Abstract: The present invention relates to a computer-implemented method for identification of the degree to which a transient disturbance in ventilation causes changes in measurement of arterial acid-base status.

Abstract: The present invention relates to a method for identification of tissue hypoxia from measurements of acid-base and oxygenation status from venous and/or arterial blood.

Abstract: The present invention relates to a system (10) and a corresponding method for estimating the respiratory drive (R_DRIVE) of mechanically ventilated patients, and for preferably apportioning this respiratory drive into one, or more, components related to the chemical drive—i.e. the drive due to the chemoreceptor response—and/or the muscular drive—i.e. the contraction of respiratory muscles, for example the diaphragm. The principle of the invention is that respiratory drive can be obtained from measuring the patient's response to small changes in mechanical ventilation settings (Vt_SET), and that this can be apportioned into chemical and/or muscular effects depending upon the changes in respiratory frequency, and/or arterial or end tidal CO2 levels, and/or arterial blood p H.

Abstract: A method is provided for identification of an increase in the gas volume of the lung caused by the inability of a patient to expire completely, known as dynamic hyperinflation or gas trapping.

Abstract: The present invention relates to intelligent monitoring of patient, where measured patient values are transformed into physiological parameters using physiological models. By using this transformation it is possible to more precisely assess the reason for changes in patient values or even identify worsening of the patient in the absence of changes in patient values.

Abstract: The invention relates to a mechanical ventilation system for respiration of a patient, the system being adapted for providing decision support for mechanical ventilation. Control means is adapted for using both first data and second data, indicative of the respiratory feedback in the blood, in physiological models (MOD) descriptive of, at least, lung mechanics, and/or gas exchange in the lungs of the patient, the physiological models comprising a number of model parameters (MOD_P). The control means is further arranged for simulating the effect on one, or more, model parameters (MOD_P) of the physiological models for a suggested value of the positive end expiratory pressure (PEEP) setting for the ventilation means, and thereby provide decision support in relation to said suggested PEEP value.

Abstract: The present invention relates to a decision support system (DSS), a medical monitoring system (100), and a corresponding method for identifying the need for measurement of cardiac output (CO) based on one or more comparisons (COMP1, COMP2) in a physiological model. More specifically, for identifying when an approximated value of CO cannot be correct due to circulatory compromise and as such that another estimated or measured value of CO is required.

Abstract: The invention relates to a device for determining two or more respiratory parameters relating to an individual and a method for determining two or more respiratory parameters relating to an individual by means of the device. The disclosed device and method may be used in an individual suffering from pulmonary gas exchange problems relating to gas exchange of oxygen and/or carbon dioxide, e.g. a patient with chronic obstructive pulmonary disease. The device and method may also be used in a healthy individual or in an animal, e.g. for research experiments. The device has detection means for oxygen and carbon dioxide contents in inspired and expired gas and blood.

Control means (12) is adapted for using both first data (D1) and second data (D2), indicative of the respiratory feedback in the blood, in physiological models (MOD) descriptive of, at least, lung mechanics, and/or gas exchange in the lungs of the patient, the physiological models comprising a number of model parameters (MOD_P).

Abstract: The present invention relates to a method for calibrating, or adjusting, the level of oxygen in respiratory gas related to the level of oxygen in the blood circulation of the individual, comprising providing a level of oxygen in the gas flow passing into, or out, of the respiratory system of the individual and producing a corresponding first output, providing a level of oxygen in the blood circulation of the individual and producing a corresponding second output, providing a computer for receiving and storing at least two measurements, each measurement being the concurrent output of said first output and said second output within a data structure, in which the two stored outputs are mutually related, in data storage means associated with the computer, the at least two measurements being conducted at respective levels of oxygen in the gas flow passing into the respiratory system, and calibrating the level of oxygen in the gas value in response to a delay between the level of oxygen in the blood circulation of

Abstract: A methodology for converting venous blood values to arterial blood values provides the advantage of obviating the need for taking arterial blood samples. The method entails (i) measuring arterial oxygenation, (ii) measuring and estimating values of venous blood acid/base status and oxygenation status of a venous blood sample, and (iii) converting the venous blood values by applying a mathematical model for deriving blood acid/base status and oxygenation status into estimated arterial blood values.
