Hand‑held mechanical peak expiratory flow (PEF) meter for routine monitoring of peak expiratory flow during forced expiration. The device shows PEF on a calibrated analogue scale to give immediate, visual readings in litres per minute, and is intended for repeated use by the same patient following an appropriate user guide. User guidance describes a simple home monitoring routine (three blows per session, record the highest result, typically twice daily) and promotes maintaining a peak flow diary to track day‑to‑day variation and visualise trends over time.
