A respirator with an adjustable pressure or volume flow curve has a control and analyzing unit, which is set up to determine the resistance R and the alveolar pressure Palv(t). The control and analyzing unit checks the functional dependence of Palv(t) and of the tidal volume Vol(t) for time intervals in which an indicator of the quality of a linear functional dependence of Palv(t) and Vol(t) meets a preset threshold criterion and to determine the elastance E or compliance C from the rise of the alveolar pressure Palv(t) as a function of the volume Vol(t) only in the time intervals thus determined.

An electrode belt is provided for carrying out electrodiagnostic procedures on the human body. The electrode belt includes a belt (2), which is formed at least partially of an elastic material and surrounds the body of a test subject. A plurality of electrodes, are mechanically connected to the belt and are in flat contact with the body of the test subject. At least one contact passes from the electrodes through the belt (2) and is connected to a connection element (11), which is connected to a lead each of a multicore cable (6). Such an electrode belt offers marked advantages in terms of handling along with increased safety from movement artifacts.
摘要:
An anesthesia device has a device (4, 5) for the supply of at least one first anesthetic and a second anesthetic in a quantitatively settable, controlled manner. A data processing unit (6) with a corresponding display (8) is set up for determining the current concentrations in the plasma or at the site of action from continuously supplied data on the quantities of the anesthetics administered with a module (10) for a pharmacokinetic compartment model calculation and for storing these concentration values. Concentration data is predicted for at least one point in time in the future and this is also calculated. An action module (20) keeps ready the curve of at least one anesthesia action parameter as a function of the concentrations of the anesthetics in a stored manner. A display module (30) displays on the display (8) at least one action diagram, in which the concentration of the first or second anesthetic as well as the sequence of the concentration data of the anesthesia curve obtained up to that point in time are displayed and the predicted concentration data are displayed with a separate symbol. In case of comparison with concentration set points, it is also possible to act automatically on the feed of the anesthetics in a controlled manner with the predicted concentrations.

A device for releasing breathing gas establishes constant flow conditions for the breathing gas being discharged. An annular connection element (6) is provided between an outer part (2) and an inner part (4), and a discharge gap (7) is formed between the connection element (6) and the outer part (2).
摘要:
A method is provided for automatically controlling a ventilation or breathing system with a ventilation unit (7), which is controlled by a control unit (5), in order to deliver an assist pressure preset by the control unit, wherein the current values of the tidal volume flow Flow(t) and those of the volume V(t) are detected in the control unit. The control unit (5) may carry out a proportionally assisting ventilation method (PAV: Proportional Assist Ventilation) by a factor for a degree of compensation (PPSp) being selected by the control unit and by the parameters for the volume assist (VA) and the flow assist (FA) being determined by: VA=PPSp·ΔE FA=PPSp·ΔR, wherein ΔE is the deviation of a measured or assumed elastance (Emeasured) of the patient from an ideal elastance (Eideal) and ΔR is the deviation of a measured or assumed resistance (Rmeasured) of the patient from an ideal resistance (Rideal). The assist pressure PS(t)=VA·V(t)+FA·Flow(t) is determined from this by the control unit with the flow delivery device (ventilation unit (7)) being set such as to deliver this assist pressure.
摘要:
A device is provided for the output of medical data with an output device (1) for the output of medical data in a first output mode or in a second output mode different therefrom. The device includes a detection device (3, 4) for detecting an ambient parameter and an automatic switchover device for the output of medical data in the first output mode if the ambient parameter detected by the detection device is in a first range of values, and for the output of medical data in a second output mode if the ambient parameter detected by the detection device is in a second range of values different from the first range of values.
