Case Study 3: High Frequency Jet Ventilation (HFJV)
  • Baby Danielle is a 23 4/7-weeks’ gestation, female infant who is DOL 2 (post-menstrual age: 23 6/7 weeks). She is intubated and on mechanical ventilation since DOB with the current diagnosis of acute RDS status post (s/p) surfactant x 2 on DOB. She has been managed on SIMV volume targeted ventilation since birth and her current settings are FiO2 0.45, rate 50/minute, volume target 5 mL/kg, PEEP 5 cm H2O, Ti 0.35 seconds. Serial ABG results are showing a persistent CO2 retention ranging from 60–70 mmHg. Also, her current chest x-ray (CXR) shows evolving pulmonary interstitial emphysema (PIE). The decision is made to place Danielle on high frequency jet ventilation (HFJV).
