Breath gas analysis technology and the non invasive heart beat coming out quantity and the lung functional monitoring which use the physiology model

摘要

(57) Abstract The heart beat coming out quantitative monitoring system (10), includes the breath meter (14), and the gas analyzer (20 and 22) non measures each quality of each breath gas invasive and by the fact that the principle of Fick is applied can decide the heart beat coming out quantity in every breath. The above-mentioned gas analyzer has the function which by the fact that individual quality of the breath gas blend of the possible component of known quantity is measured in every breath quantifies plural vapor density such as inhalation density and expiration end density of the optional component of the above-mentioned breath gas blend simultaneously in real time. The above-mentioned breath meter decides the volume flow and mass flow rate of the optional single/plural vapors which in every breath in real time were calculated from the product of measurement end total breath flow and measurement end cubic measure density. The heart beat appearing quantity can be decided in every breath from these measurable quantities, by applying the appropriate numerical algorithm which is based, on the principle of Fick such that physiology condition of the short circuit and the dead cavity etc is revised.
