Asthma is a chronic lung disease that affects people of all ages. While traditionally, spirometry has been used to study children and adults with asthma, pediatric patients were typically too young to participate. iSonea, a company that develops acoustic respiratory monitoring devices, has recently found a solution to this problem and announced the launch of a post-market study using their WheezoMeter monitoring technology. The study, called Wheeze Rate Correlation and found on clinicaltrails.org is planned for two locations in California.
