This ventilator uses a bellows for volume and pressure actuated by a stepper motor. The stepper motor is controlled in this unit by a raspberry pi with 7” touchscreen. The PI controls the motor by increasing or decreasing speed for adjustable pressure, increasing or decreasing stroke for adjustable volume and allowing for breathing cycles between 10 and 30 breaths per minute. The PI also controls a 12v air valve in adjustable increments for oxygen volume per breath. It will monitor incoming oxygen pressure and power levels along with battery backup life with alarms to notify of loss of either.
