    摘要： A stretchable belt (1) provided for medical purposes for use on the body of a patient has at least one sensor (8) for detecting at least one parameter of the patient's body. An adaptation to different body sizes and motions of the patient is provided without separate length adjusting members being necessary or without the need to stock different belt sizes. Furthermore, the belt is able to be manufactured at a low cost and makes possible simple and reliable handling, even for patients. The belt material (1) has at least one material area (2) with a lower spring rate in the longitudinal extension than at least one material area (3) with a higher spring rate of the belt (1).

    摘要： A method of non-invasively estimating the intrapulmonary shunt in a patient. The method includes non-invasively measuring respiratory flow, respiratory carbon dioxide content, and arterial blood oxygen content. A re-breathing process is employed to facilitate an estimate of the patient's pulmonary capillary blood flow. Any inaccuracies of the arterial blood oxygen content are corrected to provide a substantially accurate arterial blood oxygen content measurement. The respiratory flow, carbon dioxide content and arterial blood oxygen content measurements, and the pulmonary capillary blood flow estimate are employed to estimate an intrapulmonary shunt of the patient. The invention also includes a method of determining the total cardiac output of the patient which considers the estimated intrapulmonary shunt.

    摘要： Methods for noninvasively determining a pulmonary capillary blood flow or a cardiac output of a subject include determining data of the amount of gas exchanged between blood and gas in lungs of the subject, as well as data of an indicator of the content of the gas in blood of the subject. Such a determination may be made during two or more different states of ventilation. A geometric relationship is identified between data points, with any data points outlying the geometric relationship being disregarded. The remaining data points may be used to estimate or calculate a measure of pulmonary capillary blood flow or cardiac output. Systems that include elements that are configured to effect such methods are also disclosed.

    摘要： Methods for estimating the volume of the carbon dioxide stores of an individual's respiratory tract include determining a carbon dioxide store volume at which a correlation between corresponding signals of carbon dioxide elimination and an indicator of the content of carbon dioxide in blood of the individual is optimized. The estimate of the volume of carbon dioxide stores, which comprises a model of the respiratory tract, or lungs, of the individual, may be used as a transformation to improve the accuracy of one or both of the carbon dioxide elimination and carbon dioxide content signals. Transformation, or filtering, algorithms are also disclosed, as are systems in which the methods and algorithms may be used. The methods, algorithms, and systems may be used to accurately and noninvasively determine one or both of the pulmonary capillary blood flow and cardiac output of the individual.

    摘要： A method of compensating for non-metabolic changes in respiratory or blood gas parameters including generating a compensatory signal based on the magnitude of the non-metabolic change and the amount of time elapsed since the onset of the non-metabolic change. The method of the present invention is useful for compensating for non-metabolic changes in non-invasive carbon dioxide elimination measurements and, particularly, when carbon dioxide elimination is employed to determine cardiac output on a non-invasive, continuous basis.

    摘要： A re-breathing method for determining pulmonary capillary blood flow that accounts for changes in the cardiac output or in the carbon dioxide content of the venous blood of a patient. The carbon dioxide elimination and partial pressure of end tidal carbon dioxide of the patient are non-invasively measured prior to re-breathing, during re-breathing, and after re-breathing. The carbon dioxide elimination and the carbon dioxide content of the alveolar blood of the patient at each of the before, during, and after re-breathing phases are then used to calculate the pulmonary capillary blood flow of the patient. A rate of change of carbon dioxide content of the venous blood of the patient may also be calculated and employed in calculating the pulmonary capillary blood flow of the patient.

    摘要： A compressed air respirator with prolonged operating time due to rebreathing. The compressed air reservoir includes a compressed air reserve with a connected demand air supply valve, a reversible breathing gas reservoir (4) with a registering device (5) detecting the filling level of the breathing gas reservoir (4), and with an inspiration and expiration line (7, 8) for the user of the apparatus. A valve (6) is connected with the inspiration and expiration line (7, 8) and, on the inlet side, with the compressed air reserve (1) with a demand air supply valve (2) and with the breathing gas reservoir (4) and, on the outlet side, with the ambient air (11) and with the breathing gas reservoir (4). The valve means (6) is cyclically reversed by the registering device (5) in two phases such that depending on the filling level of the breathing gas reservoir (4), the inspiration line (7) is first connected with the compressed air reserve (1) and the expiration line (8) with the breathing gas reservoir (4) during a first phase until the filling level of the breathing gas reservoir (4) reaches an upper reversing point for the valve means (6), so that the inspiration line (7) is connected with the breathing gas reservoir (4) and the expiration line (78) with the ambient air (11) during a second phase until the filling level of the breathing gas reservoir (4) reaches a lower reversing point for the valve means (6) and the latter is again reversed as in the first phase.
