Abstract: A process adjusts a ventilation parameter (40) for a ventilation process (90) of a patient (110), which is carried out by a ventilator (20). Electrical impedance tomographic (EIT) data (70) of the lungs (111) of the patient (110), concerning the ventilation process (90), are collected by an EIT device (30). An adjusting device (1), adjusting a ventilation parameter (40) for the ventilation process (90), has an analysis unit (2) with a memory (3), a data input unit (5) data-communicatingly connected to the analysis unit (2) for receiving data and a data output unit (7) data-communicatingly connected to the analysis unit (2) for outputting data. A medical system (100), includes a ventilator (20), an EIT device (30) as well as the adjusting device (1) for adjusting a ventilation parameter (40) for the ventilation process (90) of a patient (100).

Abstract: A ventilator (1), for ventilating the lungs of a patient with breathing air, includes a ventilation module (2) for generating a breathing air flow, a determination module (3) for determining a first ventilation parameter as well as a different second ventilation parameter of the ventilator, and a control module (4) for controlling the ventilator as a function of the determined first and/or second ventilation parameter. The control module is configured to reduce the first ventilation parameter automatically over an analysis period including at least one breathing cycle. A classification module (5) is configured to classify a pulmonary status of the lungs of the patient based on a change in the second ventilation parameter, which change was brought about by the automatic reduction of the first ventilation parameter. A process is further provided for ventilating the lungs of a patient with breathing air with a ventilator (1).

Abstract: A medical device (100) determines a resistance parameter (107), of a patient to be treated, indicating a peripheral vascular resistance. A reception module (110) is configured to receive a pulsatile signal (112). The pulsatile signal indicates a blood pressure curve (114), especially an arterial blood pressure curve, or a blood volume curve. A reading module (120) is connected to the reception module and is configured to read a number of predefined curve parameters (124) from the received pulsatile signal and to provide corresponding, read measured values (134) for the number of predefined curve parameters. A calculation module (130) is connected to the reading module and is configured to calculate the resistance parameter of the patient with the use of a predefined estimation function (136) based on the read measured values and on a predefined parameter (135) indicating the cardiac output of the patient and to output same.

Abstract: A process, a signal processing unit and to a ventilator automatically calculate a set point for a frequency, with which the ventilator performs ventilation strokes and thereby mechanically ventilates the patient. An alveolar or proximal minute volume is predefined. A lung time constant for the lungs of the patient is determined. The volume of a dead space in a fluid connection between the lungs and the ventilator is determined. A mandatory frequency set point (fset,mand) for the mandatory ventilation of the patient is calculated. An ideal frequency (fspon), with which the patient can achieve the minute volume by means of spontaneous breathing, is calculated. The ventilation frequency set point is calculated as a weighted average of the mandatory frequency set point (fset,mand) and of the ideal frequency (fspon). The averaging depends on a determined actual intensity of the spontaneous breathing of the patient.

Abstract: A medical device (100) determines a cardiac output-dependent parameter (105) of a patient to be treated. A reception module receives a pulsatile signal (112) that indicates a blood pressure course (114). A storage module provides a model rule (122), describing an assignment between a number of predefined blood pressure course parameters (124) and the cardiac output-dependent parameter (105) to be assigned. A read-out module reads out the number of predefined blood pressure course parameters from the indicated blood pressure course and provides corresponding read-out measured values (132). A calculation module calculates and outputs an output value (142) for the cardiac output-dependent parameter (105) to be assigned based on the read-out measured values for the number of predefined blood pressure course parameters using the model rule, which is based at least partially on an end-systolic state (116) of a respective blood pressure pulse (115) of the blood pressure course.

Abstract: A medical system (6000) includes an EIT module (30, 33, 8000), a ventilation module (7100), a dosing module (4), a data input module (50) and a control module (70). The control module (70) coordinates a breath-hold maneuver, which is carried out at the ventilation module (7100). The control module (70) coordinates a perfusion measurement and a data acquisition (50) of EIT data (3), which is carried out at the EIT module (30, 33, 8000). The control module (70) determines an indicator, which indicates a state of perfusion of the lungs, and makes this indicator of the state of perfusion of the lungs available.
