Predictive value of tidal volume and peak inspiratory pressure in normal frequency jet ventilation.

ABSTRACT: Normal frequency jet ventilation (NFJV) is commonly used during rigid bronchoscopy; however, airway opening does not reliably measure or predict tidal volume (V_T) or peak inspiratory pressure (PIP). This study aimed to investigate the comprehensive effects on V_T and PIP concerning key variables, including driving pressure (DP_pipeline), frequency (F_jet), needle inner diameter (ID_needle), and lung dynamic compliance (C_dyn). Three jet needles (N₁, N₂, and N₃) with different internal diameters (1.2-1.9 mm) were used to deliver jet ventilation via a rigid bronchoscope at DPs of 0.6-1.6 bar and frequencies of 10-60 min⁻¹. Airway pressure (Paw) was measured near the tracheal prominence of the simula
