  • Automatic electronic apparatus for measuring the bronchial resistance and the elastance of the pulmonary tissue
    Patent number: 4036222
    Abstract: The invention relates to medical science.According to the invention, the resistance to air flow through the bronchial tracts and the elastance of the pulmonary tissue are measured and displayed, starting from signals which represent the respiratory air flow and the variation in endothoracic pressure, by means of an apparatus which comprises a flow signal preamplifier, a pressure signal preamplifier, two automatic calculating devices and an electronic control combination.The apparatus makes it possible to use endothoracic pressures measured via the central venous system and can possess an alarm signal which is triggered automatically if the values displayed are memorized values.
