Canterbury University researchers have invented a device that would double the capacity of ventilators used for the treatment of Covid-19.
Titled the "Active Close-loop Timed-in-series Inspiratory Valve" or ACTIV system, it will mean two people can use a ventilator at the same time.
Professor Geoff Chase said they are feeling hopeful about the device.
"We believe this can, and will, save countless lives internationally by doubling ventilator capacity and sparing doctors from having to make terrible end-of-life care choices.
"It will help health systems to weather the Covid-19 pandemic storm when major outbreaks occur by increasing intensive care capacity."
