Abstract

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.

婴儿床内睡着的婴儿周围空气的二氧化碳浓度

室内空气质量对人类的健康至关重要，尤其是对婴儿而言。这项研究的重点是婴儿床内的空气质量。通过模拟装置的测量，研究了婴儿不同睡姿对婴儿床内空气质量的影响。婴儿的呼吸是通过一个带有呼吸装置的娃娃来模拟的:通过娃娃嘴唇上的一根管子，断断续续地向婴儿供应混合了二氧化碳的空气。对不同睡姿对婴儿床内二氧化碳浓度的影响进行了测量，并与睡眠时段的背景二氧化碳水平进行了比较。结果显示，根据婴儿的睡姿，二氧化碳浓度会增加(最多4倍)。

期刊介绍： This is a peer reviewed journal aimed at providing the latest information on research and application. Topics include: • New ideas concerned with the development or application of ventilation; • Validated case studies demonstrating the performance of ventilation strategies; • Information on needs and solutions for specific building types including: offices, dwellings, schools, hospitals, parking garages, urban buildings and recreational buildings etc; • Developments in numerical methods; • Measurement techniques; • Related issues in which the impact of ventilation plays an important role (e.g. the interaction of ventilation with air quality, health and comfort); • Energy issues related to ventilation (e.g. low energy systems, ventilation heating and cooling loss); • Driving forces (weather data, fan performance etc).
