    摘要: Methods for noninvasively measuring, or estimating, functional residual capacity or effective lung volume include obtaining carbon dioxide and flow measurements at or near the mouth of a subject. Such measurements are obtained during baseline breathing and during and shortly after inducement of a change in the subject's effective ventilation. The obtained measurements are evaluated to determine the amount of time required for exhaled carbon dioxide levels to return to normal—effectively an evaluation of carbon dioxide “washout” from the subject's lungs. Conversely, carbon dioxide and flow measurements may be evaluated to determine the amount of time it takes carbon dioxide to “wash in,” or reach peak levels within, the lungs of the subject following the change in the subject's effective ventilation. Apparatus for effective such methods are also disclosed.

    摘要: Methods for noninvasively evaluating indicators of cardio-pulmonary performance of a subject, such as cardiac output, pulmonary capillary blood flow, and blood carbon dioxide content, include obtaining data of an expiratory carbon dioxide signal and comparing data generated by an algorithmic lung model to the data of the expiratory carbon dioxide signal of a subject. The variables that are input into the algorithmic lung model are adjusted until the data generated thereby reflects that of the measured expiratory carbon dioxide signal with a desired degree of accuracy. Once the algorithmic lung model replicates the data of the measured expiratory carbon dioxide signal with the desired degree of accuracy, one or more of the input values may be used to determine one or more of the cardiac output, pulmonary capillary blood flow, or a blood gas content of the subject from which the expiratory carbon dioxide signal was obtained.

    摘要: Methods for non-invasively determining the cardiac output or pulmonary capillary blood flow of a subject include monitoring the subject's respiration during two ventilatory states. Such a method may include determining parameters of at least one of the ventilatory states based on one or more characteristics of the subject. Data obtained from monitoring the subject's respiration, such as an amount of gas present in exhaled gases and respiratiory flow, may be used to estimate respiratory or blood gas parameters, such as an amount of gas exchanged between blood and gases in the subject's lungs or an indicator of a content of the gas in the subject's blood.
