The Mini-Wright measures the maximum flow rate in a forced exhalation- known as the peak expiratory flow (P.E.F.). After determining a patient's best P.E.F. with his/her physician, the patient self-tests daily as instructed by the physician and records the highest readings on a daily trend chart. These meters come with a PF-375 sterilizable mouthpiece with universal tapered design for both adult and pediatric use.

Conforms to the 1991 recommended technical standards by the National Asthma Education Program (NAEP), National Heart, Lung, and Blood Institute (NHLBI); and is based on American Thoracic Society (ATS) Waveform 24.

Note: Children 6 years and younger, or those with excessive lung damage, should use the PF-440x low-range meter.

The AFS Low-range Mini-Wright incorporates the Aerodynamic Flow System (AFS) to bring accuracy and consistency to patients with lower peak flow requirements.
This new, smaller Mini-Wright is specifically designed for younger patients. The scale is clear and easy to read.
