PROBLEM TO BE SOLVED: To provide a monitor system for evaluating the respiration and respiratory organs of a patient.SOLUTION: A monitor system displays, for each breath, a rectangle illustrating a concentration-ventilation volume loop and a Bohrs equation and having an area of VCO2, and a rectangle inscribed in the concentration-ventilation volume loop and having a maximum area, in the same xy coordinates. In addition, the monitor system displays, on predetermined areas of a display device screen, an excretion amount VCO2, an alveolar gas concentration, an exhalation terminal CO2 concentration, a mixed exhalation concentration, a respiration dead space volume VDresp, an alveolar ventilation volume VA, an air duct dead space volume VDaw, and an alveolar dead space volume VDalv of CO2 gas for each breath.COPYRIGHT: (C)2014,JPO&INPIT【課題】患者の呼吸及び呼吸器を評価するモニタシステムを提供する。【解決手段】1呼吸毎に、濃度-換気量ループ、ボーア式を図示する面積VCO2の長方形、及び濃度-換気量ループに内接する面積極大の長方形を、同一のX-Y座標に表示し、さらに1呼吸毎のCO2ガスの、排泄量VCO2、肺胞気濃度、呼気終末CO2濃度、混合呼気濃度、呼吸死腔量VDresp、肺胞換気量VA、気道死腔量VDaw、及び肺胞死腔量VDalvを、表示装置の所定の領域に表示する。【選択図】図5
