What is one advantage of volume-control ventilation?

• A. It is easier to set up than pressure control
• B. It guarantees a specific volume delivery
• C. It lowers the peak inspiratory pressure automatically
• D. It requires less monitoring

Answer: (B)

One of the key advantages of volume-control ventilation is that it guarantees a specific volume delivery to the patient for each breath. This mode of ventilation is designed to deliver a preset tidal volume, regardless of the patient's lung compliance or resistance. This predictability is essential in critical care settings where ensuring adequate ventilation is paramount.

For patients with unstable lung mechanics, the ability to control the volume delivered helps to maintain sufficient ventilation and prevent hypoventilation or hyperventilation. This can be particularly beneficial in managing conditions where lung compliance is variable, such as in cases of ARDS (Acute Respiratory Distress Syndrome) or other restrictive lung diseases.

While other options may present certain benefits, the defining feature of volume-control ventilation is its ability to consistently deliver a set tidal volume, ensuring effective ventilation for the patient.
