Exam Preview for 2251: High Frequency Jet Ventilation (HFJV): What,

High Frequency Jet Ventilation (HFJV): What, Why, When, and How

Please note: exam questions are subject to change.

1. How does the Bernoulli Effect impact breathing through a device like the LifePort? It slows down the gas flow in the lungs It reduces the efficiency of gas exchange It accelerates the gas into the lungs without filling up the airways It increases the volume of gas in the airways
2. Which type of High-Frequency Ventilation (HFV) system offers an adjustable I-Time, particularly beneficial for micropremies? High-Frequency Oscillatory Ventilation (HFOV) High-Frequency Jet Ventilation (HFJV) High-Frequency Percussive Ventilation (HFPV) High-Frequency Flow Interruption Ventilation (HFFIV)
3. In which scenarios is the Oscillator typically considered the ventilator of choice? During normal lung compliance When dealing with bronchospasm When patients are comfortable on conventional ventilation In cases of uniform non-compliance (e.g., Respiratory Distress Syndrome)
4. When might a patient be switched to High-Frequency Jet ventilation from conventional ventilation? Hemodynamically stable patients Cases involving excessive secretions and airleak syndromes Patients with uniform lung diseases and normal compliance None of the above
5. How is the adjustment of peak inspiratory pressure (PIP) different between conventional ventilation and high-frequency jet ventilation in micropremature infants? In CV, PIP should be set to control PaCO2 Maintain at 10 cmH20 once PEEP is optimized Maintain PIP 3-5 cm less than PEEP In HFJV, PIP should be set to control PaCO2
