In 1846, London surgeon John Hutchinson invented the spirometer, a thing you blow hard into, to measure the volume of air inspired and expired by the lungs. It’s a pretty basic idea. Incredibly, since then, the technology has barely evolved. Today, the modern spirometer doesn’t even measure the amount of CO2 expelled by the lungs, a crucial data point for assessing chronic obstructive pulmonary disease (COPD).
Now a Cambridge, UK startup has come up with a radical new technology device that, it claims, is affordable, portable, requires minimal training, and also measures CO2.
