Tidal Volume/Pressure modes are easily supported as seen in this test lung experiment. For other videos, see bottom of page.
Starting here as an idea, together with vendors, manufacturing and distribution partners, E5 Aerospace LLC has developed ventilators that can be manufactured and deployed rapidly around the globe with Commercial Off The Shelf*, locally sourced components. Our ventilators meet the safety and performance requirements characteristic of Class II medical devices and the range of ventilatory support needed. In the short term, we hope to address an emergency clogged by supply chain issues, in the long term we hope to transform the conversation around expensive medical devices. It is likely that we are being idealistic; but do come join our movement.
UK Rapidly Manufactured Ventilator System Specification Aimed at patients entering the acute stage.
Supports intubated and noninvasive application. Supports Pressure, Volume, and Synchronized modes and variations.
Filtered, heated, and oxygen- and moisture-mixed air with tunable
mixing ratio, flow rate, pressure and temperature. Air and virus filters, and water collectors standard Air supply provided by compressor with 50psi line/15lts/min (included).
Oxygen provided by concentrator or tank. Hospital lines can be connected.
Hospital lines can be connected.
We are presently working on low-cost concentrators
All plug-to-connect pneumatic circuitry
Embedded Microcontroller + PC (v1)
Ardupilots repurposed (v0)
Stepper motors (v3), high-reliability PWM servos (v2), hobby servos (v1), manual (v0)
Soft-start valves standard.
Sensing for static and dynamic pressure, temperature, humidity, and concentration (v2). New spirometer designs.
Hybrid technology: Uses physical principles and machine learning to derive high performance from few generic components (v3) Robotic manufacture of kits for rapid, scalable, and cost-effective national outreach.
COTS locally sourced options for international use.
24/7 and emergency systems.

We are in the pre-manufacturing stage. We are presently working on regulatory authorizations.
We aim to move from the prototype phase to a manufacturing process that is scalable.
Mark 1 is for export (pranayantra py20M1)
Mark 2 for US (EVA py20M2)
