Rome:Pope Francis was in critical condition Saturday after he suffered a prolonged asthmatic respiratory crisis while being treated for pneumonia and a complex lung infection, the Vatican said.
The 88-year-old pope, who remains conscious, received "high flows" of oxygen to help him breathe. He also received blood transfusions after tests showed low counts of platelets, which are needed for clotting, the Vatican said in a late update.
"The Holy Father's condition continues to be critical, therefore, as explained yesterday (Friday), the pope is not out of danger," the statement said. It was the first time "critical" had been used in a written statement to describe Francis' condition since he was hospitalised on Feb. 14.
The statement also said that the pontiff "continues to be alert and spent the day in an armchair although in more pain than yesterday." Doctors declined to offer a prognosis, saying it was "reserved."
Doctors have said Francis' condition is touch-and-go, given his age, fragility and pre-existing lung disease.
Doctors warn of the possible onset of sepsis
They have warned that the main threat facing Francis would be the onset of sepsis, a serious infection of the blood that can occur as a complication of pneumonia. As of Friday, there was no evidence of any sepsis, and Francis was responding to the various drugs he is taking, the pope's medical team said in their first in-depth update on the pope's condition.
Saturday's blood tests showed that he had developed a low platelet count, a condition called platelopenia or thrombocytopenia. Platelets are cell-like fragments that circulate in the blood and help form blood clots to stop bleeding or help wounds heal. Low platelet counts can be caused by a number of things, including side effects from medicines or infections, according to the U.S. National Institutes of Health.
Francis, who has chronic lung disease and is prone to bronchitis in winter, was admitted to Gemelli hospital on Feb. 14 after a weeklong bout of bronchitis worsened.
Doctors first diagnosed the complex viral, bacterial and fungal respiratory tract infection and then the onset of pneumonia in both lungs. They prescribed "absolute rest" and a combination of cortisone and antibiotics, along with supplemental oxygen when he needed it. Saturday's update marked the first time the Vatican has referred to Francis suffering an "asthmatic respiratory crisis of prolonged magnitude, which also required the application of oxygen at high flows."
Dr. Sergio Alfieri, the head of medicine and surgery at Rome's Gemelli hospital, said Friday that the biggest threat facing Francis was that some of the germs that are currently located in his respiratory system pass into the bloodstream, causing sepsis. Sepsis can lead to organ failure and death.
"Sepsis, with his respiratory problems and his age, would be really difficult to get out of," Alfieri told a news conference Friday at Gemelli. "The English say 'knock on wood,' we say 'touch iron.' Everyone touch what they want," he said as he tapped the microphone. "But this is the real risk in these cases: that these germs pass to the bloodstream."
"He knows he's in danger," Alfieri added. "And he told us to convey that."
