Mechanical Ventilation: Lung Mechanics of Resistance and Compliance Measurement

Please note: exam questions are subject to change.

1. The RT finds a decrease in static compliance and suspects all, but which of the following? Pleural effusion Obstruction of ET tube Pneumothorax Adult respiratory distress syndrome
2. What is the normal airway resistance and static compliance for an intubated, mechanically ventilated patient? 0.6 to 2.4 cm H20/L sec and 70 to 100 ml/cm H20 0.6 to 2. 4 cm H20/L/sec and 60 to 80 ml/cm H20 1 cm H20/L/sec and 40 to 50 ml/cm H20 5 cm H20 /L/sec and 80 to 120 ml/cm H20
3. The RT notices an increase in peak airway pressure from 28 cm H20 to 50 cm H20, but no change in Pplat. What is the most likely cause for the change? Decreased Raw Increased lung Cs Increased Raw Decreased lung Cs
4. The RT may measure static compliance, dynamic compliance, and airway resistance on mechanically ventilated patients for all purposes, except which one of the following? To monitor a patient with adult respiratory distress syndrome To determine the level of sedation To evaluate an acute increase in peak inspiratory pressure To determine if the static compliance is decreasing
5. What are the two components into which inspiratory pressure is divided? Alveolar pressure and respiratory compliance Resistive and alveolar pressure Chest wall pressure and airflow None of the above
