"The response shown to the treatment continues to be minimal by all the vital organs and his heart rate and blood pressure continue to be low and supported by drugs," A N Safaya, director, Sri Sathya Sai Institute of Higher Medical Sciences said in a medical bulletin in Puttaparthi.
There is no significant change in his overall clinical condition since Thursday. The doctors, however, are continuing round-the-clock treatment of 86-year-old Sai Baba, Safaya said.
Sai Baba was hospitalised on March 28 following problems related to heart and respiration.
As a precautionary measure, the state government has deployed additional police forces in Anantapur district particularly Puttaparthi town to maintain law and order.
