Software for interpreting pulmonary function
The LungXplorer software is designed to familiarise yourself with real data collected in a normal population. The database comprises
- Some 14,500 longitudinal spirometric measurements (FEV1, FVC) in about 4,500 adults (18-80+ yr). Data were collected in a normal population at 3 year intervals for up to 12 years.
- About 6,200 longitudinal measurements (FEV1, FVC) in about 750 adolescent schoolchildren, who were about 11-12 years old at the start of the study. Data were collected at half year intervals for up to 7 years.
- Associated flow-volume curves
- Anthropometric data
- Respiratory symptoms
- Smoking history
- Predicted values and their lower ‘limits of normal’
- A computer-generated interpretation, employing the ECSC/ERS predicted values.
- Explore the database both cross-sectionally and longitudinally. Data will only be displayed longitudinally if at least two measurements were available within a person. You can come to grips with:
- Variation in the shape of MEFV curves in health and disease, during growth and ageing.
- Interpreting spirometric data, i.e. FEV1, (F)VC and their ratio.
- Expressing spirometric data relative to predicted values.
- Check whether individuals track along predicted values.
