During pressure-targeted modes of ventilatory support, the volume delivered depends on which of the following?
1) Set pressure limit
2) Patient lung mechanics
3) Patient effort

Question

Quizplus · Accepted Answer

In pressure-targeted modes of ventilatory support, the volume of air delivered to the patient depends on the set pressure limit (which determines the maximum pressure provided by the ventilator), the patient's lung mechanics (such as compliance and resistance, which affect how the lungs expand and contract under pressure), and the patient's effort (which can influence the overall volume inhaled by affecting the initial lung volume and the pressure gradient). Thus, all three factors play a role in determining the delivered volume.
