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.
