Online published on 30 April, 2019. Abstract Background The use of equipment such as spirometers in respirometry and analysis of respiratory muscle strength are some of the methods of evaluation for lung volume. Advancement in technologies aims to measure and evaluate the respiratory performance which is Vital for health professionals. The aim of the study find out the correlation of lung volumes between spirometry and the values obtained in AutoCAD® software Methodology The study was Non-experimental design, observationaltype. Total 15 subjects, age group of 18–24 years with no history of respiratory illness were included and subjects using bronchodilator were excludedat SRM Medical College Hospital and Research Centre, SRM Institute of science and technology, Kattankulathur. There wasfive-point mapping for anatomical modeling and photogrammetry with each evaluated for Spiro metricvalues. A video was taken during the procedure and filmed then the film was extracted into images for the proof of maximum inspiration and expiration. With the use of AutoCAD® software the defined respiratory volumes were obtained. Results Statistical analysis shows that correlation between the upper abdomen inspiration the mean and S.D value 116.93±11.8, and the FVC mean and S.D value 2.77±75, FEV1 is 3.96±64 respectively. The correlation is significant at p< 0.05 (2-tailed). Conclusion The study concluded, the FVC and FEV1 lung volumesmaypredict which are co-related with the abdominal inspiration of the 3-dimensionalexploration.
