Some Japanese bedding were assessed on the assumption of the effects of air trapping. The change of CO2 concentration in the airway of a mannequin placed on bedding was monitored using a CO2 analyzer during simulated breathing. To compare the level of CO2 dispersal among different items of bedding, CO2 half time (t1/2) values were used. The t1/2 values were calculated by measuring the time required for the expired percent CO2 to reach 1/2 the initial percent end-tidal PCO2. When the doll was placed face down on the bedding, all t1/2 values increased in comparison with those of supine position. With respect to present baby futon (hard mattress type), there may be a relatively low potential for rebreathing to occur, compared with soft futon. In every case, the t1/2 value was prolonged by the use of a towel spread on the futon. CO2 dispersal may depend not only on the softness of the futon, but on the combination of bottom sheet/towel and mattress. The potential of rebreathing increased in face down position among all bedding, and supine position was the best CO2 dispersal position.

在假定空气捕获效应的情况下，对一些日本床层进行了评估。在模拟呼吸过程中，使用二氧化碳分析仪监测放置在床上的人体模型气道内二氧化碳浓度的变化。为了比较不同垫层间CO2的扩散水平，采用CO2半时间（t1/2）值。t1/2值是通过测量过期CO2百分比达到初始潮汐末CO2百分比的1/2所需的时间来计算的。当娃娃面朝下放在床上时，所有t1/2值都比仰卧位时增加。就目前的婴儿蒲团（硬床垫类型）而言，与软蒲团相比，发生再呼吸的可能性相对较低。在每种情况下，t1/2值通过在蒲团上使用毛巾延长。二氧化碳的分散可能不仅取决于床垫的柔软度，还取决于底部床单/毛巾和床垫的组合。在所有层理中，面朝下体位的再呼吸潜力增加，仰卧位是最佳的CO2分散体位。
