本文从舒适性、方便性和合身性三个方面研究了四种不同类型的英国产防脱鞋在斯里兰卡（一个发展中国家）的适用性和有效性。通过客观和主观评估来评估患者的不适程度和对感官使用的干扰程度。研究发现，呼吸阻力、运动强度和活动时间等因素影响生理反应。呼吸机重量和皮肤温度与心血管应激无直接关系。正压呼吸器的面部温度比负压面罩低，这使这种呼吸器在炎热环境中具有额外的优势。限制下颌运动的呼吸器会影响佩戴者的语言清晰度。口鼻面罩比其他类型更限制视力。尽管英国人和斯里兰卡人的头部和面部尺寸有很大差异，但他们的配合问题可以忽略不计。主观评价与客观测试相关良好。
The suitability and effectiveness of four different types of British made respirators were studied with respect to comfort, convenience and fit on wearers in Sri lanka (a developing country). Objective and subjective assessments were made to evaluate the degree of discomfort and interferences to the use of senses. The study revealed that factors such as breathing resistance, work-rate and activity period affected the physiological responses. The weight of the respirator and the skin temperature had no direct relationship with the cardiovascular stress. Positive-pressure respirators that gave lower face temperatures than negative-pressure masks gave this type of respirator an additional advantage in hot environments. Respirators that restricted jaw movement affected the speech intelligibility of the wearer. Orinasal masks restricted vision more than the other types. The problem of fit was found neglible though head and face dimensions significantly differed between the British and the Sri Lankans. Subjective assessment correlated well with objective tests.
