摘要：
Methods and devices to determine rate of particle production and the size range for the particles produced for an individual are described herein. The device (10) contains a mouthpiece (12), a filter (14), a low resistance one-way valve (16), a particle counter (20) and a computer (30). Optionally, the device also contains a gas flow meter (22). The data obtained using the device can be used to determine if a formulation for reducing particle exhalation should be administered to an individual.
