Twenty premature infants ventilated for respiratory distress syndrome (RDS) were studied using a new computerised technique to determine spontaneous inspiratory and expiratory times. The technique is continuous and non-invasive. Infants were studied during intermittent positive pressure ventilation for periods of up to 45 minutes. Median birth weight and gestation were 1477 g and 30 weeks. The median number of breaths analysed for each baby was 925. The median (range) for spontaneous inspiratory time was 0.30 (0.26 to 0.34) seconds and for spontaneous expiratory time it was 0.46 (0.34 to 0.66) seconds. The spontaneous inspiratory and expiratory times were different from the ventilator settings.
采用一种新的计算机技术对20例因呼吸窘迫综合征(RDS)接受通气治疗的早产儿进行研究,以确定其自主吸气和呼气时间。该技术具有连续性且无创。在间歇性正压通气期间对婴儿进行长达45分钟的研究。出生体重中位数和胎龄分别为1477克和30周。每个婴儿分析的呼吸次数中位数为925次。自主吸气时间中位数(范围)为0.30(0.26至0.34)秒,自主呼气时间中位数为0.46(0.34至0.66)秒。自主吸气和呼气时间与呼吸机设置不同。
