According to the Vatican, the 88-year-old Argentine has received large amounts of oxygen and even blood transfusions, since samples have shown that his health condition can be linked to anemia.
Doctors have previously stated that the Pope suffers from double -sided pneumonia and trachea. But the great danger according to the doctors is that he should suffer from sepsis as a result of pneumonia.
On Friday, there were no signs of sepsis and the Pope reacted positively to the treatment he received, according to a hospital bulletin. But on Saturday morning, the Pope must have shown asthma -like respiratory problems.
Francis has been cared for at the Gemelli hospital in Rome since February 14.
