Troubleshooting with Ventilator Graphics: Obstructive Physiology

Please note: exam questions are subject to change.

1. What is a primary issue in COPD obstructive physiology that differs from asthma? Increased mucus obstruction Inflammation Bronchoconstriction All of the above
2. Current challenges in mechanical ventilation interpretation of waveforms have identified the need to implement which of the following? A standardized nomenclature for patient-ventilator interactions A standardized approach for analyzing the waveforms A large population of clinicians who have been trained to use waveforms for diagnostic purposes All of the above
3. Performing a momentary end-inspiratory hold interrupts flow delivery, and gives us insight into ______________. Dynamic Hyperinflation Airway Resistance Static Compliance Mechanical power
4. What is the importance of understanding time constants when managing mechanically ventilated patients with obstructive lung physiology? It is not important Establishes a standard interval of time to re-assess patients after changes to vent settings Aids in optimizing alveolar ventilation and gas exchange Sounds philosophical
5. Slow emptying of lung units helps to guide the clinician toward changes in lung function, including: Increased resistance and compliance Decreased compliance Normal airway resistance Low airway resistance
