PATIENT CIRCUIT
​
​The entire patient circuit can be assembled at the point of use from standard, already approved
ICU parts.
MICRO-CONTROLLER SOFTWARE
​
The software running on the Arduino micro-controller provides fine control and several modes of operation.
CONTROL AND MONITORING SOFTWARE
​
The user control and monitoring software can run on any Windows 10 computer.
PROJECT COMPONENTS
PNEUMATIC DRIVE
​
​The bag-valve is compressed by a hinged paddle driven by a pneumatic cylinder inside a simple frame. The ventilator requires a source of compressed air or nitrogen at about 50 pounds per square inch (psi), or about 350 KPascals.
ARDUINO MICROCONTROLLER
​
The venilator is controlled by an Arduino microcomputer. ​The Arduino receives inputs from a pressure sensor and triggers a patient's breath immediately following the start of patient inhalation.
ELECTRONICS
​
In addition to the micro-controller there are two custom PCB boards. One holds the digital pressure sensors. The other holds the Arduino and various electronics that control the ventilator and display.
