General
By measuring FEV1, as well as peak flow, the asma-1 gives a clearer picture of lung health. The asma-1 stores up to 600 test sessions and automatically assesses test quality.
- Simple to use
- Electronic record – no need for record cards
- Automatically assesses test quality
- More accurate than a mechanical meter
- Patient can review past results at home
- Measures PEF and FEV₁
- Child version measures PEF, FEV₁, FEV₀.₅ and FEV₀.₇₅
- FEV₁ has less diurnal variability and is less effort dependent
- Can display % of personal best for both PEF and FEV₁
- PEF and FEV₁ zones can be personalised
- Automatically stores best values
- Large, easy to read display
- Stores 600 test sessions
- Suitable for use in clinic with SafeTway® mouthpieces
- Easy to clean mouthpiece and flowhead
- Language independent
- ISO 23747:2007 Peak Flow Meters ATS/ERS: 2005 Spirometry Guidelines ISO 26782:2009 Spirometers
