A. Compliance and pressure are directly proportional; as compliance increases, pressure increases. B. Compliance and pressure are inversely proportional; as compliance decreases, pressure increases. C. Compliance and pressure are unrelated; pressure depends only on the set tidal volume. D. Compliance and pressure are inversely proportional; as compliance increases, pressure increases. Correct Answer: B Rationale: Compliance is defined as the change in volume divided by the change in pressure (C = ΔV/ΔP). When compliance decreases (lungs become stiffer, as in ARDS or pulmonary fibrosis), a higher pressure is required to deliver the same tidal volume. Conversely, when compliance increases (lungs become easier to inflate), less pressure is needed. This inverse relationship is fundamental to understanding ventilator-induced lung injury and the selection of pressure- versus volume-controlled modes. ________________________________________ Question 2 In volume-controlled ventilation, which variable is the independent variable that the ventilator maintains constant? A. Peak inspiratory pressure B. Tidal volume C. Airway resistance D. Patient effort Correct Answer: B Rationale: In volume-controlled ventilation, the ventilator delivers a set tidal volume regardless of changes in lung compliance or airway resistance. The tidal volume is the independent (control) variable, while the resulting airway pressure is the dependent variable that fluctuates with changes in respiratory system mechanics . This is why volume control guarantees minute ventilation but can produce dangerously high pressures if compliance deteriorates. ________________________________________ Question 3 During pressure-controlled ventilation, what happens to tidal volume if the patient's lung compliance suddenly decreases? A. Tidal volume increases proportionally. B. Tidal volume remains constant because pressure is constant. C. Tidal volume decreases. D. Tidal volume is unaffected by compliance changes. Correct Answer: C Rationale: In pressure-controlled ventilation, the ventilator maintains a constant inspiratory pressure (the independent variable), but the delivered tidal volume depends on the compliance and resistance of the respiratory system. If compliance decreases (lungs become stiffer), the same pressure will generate a smaller tidal volume, potentially leading to hypoventilation and hypercapnia. This is a critical limitation of pressure-targeted modes. ________________________________________
