Abstract

The indoor air quality is important for the well-being of humans, especially in the case of young babies. This research focuses on the air qualityinside a crib with sleeping infants. The effects of different sleeping positions of the baby on the air quality within the crib were studied by measurements on modelled setup. The breathing of an infant was simulated by means of a baby doll which had a breathing device: a intermitted supply of air mixed with CO₂ through a tube in the lips of the baby doll. For different sleeping positions, the effects on the CO₂ concentration inside the baby bed were measured and compared with the background CO₂-level in the sleeping quarter. The results showed an increased CO₂ concentration (up to 4 times) depending on the sleeping position of the infant.

摘要

室内空气质量对人类的福祉很重要，尤其是对于年幼的婴儿。这项研究的重点是睡着婴儿的婴儿床内的空气质量。通过对模型设置的测量来研究婴儿不同睡姿对婴儿床内空气质量的影响。婴儿的呼吸是通过带有呼吸装置的娃娃来模拟的：通过娃娃嘴唇中的管子间歇地供应混合有 CO ₂的空气。对于不同的睡姿，测量对婴儿床内CO ₂浓度的影响，并与睡眠区的背景CO ₂水平进行比较。结果显示增加的 CO ₂ 浓度（最多 4 次）取决于婴儿的睡姿。
