  1. 1. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Samuel Eriksson; [2022]
    Nyckelord :Mechanical ventilation; high frequency ventilation; patient circuit dynamics; parameter estimation; system identification; Mekanisk ventilation; högfrekvent ventilation; patientkretsens dynamik; parameterestimering; systemidentifiering;

    Sammanfattning : Artificial breathing is vital when it comes to treatment of critically ill patients where the natural breathing mechanism is insufficient. With the help of mechanical ventilators, the natural breathing mechanism of the patient can be assisted or even exchanged with the artificial breathing from the machine. LÄS MER

  3. 2. Current Control and Modelling of an Inspiration Valve

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Astrid Lindstedt; [2021]
    Nyckelord :Current Servo; Cascade Control; Solenoid Model; Ventilator; Strömregulator; Kaskadreglering; Solenoid modell; Respirator;

    Sammanfattning : An analog current servo of an intensive care ventilator is being developed at Getinge in Stockholm. The current servo is used to control the output gas flow of an inspiration valve to a patient’s lungs. The ventilator’s control system is in a cascade design of two closed-loops, of which the current servo is the controller for the inner loop. LÄS MER
