Back in 1846, a London surgeon named John Hutchinson created the spirometer, which is commonly used by doctors to assess lung function in asthma patients by measuring the amount of air inhaled and exhaled. Surprisingly, this technology has seen little advancement since its inception.

Spirometers face challenges when patients vary the force of their blowing, making it difficult to obtain consistent results.They also struggle to differentiate between various respiratory conditions and their severity. However, a company based in Cambridge has developed a handheld medical device called N-Tidal that addresses these limitations. N-Tidal can sensitively detect changes in lung function, leading to faster, more precise, and automated diagnosis of chronic obstructive pulmonary disease (COPD). Additionally, the company plans to incorporate the capability to measure asthma issues into their product roadmap.
