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 method for the supervision of injection molding including monitoring an internal die pressure of molten resin flowing through a resin passageway in a mold to form a monitored waveform; displaying the monitored wavefrom together with a predetermined reference waveform on a display unit such as a CRT, and comparing the monitored waveform with an allowable value of the reference waveform to determine any abnormality caused in a molding process. The injection molding can be supervised with accuracy on the basis of the reference waveform representing the optimum internal die pressure, thereby increasing the quality of molded articles.
