Solution Overview & Benefits

Information updated: April 10th 2020

This is a Pump device.

This project documents the process of converting a low-cost CPAP (Continuous Positive Airway Pressure) blower into a rudimentary non-invasive pressure support ventilator that could help with breathing during respiratory distress. This project can also be used to create a reasonable low-cost Powered Air Purifying Respirator (PAPR) with filter adapter and mask. PAPRs are effective pieces of Personal Protective Equipment (PPE) that could be helpful to caregivers.

Summary Specs:

  • This is a Pressure Control Ventilation (PCV) device.
  • This rudimentary design can have a programmable breathing rate (ex: 10-16/min)
  • It can have a programmed Positive End-Expiratory Pressure (PEEP)
  • The blower is physically able to hit a peak airway pressure of up to 45cmH2O.
  • It cannot yet hit a target tidal volume.
  • Does not yet have alarms
  • Does not yet have back-up power supply.

Team Disclaimer: Whenever possible, please seek professional medical care with proper equipment setup by trained individuals. Do not use random information you found on the internet. I am not a medical professional, just a random person putting information on the internet. There are significant risks associated with using a high pressure BiPAP as a DIY ventilator without medical supervision.
