Infants with gas trapping are difficult to manage with conventional ventilation (CMV). HFJV has been used successfully in infants with severe gas trapping. The techniques used during HFJV in this situation are often described as a "low volume strategy". However, there is little published data to indicate optimal ventilator settings, both Jet and conventional, to achieve these aims.

During HFJV the following parameters must be set: CMV: Rate per min (R) Insp. time (Tl), Peak insp. p

The combination of congenital heart disease (CHD) and respiratory distress syndrome (RDS) can present a difficult scenario to manage with conventional mechanical ventilation (CMV). Our patient presented with poor right ventricular (RV) function, and refractory respiratory failure on CMV. High-frequency jet ventilation (HFJV) was used in order to improve ventilation at a similar or lower mean airway pressure (Paw) compared to CMV.

CASE: This patient was a 3.2kg male infant born at 33 W
