Ineffective efforts and operation of apnea ventilation during pressure control continuous spontaneous ventilation (PC-CSV). Ineffective efforts and operation of apnea ventilation during pressure control continuous spontaneous ventilation (PC-CSV). Servo-i and Avea ventilators tested with and without proximal flow sensors. A = Apnea ventilation was activated, and no spontaneous recovery was seen. AR = Apnea ventilation was activated, and ventilator recovered triggering spontaneously. IE = Ineffective efforts occurred in >20% of simulated breaths. AR* = Apnea ventilation was activated only when leak decreased to that level. Ventilator recovered triggering spontaneously. IE* = Non-sustained ineffective efforts occurred only when leak decreased to that level. Apnea ventilation was not activated. LB = baseline leak; L1–L3 = leak levels 1–3. Taiga Itagaki et al.
