日本肺疾病患者近120万人,据说其中50万人有呼吸困难症状,最近查明引起呼吸困难原因之一是呼吸肌的功能降低。新技术事业团把研制能有效地诊断呼吸肌异常的“呼吸肌功能测定装置”工作委托给医疗机器骨干制造厂家Chest公司。此装置是东北大学医学部的滝岛任教授的研究成果此装置由呼吸回路、循环回路、气体量测定装置及数据分析部分构成。被测定的人先吸氧,以呼出的二氧化碳气量来测定膈肌及肋间肌等使肺收缩,扩张的肌肉(呼吸肌肉)消耗氧的量。在健康人即使呼吸量增加,呼吸肌肉氧的消耗量也不怎么增加,但呼吸 Nearly 1.2 million patients with lung diseases in Japan are said to be among 500,000 people with dyspnea. One of the causes of dyspnea recently identified is the reduced functioning of the respiratory muscles. The new technology group has commissioned the Chest Company, a medical machine manufacturer, to develop a “respiratory muscle function test device” that can effectively diagnose respiratory abnormalities. This device is a research result by Professor Hiroshi Naohiro of Tohoku University School of Medicine This device consists of a breathing circuit, a circulation loop, a gas measuring device, and a data analysis section. The measured person first oxygen, exhaled carbon dioxide gas volume to measure the diaphragm and intercostal muscles such as the lung contraction, expansion of muscle (respiratory muscles) the amount of oxygen consumed. In healthy people, even if the respiration increases, the respiratory muscle oxygen consumption does not increase much, but the respiration
