What is the goal of providing pressure during inspiration in Pressure Support Ventilation?

The goal of providing pressure during inspiration in Pressure Support Ventilation (PSV) is to decrease the patient's overall work of breathing. PSV is a mode of mechanical ventilation designed to assist patients who are able to initiate their own breaths but require additional support during the inspiratory phase. By applying a preset level of pressure during inspiration, the ventilator reduces the respiratory muscle effort needed by the patient, allowing for easier and more comfortable breathing.

This support is particularly beneficial in cases where patients have compromised respiratory mechanics, fatigue, or disorders that make spontaneous ventilation challenging. As a result, the workload on the respiratory muscles is reduced, leading to enhanced patient comfort, decreased respiratory fatigue, and improved overall respiratory function.
