Abstract: The present invention relates to a system for indicating an at-risk situation for a lung ventilator, comprising a screen (1) that displays at least one fixed-size drawing element (2) representing the lungs being ventilated, in which the shade of the drawing element switches according to predetermined criteria.

Abstract: An auxiliary device and a method for estimating the muscle pressure of a patient being ventilated by a pulmonary ventilator is provided which comprises creating the database that correlates data on pressure, volume and flow of pulmonary ventilator respiratory cycles with muscle pressure data corresponding to the pressure, volume and flow data of the ventilator; using the database to create a training data set; training a predictive time-series algorithm with the training data set; populating the algorithm with pressure, volume and flow data from a pulmonary ventilator, in which the pressure, volume and flow data include at least a time series with pressure, volume and flow curve points; and using the algorithm to estimate the muscle pressure value for at least one of the time series points.

Abstract: A transportable lung ventilator allowing for automatic selection between oxygen and air for feeding a venturi type ventilation system comprising a monobloc body with at least one medical oxygen inlet; at least one compressed air inlet; and at least one ambient air inlet; at least a selector valve integrated with the monobloc body and adapted to allow, selectively, the passage of medical oxygen or compressed air; a venturi system, internal to the monobloc body, comprising an injector nozzle and a venturi tube, the injector nozzle receiving the medical oxygen or the compressed air passing through the selector valve and generating a jet towards the venturi tube, the jet dragging ambient air through the ambient air inlet to generate a mixture of gases to be ventilated to a patient; a fraction of inspired oxygen sensor that measures the concentration of oxygen in the gas mixture; and an electronic control system that controls the selector valve to allow the passage of medical oxygen or compressed air based on the

Abstract: An object of the present invention is to provide a method of detecting a nucleic acid binding protein and a method of screening for a binding inhibitor or promoter for a nucleic acid binding protein. According to the present invention, there is provided a method of detecting binding between a nucleic acid and a nucleic acid binding protein, comprising determining the degree of structural change in a nucleic acid complex having at least two nucleic acid duplex moieties.
