In which modes can volume control (VC) be utilized?

• A. Only in controlled modes
• B. AC, IMV, and SIMV modes
• C. Only during spontaneous ventilation
• D. In all modes of ventilation

Answer: (B)

Volume control (VC) can be utilized in specific ventilatory modes that allow for predetermined tidal volumes to be delivered with each breath. In Assist-Control (AC), Intermittent Mandatory Ventilation (IMV), and Synchronized Intermittent Mandatory Ventilation (SIMV) modes, the clinician can set a specific volume of air to be delivered with each breath. This allows for consistent ventilation and can help ensure adequate oxygenation and carbon dioxide removal. In AC mode, the ventilator will deliver a set volume each time a breath is triggered, either by the patient or set by the machine. IMV allows for spontaneous breaths in between mechanically delivered breaths, providing a blend of controlled and spontaneous ventilation while still ensuring that each mandatory breath meets the volume target. SIMV combines the principles of AC and spontaneous breathing, allowing for a set number of mandatory breaths at a specified volume while also permitting the patient to take additional breaths, ideally at his or her own volume. While volume control can be set on various ventilator modes, not all modes are suited for incorporating volume-controlled strategies. For example, in spontaneous ventilation modes, the tidal volume is usually determined by the patient's own respiratory effort, not preset by the ventilator. Hence, the versatility of volume control
