Introduction: The trillions of cells in the body require an abundant and continuous supply of oxygen to carry out their vital functions. We cannot “do without oxygen” for even a little while, as we can without food or water.1 Our body needs a constant supply of oxygen to support metabolism. Without oxygen we can’t live for more than a few minutes. The respiratory system brings oxygen through the airway through the lungs into the alveoli, where it diffuses into the blood for transport to the tissues. This process is so vital, that any difficulty in breathing is experience as a threat to life itself. People with respiratory disorder are often anxious and fearful that they may die, perhaps agonizingly. Chest physiotherapy is a well proven effective therapy for people in improving breathlessness, exercise tolerance and quality of life.6 Background: It is estimated that 235 million people suffer from asthma, more than 200 million people have chronic obstructive pulmonary disease (COPD), 65 million endure moderate-to-severe COPD, 1–6% of the adult population (more than 100 million people) experience sleep disordered breathing, 8.7 million people develop tuberculosis (TB) annually, millions live with pulmonary hypertension and more than 50 million people struggle with occupational lung diseases, totaling more than 1 billion persons suffering from chronic respiratory conditions. Chest physiotherapy is a well proven effective therapy for people in improving breathlessness, exercise tolerance and quality of life. Objective: 1) To assess the pre-test knowledge and practice score regarding Chest Physiotherapy among staff nurses in experimental and control group. 2. To assess the post-test knowledge and practice score regarding Chest Physiotherapy among staff nurses in experimental and control group. 3. To compare the pre-test, post-test knowledge and practice score regarding Chest Physiotherapy among staff nurses in experimental and control group. 4. To associate the knowledge and practice score with selected demographic variable in experimental and control group. Materials and methods: A experimental study with Quasi Experimental Non-Randomized Control Group Design. is used among 60 staff nurses in selected hospitals of the city. The non-probability purposive random sampling technique is used. The collected data was tabulated and analyzed appropriate statistical methods wherever required. Results: The study reveals, in experimental group mean difference of knowledge score was 9.23 and in control group was 0.16. and calculated t-value for knowledge is 15.51 which is greater than table value. In experimental group mean difference of practice score was 10.23 and in control group was 0.16. and calculated t-value for practice is 16.71 which is higher than table value. Hence, H0 is rejected and H1 is accepted. Conclusion: Planned teaching programmed on chest physiotherapy among staff nurses in the experimental group was effective and there is significant increase in knowledge and practice regarding chest physiotherapy among staff nurses in experimental group than in control group.
