Abstract The performances of two triggering systems using a single neonatal ventilator type (SLE) were compared. Eight infants, gestational age 27-30 wk, were each recorded during two 1-h periods of patient-triggered ventilation (PTVs), one with airway pressure and one with airflow triggering. The airflow trigger had a shorter trigger delay (p < 0.02), higher sensitivity (p < 0.02) and lower asynchrony rate (p < 0.02). CONCLUSION: In immature infants with mild respiratory distress syndrome using the SLE ventilator with inflation times of 0.3 to 0.36 sec, airflow triggering is more appropriate than airway pressure triggering.
