A lung for all: Novel mechanical ventilator for emergency and low-resource settings.

ABSTRACT:

Aims

To create a low-cost ventilator that could be constructed with readily-available hospital equipment for use in emergency or low-resource settings.

Main methods

The novel ventilator consists of an inspiratory limb composed of an elastic flow-inflating bag encased within a non-compliant outer sheath and an expiratory limb composed of a series of two, one-way bidirectional splitter valves derived from a self-inflating bag system. An Arduino Uno microcontroller controls a solenoid valve that can be programmed to open and close to produce a set respiratory rate and inspiratory time. Using an ASL 5000 Lung Simulator, we obtained flow, pressure, and volume waveforms at different lung compliances.

Key findings

At a static lung compliance of 50 mL/cm H₂O and an
