In the latest update to the iOS 8 beta, Apple added a number of health-related features including a data tracking capability for spirometry. Spirometry is the most common of the pulmonary function tests (PFTs), measuring lung function, specifically the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD.
Apple announced its Health app and HealthKit developer package at its WWDC event in June. The app will allow users to store the data from any number of health and fitness tracking devices in a single app that will come preloaded on future Apple mobile devices. From there it could potentially, with users’ permission, make that data available to their doctor or hospital.
