The purpose of the study was to evaluate the effectiveness of balloon blowing exercise among children with age group of 5 to 15 years who were attended in out patient department and admitted in pediatric ward, MAPIMS at Melmaruvathur. A pre experimental design was used, total 30 children were selected by using purposive sampling technique and exercise was given for two weeks period and post test was done on 4th and 16th day. The mean, standard deviation, paired “t” test and chi –square were used to analyses the data. the result of the study stated that the pre intervention mean values was 27.0 with standard deviation 4.61 and in post test I the mean value was 22.2 with standard deviation 5.78 and in post test II the mean value was 16.2 with standard deviation is about 0.752. The calculated t value is 6.467 in post test I and 10.09 in post test II, is more than the critical t value, which is 2.042 at p<0.05 level. There was a significant improvement of respiratory patterns among children with bronchial asthma by using balloon blowing exercise. Hence, the post test II score is more comparable rate than post test I score. The conclusion of the study shows that the balloon blowing exercise has positive effect on respiratory patterns.
