    摘要: A device for compensating for flow resistance in an expiratory section of a ventilator system has a bellows system whose increase in volume during expiration is regulated by a regulatory device and a control unit, so that expired gas fills the bellows system. The increase in volume is regulated according to values measured for pressure so virtually complete compensation for flow resistance is attained. Pressure is measured with a first pressure gauge located by the bellows system, and a second pressure gauge located by the patient. The device can be a separate apparatus which is connectable to a ventilator, or can be totally integrated into the ventilator.

    摘要: In a method for controlling an expiratory valve in a ventilator during expiration, the expiratory valve is opened substantially fully for a first interval. Fully opening the expiratory valve has the advantage of minimizing the expiratory resistance a patient needs to overcome. Keeping the expiratory valve open as long as possible during expiration, without losing control of positive end expiratory pressure (PEEP), is therefore advantageous. An optimal system is achieved. In a method wherein pressure in the expiratory section of the ventilator is measured during a second interval, the expiratory valve is regulated so a predetermined end pressure is obtained in the expiratory section, and at least one parameter, directly or indirectly related to control of the expiratory valve, is determined, and a determination is made from that parameter as to whether the next first interval for the next expiration should be longer than, shorter than or as long as the first interval.

    摘要: A method of obtaining an indication of the position of an esophageal catheter inserted into a patient includes the steps of obtaining an electrical signal from the esophageal catheter, determining an ECG component of the electrical signal, determining the widths and/or rate of a number of periods in which the ECG component exceeds a threshold value, using the rate or widths of the periods to determine the presence of a P-wave in the ECG component, and concluding that the catheter is in a good position for obtaining a correct EMG signal if a P-wave is determined to be present. If not, the position may be corrected. The method may be performed by a control unit in a ventilator or a monitoring device.

    摘要: A method and apparatus for filtering an electromyogram (EMG) signal from a raw signal which includes a contribution from an electrocardiogram (EKG) signal is disclosed. The method includes the steps of estimating an attribute (such as a Fourier transform) of both the EMG contribution to the raw signal and the EKG contribution to the raw signal and, dependent on both frequency spectrums, determining an EMG window in a frequency range and obtaining the EMG signal by passing it through a filter defined by the frequency range. The method is particularly used when monitoring a multi-channel electrical recording from a plurality of electrodes attached to a patient's diaphragm.

    摘要: A valve assembly HAS an element movable in a mechanical journal arrangement relative to a valve opening to establish an opening position of a valve, and A control unit for controlling the application of an oscillatory electromagnetic force to the element (8) having an known peak amplitude to cause the element to execute a sympathetic oscillatory motion as a friction reducing maneuver. The control unit is adapted to control the peak amplitude of the oscillatory electromagnetic force to sequentially apply a number of different peak amplitudes, each during a different measurement period. A monitor detects changes in the opening position of the valve during each of the measurement periods and provides a measure thereof. A processor is connected to the control unit and to the monitor to determine a working amplitude of the oscillatory electromagnetic force at which the detected changes will be minimized and to supply the determined working amplitude to the control unit.
