Breathing 100% oxygen has been reported to decrease tidal volume (VT) in infants [1] and recent evidence published in the European Respiratory Journal suggest that transient less pronounced effects are also seen in preschool children [2]. It is unclear whether there is an age dependency beyond infancy in the response to 100% oxygen or whether it is limited to young children. Here we investigate the effects of 100% oxygen on breathing pattern across a spectrum of ages to identify the change in VT that occurs when subjects breathe 100% oxygen during a multiple breath nitrogen washout (MBNW) test. Changes in tidal breathing in response to 100% oxygen exposure are exhibited in subjects of all ages http://ow.ly/IZne30gIxLW

100% 氧气对呼吸模式的影响不仅限于幼儿

据报道，呼吸 100% 氧气会降低婴儿的潮气量 (VT) [1]，最近发表在《欧洲呼吸杂志》上的证据表明，学龄前儿童也有短暂的不太明显的影响 [2]。目前尚不清楚对 100% 氧气的反应是否存在超过婴儿期的年龄依赖性，或者是否仅限于幼儿。在这里，我们研究了 100% 氧气对不同年龄段呼吸模式的影响，以确定在多次呼吸氮气冲洗 (MBNW) 测试期间受试者呼吸 100% 氧气时发生的 VT 变化。所有年龄段的受试者都表现出响应 100% 氧气暴露的潮汐呼吸变化 http://ow.ly/IZne30gIxLW
