Patient triggered ventilation was assessed in 14 neonates (gestational age 24-40 weeks). Inspiratory changes in airflow, monitored by a pneumotachograph, were used to trigger the ventilator and this was not associated with complications. Patient triggered ventilation was maintained for up to eight hours (mean duration five hours). In 13 of 14 infants oxygenation improved and this was associated in most with an increase in rate of delivered positive pressure inflations and inflating volumes. A greater improvement in oxygenation was shown when trigger mode was used during the recovery phase of respiratory distress syndrome. Only one infant, who made very little respiratory effort, failed to improve. We conclude that patient triggered ventilation may be used as an effective form of neonatal ventilation.
对14名新生儿(胎龄24 - 40周)进行了患者触发通气评估。通过呼吸流速仪监测气流的吸气变化,以此触发呼吸机,且未出现相关并发症。患者触发通气维持了长达8小时(平均时长5小时)。14名婴儿中有13名的氧合状况得到改善,多数情况是与输送的正压通气频率和通气量增加有关。在呼吸窘迫综合征的恢复阶段使用触发模式时,氧合改善更为明显。只有一名呼吸努力极少的婴儿未出现改善。我们得出结论,患者触发通气可作为新生儿通气的一种有效形式。
