Background: Children of all ages may be diagnosed with acute infections of the lower respiratory tract. It renders to occur mostly in younger children. Childhood respiratory problems include asthma, bronchitis and pneumonia. It is believed that breathing exercises strengthen the lung capacity and maintain a normal breathing pattern. Objectives: The objectives of the study were to assess the respiratory parameter of children with LRTI before & after strelnikova breathing exercises and secondly to determine the effect of strelnikova breathing exercises. Material & Method: Quasiexperimental research design was used for strelnikova breathing exercises on respiratory parameters of children with LRTI admitted in the pediatric ward at IMS & Sum Hospital, Bhubaneswar. The nonprobability purposive sampling method was being used to choose 60sample. The Procedure was showed to the experimental group for 10 - 15 minutes for five days and was given twice in a day. There was no intervention for the control group. The study was conducted for one month .patients of both gender of age group 5-12 year selected and critically ill with ventilator patients was excluded. Result & conclusion: Data were analyzed by using descriptive and inferential statistics. The findings for post-test was obtained in experimental & control group were respiratory rate (t58=9.50, p<0.0001), breath sounds (t=582.21, p<0.03), &oxygen saturations (t58=5.99, p<0.0001) respectively which was statistically significant in respiratory parameters. The pretest and posttest findings were for respiratory rate ( t29=1.21, p>0.23),breath sounds (t29=0.36 ,p>0.71),& oxygen saturation (t29=3.06,p<0.004) which was statistically not significant .
