Commander Kehar Singh an Octogenarian had also put Dr. Vandana Jain and her team’s creativity to test at Advanced Eye Hospital and Institute at Sanpada, Navi Mumbai. Commander Singh was once an athlete and used to actively compete with Milkha Singh and was crowned Mr. Cochin. He is suffering from a condition called tracheal stenosis where his main airway got extremely narrow. Additionally, his airway would collapse and get blocked whenever he lies down. Cdr. Singh has to resort to a positive airway pressure wherein a machine increases the air pressure in the air passage during sleep thus preventing its collapse. Besides this, he has to sleep on his side as he cannot lie down on his back for more than a few minutes without getting breathless. An emergency tracheostomy (an artificial opening in trachea to get airway assess) was made in 1966 after a road traffic accident to get access to his airway. Subsequently he developed narrowing of the airway and developed difficulty in breathing.
