height

Answer: (B)

In PRVC (Pressure Regulated Volume Control) operation, the primary settings that need to be configured include the target tidal volume and inspiratory time. The rationale behind this is that PRVC is designed to deliver a specific tidal volume while also accommodating the patient's lung mechanics. The ventilator adjusts the pressure delivered to achieve the targeted volume, ensuring adequate ventilation while reducing the risk of barotrauma. Setting the target tidal volume is essential as it defines the amount of air that is to be delivered with each breath to meet the patient's metabolic needs. The inspiratory time, or the duration of the breath delivery, can also significantly impact the delivery of the target volume within the constraints of pressure limits. Proper adjustment of both settings allows for effective patient-ventilator synchrony and optimal ventilation strategies tailored to the individual's needs. While other settings like ventilator mode and patient pressure are important for general operation, they do not directly specify the operational parameters for PRVC in the same way that tidal volume and inspiratory time do. Patient weight and height are typically used for calculating appropriate tidal volumes or adjusting settings in other modes but are not specific to PRVC operation.
