The U.S. Food and Drug Administration (FDA) has cleared the approval of “Air Next” for people with chronic obstructive pulmonary disease (COPD), asthma or cystic fibrosis.
The device is connected to iOS or Android smartphones via Bluetooth Low Energy (LE) to conduct forced vital lung capacity and forced expiratory volume tests at the same time.
The readings can be collected on your smartphone, which can be shared with a medical professional.
