Introduction: Nebulizers have been used for many years in acute and chronic management of airflow obstruction in adults and children. Although nebulisation is prescribed by the clinician, paramedics play a critical role in administering treatment to the patient. It has been observed that longer nebulisation time causes inconvenience resulting in reduced patient compliance. Aim: To assess the awareness and knowledge amongst the nursing staff of a tertiary care centre with regard the nebulised method of inhalational drug delivery pre and post educational session. Materials and Methods: Questionnaire based cross sectional study of 320 candidates pre and post educational session. Results: Significant improvement in the knowledge regarding the appropriate techniques of nebulisation including the disinfection, amount of medication to be used in the chamber, duration for which the nebulisation has to be given, etc. Conclusion: All the scores showed positive change indicating improvement post educational programme.
