Asthma Management System
Introduction
• What is Asthma? – Restricted airways
– Intrinsic vs. extrinsic
– Track via PEF and FEV readings • (e.g. via Peak Flow meter)
Introduction• What products exist already?
– Most show personal red/yellow/green zones – Most chart recent FEV/PEF readings – Some allow auto-loading of FEV/PEF values; very few
allow both manual and auto-loading of FEV/PEF values
– Few allow data manipulation– Few are portable– Few allow users to record/track asthma-attack info– Few track the presence of current or past triggers (e.g.
pollen counts, temperature, humidity, other personal triggers)
Introduction
• Goals for AccuLung System– Provide a mobile resource for tracking asthma symptoms and
history.– Provide a graphical view of user’s asthma history.– Track environmental conditions related to asthma triggers.– Help prevent imminent asthma attacks.
• Application Requirements for AccuLung– PDA with color display– Wireless capabilities– Digital Peak Flow Meter with IR port
Methodology
• Researched existing products; ordered one • Interviewed asthmatics for design ideas• Designers created own designs• Conglomerated all these ideas into one master design• Implemented system• Performed usability tests with asthmatics• Changed design based on feedback • Received critique from professor and fellow classmates• Changed design based on feedback • Created website and project paper
Usability Procedure• Users:
– 4 asthmatics and 5 non-asthmatics
• Tasks: – Set up a patient profile – Record data from a Peak Expiratory Flow test – Check recent test result trends – graph results - compare– Save History, medications list and other information– View current environmental conditions
• Pollen Count• Temperature• Humidity• Air Quality Index
Usability Findings
• Choose meaningful colors for navigation buttons and environment readings
• Environment button is hard to locate• Empty ‘Enter Manually’ input box crashes the system
– Plus designers found some input boxes (FEV, PEF) misleading• PEF/FEV graph values are too small to read;
– Also add ‘Export’ button to PEF/FEV graph page• Add ‘personal best’ to home page’s PEF/FEV graph
Future Plans
• Show more values on the same graph as PEF/FEV values:– Environmental Triggers
– Medications
• Multiple user tracking
• Record asthma triggers
• Develop physician version
