جهاز تنفس صناعي (Breath team).


Controller

We used the Arduino Microcontroller with the following blocks

  • Pneumotachometer: measures the lung volume by transducing pressure to voltage
  • Spirometer: measures static pulmonary volume which indicates
  • Tidal volume: Amount of gas inspired or expired at each breath
  • Inspiratory reserve volume: Maximum amount of additional air that can be inspired at the end of a normal inspiration
  • Expiratory reserve volume: Maximum amount of additional air that can be expired at the end of a normal expiration
  • Residual volume: The volume of air remaining in the lungs after a maximum expiration
  • Flow measurement: During inspiration the gas flows from the ventilator to the patient, A measure that total pressure, B measures the static pressure, the difference is the dynamic pressure which proportional to the velocity of gas flow. During expiration the process is reversed. C measures CO2, O2
  • Breathing Controller
  • Alarm system: The alarm indicates different patient parameter such as exhaled volume or airway pressure, also the ventilation system shall detect whether a breath has been taken or not. Measuring changes in aspiratory flow and pressure by using sensors. If no inspiration was detected for a certain time an alarm will be triggered.
  • Human interface
