Optimizing Flow-Controlled Ventilation: Impact of I:E Ratios and Oxygen Concentration in a Porcine Model of Total Airway Obstruction
FCV/EVA with 21% oxygen was feasible and maintained oxygenation and ventilation for 15 minutes. An I:E ratio of 1:1 was superior to 1:2. This approach may offer a viable alternative in a totally obstructed airway in resource-limited settings where higher oxygen concentrations are unavailable.
