Our engineers and @LeedsHospitals have developed a fix to turn sleep apnoea machines into ventilators.

Estimates indicate thousands of similar devices across the #NHS and rapid modification could significantly increase respiratory support availability

The modification required so the device can be used to treat #COVID19 patients is straightforward and involves changes to the 'NIPPY 3+' device’s settings and re-configuring the supply of oxygen so it flows directly to the face mask worn by the patient.

The machine operates in a mode called CPAP: constant positive airway pressure.  That means the pressure inside the mask is slightly raised, keeping the patient’s airway open and making it easier for them to breathe.  It provides enriched oxygen of between 40 to 60%.

Sleep apnoea is a condition where people stop breathing in their sleep - the machine ensures air supply is maintained.
