Empowering respiratory health monitoring — anytime, anywhere.
Respiratory diseases such as Asthma, COPD, and Pulmonary Fibrosis are among the top 10 leading causes of death in Sri Lanka. In 2020 alone, Asthma-related deaths in Sri Lanka reached 6,471, accounting for 5.57% of total deaths. Despite the critical need for respiratory monitoring, digital spirometers are rare, expensive, and confined to premium healthcare facilities.
Most government hospitals still rely on outdated manual spirometers — they’re bulky, less accurate, and not user-friendly. There is a clear gap in accessible, accurate, and portable respiratory monitoring tools.
To develop an affordable, portable, and easy-to-use smart digital spirometer that allows individuals — whether patients, athletes, or health-conscious users — to monitor lung function anytime, anywhere, and share data easily with medical professionals.
We designed a Smart Portable Spirometer that offers:
- 📱 Real-time feedback via a connected mobile app
- 📊 Accurate readings personalized by age, gender, height, weight, and race
- 🧠 Automatic computation of critical respiratory parameters:
- FVC (Forced Vital Capacity)
- FEV1 (Forced Expiratory Volume in 1 second)
- FEV1/FVC Ratio
- 📈 Historical tracking and visual reports
- 🌐 Data sharing with doctors via the app
- User blows air into the device.
- The airflow passes through a tube where a velocity sensor captures the flow speed.
- Using the equation
Q = A × V(Flow rate = Area × Velocity), we calculate the flow rate. - The app processes this to compute:
- FVC
- FEV1
- FEV1/FVC ratio
- Data is displayed and stored in the app for user review or sharing.
💡 We used a special tube design to maintain consistent velocity across the section for more reliable readings.
- Real-time spirometry readings
- Lung function history and trends
- Report generation
- Data export & doctor sharing functionality
- Individuals with Asthma, COPD, or Pulmonary Fibrosis
- Athletes monitoring respiratory performance
- Singers and wind instrument players optimizing lung capacity
- General users interested in proactive lung health management
