When a care givers has knowledge about easy & home management of chronic obstructive pulmonary disease, quality of life of the patient is enhanced but lack of knowledge of the care giver can causes unnecessary suffering to the patient. Objective: 1. To assess the knowledge of caregivers in COPD patients regarding Postural Drainage.2To develop the Video Demonstration module on Postural Drainage among the caregivers in COPD patients.3. To re-assess the knowledge caregivers in COPD patients regarding Postural Drainage 4. To find out the effectiveness of Video demonstration Module on postural drainage among the caregivers of COPD. 5. To find out the association between the knowledge score with selected demographical variables of caregivers in COPD patients. Research Methodology: Research approach is an umbrella that covers the basic procedure for conducting the study. In this study evaluative research approach was used & Research design of pre experimental in one group pre test Post test design was selected. The study was conducted in Maheshwari Hospital, Gwalior & 40 caregivers of COPD patient was selected by the Purposive sampling technique. The caregivers COPD was used who have age 25 to 50 years & work in the COPD patients of Maheshwari Hospital, Gwalior. Result: The caregiver of COPD in pre test knowledge score that 72.5 were inadequate knowledge, 27.5% were Moderate knowledge & none of the participants have adequate knowledge but after the video demonstration the post assessment knowledge score highly no. 80% of the participants have moderate knowledge, 12.5% have inadequate knowledge & remaining 7.5% participants have adequate knowledge. The Pre test Mean±S.D. 9.86±4.95, Mean score % 32.86% but Post test Mean±S.D. 15.06±5.23 & Mean score % 50.19%. The enhancement of Mean±S.D. 5.2±0.7, Mean Score % 17.32%, paired “t” test value 16.8 & degree of freedom 39 at the level of significance 0.05. This result also proof that the video demonstration are very effective & enthusiasm to increase the level of knowledge. The association of chi square with their selected demographic variables & Post test knowledge score that Education qualification, Residence area & Source of information regarding postural drainage among the caregiver of the COPD patient’s were significant and other socio demographic variables such as Age (Year’s) & monthly income of the family member’s (RS) were not significant at P< 0.05 level of significant.
