Respira wants to monitor your lung health with a wearable device – TechCrunch





Over the years, we’ve seen portable devices measure every aspect of your body, but lung capacity is more esoteric than most. Sylvee is a brand new wearable device from Respira Labs that continuously measures lung function – perfect for patients with COPD and asthma, and others who may have temporarily reduced lung function. We are thinking in particular of a certain pandemic which affects lung function.

Sylvee is a product that is worn in the lower part of the rib cage, and it promises to easily and continuously assess lung function without having to blow anything. The portable patch has built-in speakers and microphones that measure changes in acoustic resonance. The company says this is a good indicator of changes in lung air volume, which is the basis of lung function tests.

The technology is incredibly smart. Sylvee generates noise through its speakers, then uses the microphones to measure the sounds generated. The theory is that if there are air cavities, it changes the quality of the sound, much like hitting a drumhead on a drum kit, before filling the drum with cotton, wool or liquid. and do the same. Obviously these are lungs – I’m not a doctor, but I have to assume that there are usually air chambers in there. The laptop uses the data it collects to measure lung volume, capacity, flow, and trapped air.

“Well-established science shows that air entrapment can be measured with over 90% accuracy using low frequency sound. There is a marked difference in the acoustic resonance spectra of COPD patients compared to healthy controls, ”explained Dr Maria Artunduaga, Founder and CEO of Respira Lab. “With over 100 million Americans affected by COPD, COVID-19 and asthma, and with an aging population, it can be lifesaving to remotely and accurately monitor lung function and find a problem early enough. to avoid serious consequences. Our goal is to report abnormalities at an early stage, enable earlier treatment at home, and empower patients to manage their own health. “

The product – Sylvee – is named after Artunduaga’s grandmother, who suffered from COPD and died after symptoms rapidly worsened without detection.

“The device facilitates early diagnosis and management of acute deterioration, which respiratory patients should avoid. We provide vital information to doctors and patients so they can change their medical treatment sooner and avoid hospitalizations, said Dr Artunduaga. “This is what happened with my grandmother. She suffered from COPD and had a sudden exacerbation of her symptoms and tragically died. I quit my medical career and devoted myself to conceiving the Sylvee because of this terrible and common result.

Respira Labs has set itself the goal of achieving 90% accuracy in measuring air entrapment by continuing a large-scale trial on more than 500 patients located in the United States and abroad. They also plan to publish in top journals by the end of 2022. The device is currently in prototype, with FDA clearance expected in the next 18 months.
