Abstract

Oxygen consumption (VO2) was measured during controlled and spontaneous ventilation with continuous positive airway pressure in newborn infants in whom chronic lung disease later developed. The oxygen cost of breathing (the difference in VO2 between spontaneous and controlled ventilation) was significantly higher in infants with chronic lung disease than in control infants (20.1% +/- 7.5% and 4.8% +/- 4.9% of VO2 during spontaneous ventilation (p < 0.05), respectively).

摘要

对后来发生慢性肺病的新生儿，在持续气道正压通气下进行控制通气和自主通气时测量了氧耗量（VO₂）。慢性肺病患儿的呼吸氧耗（自主通气与控制通气时VO₂的差值）显著高于对照婴儿（分别为自主通气时VO₂的20.1%±7.5%和4.8%±4.9%，p<0.05）。
