MobAsthma monitors the asthma condition of the patients and their exposure to pollution. A peak flow meter and a pollution sensor are interfaced to the mobile phone via a Bluetooth connection, and measure both the volume of air inhaled and expired by the patients as well as the airborne particle concentration. These measurements are coupled with the patients’ location and made available to allergists and asthma specialists to investigate the personal relationships between asthma attacks and exposure to air pollution. In addition to investigation purposes, MobAsthma can detect asthma attacks in early stages and autonomously alert remote medical staff.
