Abstract              Background: Patients who developed respiratory failure had to be put on invasive mechanical ventilation in spite of known impending severe complications. Recently, physicians are using non-invasive ventilation for patients with respiratory failure of varied etiology. Aim: To study the indications for invasive and non-invasive mechanical ventilator in patients of respiratory failure. Material and Methods: A total of 216 critically ill Patients admitted in intensive respiratory care unit (IRCU) who developed respiratory failure due to various conditions and diseases were studied for the indications of invasive and non invasive ventilations. Results: Amongst 216 patients, 182 (84.2%) required invasive and 34 (15.7%) required noninvasive ventilator. Out of 182 with invasive ventilator, 138 (75.8%) were of acute respiratory failure (poisoning, ARDS, snake bite). Common indications of noninvasive ventilator was COPD (81%) followed by bronchial asthma (80%). Conclusion: Invasive mechanical ventilation is more commonly used in acute respiratory failure patients including poisoning (organophosphate and related compound), ARDS and snake bite (neuroparalytic), whereas, noninvasive mechanical ventilation is commonly used in patients of acute exacerbation of COPD and bronchial asthma.

Key Words: Respiratory failure, mechanical ventilation, invasive ventilator, non invasive ventilator, indications.
