Table of Contents

Getting-Started

  • Buy the materials.
  • Construct your mechanical and neumatic system.
  • Connect the electrical components.
  • Test your mechanical work to check his functionality.
  • Download the code and program.
    • First load each test on test folder to try individually the components and check his work.
    • If the interface will be via serial port program OpenSourceVentilatorSerial
    • In case you have an ESP8266 and want to control it via Wi-Fi connect your ESP-8266 to the arduino and load the ESP-8266 code together with the OpenSourceVentilatorSerial code

Objective

To design a low cost/ high sofisticated respirator using local materials

Requirements

id Name Value Implementation
a Volume 0.2 -> 1 Liter Ambu-size
b PEEP (Positive end-expiratory pressure) 5 -> 20 cmH2O Ambu valve
c FiO2 21 -> 100% Mixture using air valves
d Relation inspiration - expiration 1:1 - 1:3.2 Time or Frecuency using Potentiometer (P1)
e PIP (Peak inspiratory pressure) 5-80 cmH2O Pressure sensor measured and programmed using Potentiometer (P2)
f Volume-control or Pressure-control option 1 or option 2 3 positions button (SW1)
g Alarm Buzzer Pre-programmed
h Frecuency respirated 6 - up to 35/minute Speed of motor Potentiometer (P3)
i Valve pressure relief - Volume sensor - Flow sensor Mechanic and electronic devices and accesories Sensors
