The machines are cheaper to produce too and cost about £3,300 each compared to the £12,000 cost of a typical VC70 ventilator used in intensive care units.

Covid can lead to lung damage, making it far harder to get vital oxygen into the  trial – across 48 hospitals in the UK – aimed to discover the best way of delivering extra  researchers say the findings will help patients in the UK and in countries with limited
