U.K., April 14 -- It is estimated that sleep apnoea affects about 1 billion people worldwide, with some research suggesting it is experienced by over 50% of the population in some countries.

The condition is hard to diagnose, as sleep tests are complex and require overnight stays in labs and for the patient to be connected to devices via lots of wires. This is also the case with polysomnography, considered the gold standard for obstructive sleep apnoea diagnostics. It requires specialised personnel to prepare the patient, who is either hospitalised overnight, or sent home equipped with bulky equipment that often disrupts sleep. It is also time-consuming and complex to interpret the data, leading to delays in diagnosis.
