What are the advantages of transitional flow in high frequency jet ventilation (HFJV)?
Answer
Transitional flow in HFJV offers several advantages, particularly in reducing lung injury and improving secretion clearance.
Reduced Turbulence: Transitional flow minimizes turbulent flow, which can push dead space and secretions further into the lungs, leading to complications. Instead, it creates a smoother airflow that gently ventilates the lungs.
Piercing Dead Space: The flow design of HFJV allows fresh gas to pierce through dead space effectively, enhancing the removal of carbon dioxide (CO2) and preventing the build-up of secretions.
Passive Exhalation: HFJV’s reliance on passive exhalation facilitates smoother and more natural exhalation, reducing the work of breathing and minimizing stress on delicate lung tissues.
These features make HFJV an effective and gentle ventilation method, particularly suitable for patients with fragile lung conditions or significant secretions that need to be managed efficiently.

She started her career at Nemours Children's Health in Wilmington, Delaware, where she joined the CMO and Cardiac OR team and then became the PICU Clinical Lead. In her role as the PICU Lead, she enjoyed providing education not only to RTs but to nurses and physicians as well on mechanical ventilation and other Respiratory topics. Her love of educating and research landed her the current role of Clinical Instructor and Research Coordinator. Since in this role, Kelly has submitted over 30 abstracts to the AARC as well as multiple manuscripts. Kelly also enjoys volunteering her time presenting talks with ICON Academy and at AARC Congress and providing care during medical mission trips to Nigeria.
