作者对29名哮喘病人进行了有关氧消耗和 CO_2生成量的检测,以探讨哮喘患者呼吸肌的氧耗。29名患者均是近期急性发作刚得到基本缓解的病人,并达到公认的哮喘标准。研究在三种不同条件下进行,即①用咬嘴(戴鼻夹)呼吸室内空气;②用密封面罩呼吸室内空气;③用密封面罩吸氧(4～6L/min)。观察胸廓和膈肌移动以测定每分钟通气量,呼出之气体收集于 Douzlas 袋中,用分光光度计测量其所含氧气和CO_2的百分比,再换算成分压,用标准公式计算吸气与呼气之间潮气量之差以计算氧耗,同时测定动脉血
The authors performed tests on oxygen consumption and CO 2 production in 29 asthmatic patients to investigate the oxygen consumption of respiratory muscles in asthmatic patients. All 29 patients were those who had just received a basic remission of their recent acute exacerbations and reached the accepted asthma criteria. The study was conducted under three different conditions, namely ① breathing the air in the mouth with a mouthpiece (wearing a nose clip); ② breathing the room air with a sealing mask; and ③ breathing oxygen (4 to 6 L / min) with a sealing mask. Observe the movements of the thorax and diaphragm to determine minute ventilation. The exhaled gas is collected in a Douzlas bag and measured for the percentage of oxygen and CO 2 contained therein using a spectrophotometer. The gas is then converted to partial pressure and exhaled and exhaled The difference between the tidal volume to calculate oxygen consumption, arterial blood determination at the same time
