Current Concepts in Pediatric Critical Care-9: Nonconventional Ventilator Modes in PARDS

Video Transcription

Video Summary

The video discusses nonconventional ventilator modes in pediatric ARDS, including airway pressure release ventilation (APRV), high-frequency oscillatory ventilation (HFOV), high-frequency percussive ventilation (HFPV), and high-frequency jet ventilation. APRV is a mode that aims to sustain alveolar recruitment with a prolonged P-high and spontaneous respirations. It may improve oxygenation and ventilator perfusion matching. HFOV delivers a constant mean airway pressure with small tidal volumes and may improve oxygenation and ventilation. HFPV combines pressure control elements with high-frequency elements to improve CO2 clearance and clear secretions. The high-frequency jet ventilation mode delivers short bursts of inspiratory gas and may be used as an adjunct to bronchoscopy or in patients with pneumothorax, obstruction, or secretion clearance needs. The video also discusses the limitations and potential benefits of each mode. Overall, these nonconventional modes require higher mean airway pressures and may have specific indications for use in pediatric ARDS. The evidence supporting their use varies, and more research is needed to determine their efficacy and optimal application.
