What key settings are established when using volume control ventilation?

• A. Only tidal volume (VT)
• B. Minute ventilation and peep
• C. Tidal volume (VT) and flow rate (V̇)
• D. Respiratory rate (RR) and end-expiratory pressure

Answer: (C)

In volume control ventilation, the primary objective is to deliver a specific volume of air with each breath, which is determined by the tidal volume (VT) setting. Alongside VT, the flow rate (V̇) is also a crucial setting that influences how rapidly the set tidal volume is delivered to the patient. The flow rate affects the inspiratory time and can influence patient comfort and tidal volume delivery dynamics during the ventilatory cycle. Correctly setting both tidal volume and flow rate ensures that the volume of air delivered meets patient needs while also considering factors like compliance and resistance within the respiratory system. This can optimize ventilation efficiency and assist in maintaining adequate gas exchange. The other options focus on different combinations of settings, which do not capture the primary aspects of volume control ventilation as effectively as the combination of tidal volume and flow rate.
