Neelam Babbar a 56 year female was suffering from a rare disease in which there was a large collection of abnormal proteinaceous material in her lungs, a condition called Pulmonary Alveolar Proteinosis. This abnormal protein collection had led to severe lung dysfunction and she was in severe respiratory distress with very low oxygen concentration in her blood. She had to be ventilated and had very little chance of survival. She was managed by the Pulmonlogy and Critical Care Teams at Fortis Memorial Research Institute. Dr Manoj K Goel, Director, Deptt. of Pulmonology, Sleep and Pulmonary Critical Care did washing of her both the lungs with more than 20 litre of saline, a procedure called whole lung lavage. This procedure resulted in removal of this abnormal protein from her lungs and her life could be saved. She is now breathing normally with good oxygen saturation in her blood.
