Vapor phase type breath functional measuring method and uses the measurement result the vapor phase type breath functional health care manner

摘要

PURPOSE:To provide a method for managing health of a gaseous phase system respiratory function meeting a change of living habits by generally measuring the gaseous phase system respiratory function by using an inhalation gas distribution rate, residual air gas rate, carbon monoxide lung diffusing capacity and oxygen consumption demand index and using the results thereof. CONSTITUTION:A testee holds a pipe in his mouth and sucks the air contg. the carbon monoxide of a known concn. of about 0.3% (concn. F1(CO)) and helium of a known concn. of about 10% (concn. F1(He)) as much as possible. A suction amt. V1 is measured and after the testee is ordered to stop the respiration for about 10 seconds (t second), the testee is instructed to exhalate the air as much as possible. The residual amt. exclusive of a part having a possibility of mixing with the first dead space gas of the exhalated gas is drawn and the concn. FE(CO) of the carbon monoxide and the concn. FE(He) of the helium in the drawn gas are measured. The absorbed gas distribution rate FE(He)/F1(He)%, simple residual air rate RV'%, carbon monoxide lung diffusion capacity DL(CO) and oxygen consumption demand index DELTAP(CO)/t are calculated.
