4. 3. Dynamic Modelling of the Patient Circuit for High Frequency Ventilation

   University essay from KTH/Maskinkonstruktion (Inst.)

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

   Abstract : 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. READ MORE

5. 4. Current Control and Modelling of an Inspiration Valve

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

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

   Abstract : 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. READ MORE

6. 5. A study on gas-module test-system to attain high precision gas-flow control in medical ventilators

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Vishnu Narayanan; [2021]
   Keywords : Gas-flow control; calibration of gas flow controller; trimming of gas-module; flow measurement; Gasflödesreglering; kalibrering av gasflödesregulatorn; trimning av gasmodul; flödesmätning;

   Abstract : A medical ventilator is a life-sustaining device that helps critically ill patients with complete or partial breathing support. It provides a patient with the right amount of air and/or oxygen as per requirement. It is therefore essential to have a highly accurate device controlling the flow of these essential gases. READ MORE
