The Vitalograph asma-1 is a simple home use electronic respiratory monitor that measures PEF and FEV1 and may be integrated with smart phone or tablet for ePRO data collection. It offers greater accuracy than mechanical peak flow meters and eliminates the need for paper record cards.

• Measures PEF and FEV1
• FEV1 has less diurnal variability and is less effort dependent than PEF
• Displays % of personal best for both PEF and FEV1
• PEF and FEV1 zones can be personalised
• Automatically assesses test quality
• Automatically stores best values
• Large, easy to read display
• Stores 600 test sessions
• Suitable for use in clinic with SafeTway mouthpieces
• Uses long life AAA batteries
• Easy to clean mouthpiece and flowhead
• Language independent
