Bronchopulmonary Dysplasia (BPD): A Conflict of Patient Management Strategies

Please note: exam questions are subject to change.

1. In high-frequency oscillatory ventilation (HFOV), what is one benefit of having more time to get gas in? Improved gas trapping Enhanced alveolar recruitment Reduced risk of barotrauma Decreased risk of hypoxemia
2. What potential issue may arise in patients with evolving bronchopulmonary dysplasia or chronic lung disease when exposed to shorter inspiratory times (I-times) with high-frequency jet ventilation (HFJV)? Decreased risk of hypercapnia Improved lung compliance Reduced risk of airleaks Elevated partial pressure of carbon dioxide (PCO2)
3. When using HFJV, what action is suggested to address gas trapping with insufficient expiratory time? Increase the jet rate Decrease the inspiratory time Lower the jet rate Increase the inspiratory time
4. According to Bland et al. (2000), what effect does mechanical ventilation with appropriate PEEP levels have on pulmonary edema in premature lungs? It exacerbates bronchospasm It avoids pulmonary edema It induces atelectasis It promotes smooth muscle growth in the small arteries
5. How do big tidal volumes affect alveolar growth during pulmonary structural growth? Significantly improves alveolar growth Have no effect on alveolar growth Disrupts alveolar growth, even at lower rates All of the above
