Exam Preview for 1271: High Frequency Oscillatory Ventilation (HFOV

High Frequency Oscillatory Ventilation (HFOV) and High Frequency Jet Ventilation (HFJV): Strategies for Success

Please note: exam questions are subject to change.

1. What is a key characteristic of High Frequency Oscillatory Ventilation (HFOV)? Passive exhalation Variable I:E ratio Conventional ventilator usage Relatively constant MAP
2. In what situations is recruitment or re-recruitment necessary in HFOV? Only when changing the ventilator settings Before suctioning After any disconnection Only during scheduled breaks
3. In assessing X-ray appearance for lung recruitment, which element is considered the LEAST important indicator? Rib count Diaphragm Heart size Lung fields
4. What is the potential consequence of employing high flow when using HFOV? Improved oxygenation Lower risk of barotrauma Turbulence and increased airway resistance Decreased airway resistance
5. In what scenario is High Frequency Oscillatory Ventilation (HFOV) typically indicated when conventional ventilation proves ineffective? Routine monitoring During patient transport After routine suctioning In cases of pulmonary hypoplasia
