  • The inspiratory trigger was considered appropriate for a trigger time delay (Δt) of ≤100 ms and trigger pressure (ΔP) of ≤ -1.0 cmH2O, acceptable for a Δt of 100–150 ms and ΔP of -1.5–0 cmH2O or a Δt of 0–150 ms and ΔP of -1.5– -1.0 cmH2O, and inappropriate if the ventilator did not detect the inspiratory effort or in the case of autotriggering. The coping of the ventilator with leaks was ranked as follows: 1) relatively insensitive to a leak (no triggering or autotriggering for a leak of ≥40 L·min−1); 2) moderately sensitive to a leak (no triggering or autotriggering for a leak of 10–40 L·min−1); and 3) very sensitive to a leak (no triggering or autotriggering for a leak of ≤10 L·min−1). PSV: pressure-support ventilation; ACV: assisted controlled ventilation; PEEP: positive end-expiratory pressure; ZEEP: zero end-expiratory pressure; NCM: no compatible mode. #: flow trigger; : simple circuit; +: double-circuit pressure trigger.
