 Settings that can be adjusted in HFJV include 1) inspiratory time, 2) driving pressure, 3) frequency, 4) FiO2, and 5) humidity.Increases in FiO2, inspiratory time, and frequency improve oxygenation (by increasing "auto-PEEP" or pause pressure), while an increase in driving pressure and a decrease in frequency improve ventilation.The peak inspiratory pressure (PIP) window displays the average PIP.
