A self contained life support system which can maintain a breathable atmosphere for up to eight hours was recently developed for use with a portable hyperbaric tent. To facilitate further life support system studies, the practicality of a human breathing simulator (HBS), which would remove oxygen and release carbon dioxide at the same rate as a human, was tested. The HBS consists of a cylinder of carbon dioxide bled into the chamber via a flow regulator and a Vanadous bubbler to chemically remove oxygen from the chamber. First experiments show that the HBS works, but that a larger chemical system is needed to remove oxygen at the desired rate. Scale up calculations have been completed.
最近开发了一种独立的生命支持系统，该系统可为便携式高压氧舱维持长达八小时的可呼吸大气。为了便于进一步开展生命支持系统研究，对一种人体呼吸模拟器（HBS）的实用性进行了测试，该模拟器能以与人体相同的速率去除氧气并释放二氧化碳。HBS由一个二氧化碳气瓶组成，该气瓶通过流量调节器和一个钒鼓泡器将二氧化碳注入舱室，以化学方式从舱室中去除氧气。初步实验表明HBS可行，但需要更大的化学系统才能以所需速率去除氧气。放大计算已经完成。
