我们开发了一种用于氧气管理的新面罩概念，使用非织造布。这项研究的目的是评估新面罩是否在不影响氧气输送和二氧化碳消除的情况下提高了可接受性。10名健康成年志愿者被随机分为传统塑料口罩第一组和新型口罩第一组。参与者被要求在坐着时佩戴分配的口罩，氧气浓度为3分L/分钟，持续10分钟。通过位于口部的采样管测量呼气末O2浓度(ET-O2)和呼气末CO2浓度(ET-CO2)。休息10分钟后，以同样的方式测试另一个面罩。面罩的不适感使用100M视觉模拟评分进行评估，其中0， 舒适，100， 不舒服。结果显示，使用新型口罩引起的不适感明显低于传统口罩(新型口罩11只，传统口罩33只)(P= 0.002)。新型面罩的ET-O2中位数为33%，传统面罩为30%(P= 0.008)。ET-CO2 BY面罩类型(新面罩32 mm Hg，传统面罩30 mm Hg)无显著差异。综上所述，新型面罩比传统面罩更舒适，并能提供更高的ET-O2。
We developed a new face mask concept for oxygen administration using non-woven textiles. The aim of this study was to evaluate whether the new mask improves acceptability without compromising O2delivery and CO2elimination. 10 healthy adult volunteers were randomized to either the conventional plastic face mask–first group or the new face mask–first group. Participants were asked to wear the assigned mask with O2at 3 L/min for 10 min while seated. End tidal O2concentration (et-O2) and end tidal CO2concentration (et-CO2) were measured via a sampling tube located at the mouth. After a 10-min rest period, the other mask was tested in the same manner. Mask discomfort was evaluated using a 100 mm visual analog scale (VAS) where 0, comfortable and 100, uncomfortable. The results showed that use of the new mask caused less discomfort than the conventional mask (new, 11; conventional, 33) (P= 0.002). Median et-O2with the new mask was 33%, compared with 30% with the conventional mask (P= 0.008). There were no significant differences in et-CO2by mask type (new, 32 mmHg; conventional, 30 mmHg). In conclusion, the new mask was more comfortable and provided higher et-O2than the conventional mask.
