What are the typical settings adjusted on a volume-cycled ventilator?

The typical settings adjusted on a volume-cycled ventilator include tidal volume, respiratory rate, and PEEP (Positive End-Expiratory Pressure). Tidal volume is the amount of air delivered to the patient with each breath, which is critical for ensuring adequate ventilation and oxygenation. The respiratory rate is the number of breaths delivered per minute; adjusting this helps manage the patient's overall ventilation and ensures that the patient receives enough breaths to maintain effective gas exchange and avoid hypercapnia or hypoxemia. PEEP is used to enhance oxygenation by preventing the collapse of the alveoli at the end of expiration, which increases functional residual capacity and improves lung compliance.

The other options involve settings that may relate to different types of ventilators or modes of ventilation. For example, while FiO2 (fraction of inspired oxygen) is vital for maximizing oxygen delivery, it is not a primary adjustment for a volume-cycled ventilator specifically regarding its control over the delivered volume. Pressure support is more relevant in pressure-cycled ventilation. Similarly, while I:E ratio is important in certain ventilatory strategies, it doesn't specifically align with volume-cycled ventilators where volume delivery is the primary focus.
