In volume mode ventilation, which of the following statements is true?

• A. Volume is variable; pressure is constant
• B. Volume is constant; pressure varies
• C. Both volume and pressure are variable
• D. Pressure remains constant while I-time varies

Answer: (B)

In volume mode ventilation, the hallmark is that the volume of air delivered to the patient is set to a specific constant amount per breath, ensuring that the patient receives a predetermined tidal volume regardless of the pressure required to deliver that volume. This is crucial for managing patients with different lung compliance and resistance, as the ventilator adjusts the pressure dynamically to achieve the set tidal volume. By setting a constant volume, clinicians can ensure that they provide adequate ventilation, especially in cases where lung function may be impaired. In this mode, the ventilator actively monitors and adjusts the pressure required to deliver the designated volume during each breath, allowing for variations in airway resistance or lung compliance without compromising the set volume. This aspect distinguishes volume mode ventilation from other modes where either the pressure is constant or both parameters can fluctuate. By understanding that volume is kept constant while pressure may vary, it becomes clear why this is the correct answer in the context of volume mode ventilation.
