Gujral, 93, was admitted to the Medicity Medanta Hospital here with a lung infection on Nov 19, and is still on the ventilator.
"He is very critical, medicines are not showing much effect, good wishes can help him better," a senior medical consultant, who did not wish to be named, told IANS.
Another senior consultant at the hospital termed Gujral's condition "critical but stable".
"The condition of the former prime minister is critical but stable and changing minute by minute," admitted the consultant, also speaking on the condition of anonymity.
A team of nine senior consultants headed by Dr. Naresh Trehan is keeping a close watch on the patient, he added.
