Francis is getting ready to spend the night in the Gemelli Hospital.
His oxygen saturation levels are fine, and he has had the necessary tests to rule out more serious problems, medical sources said.
Francis went to Rome’s Gemelli Hospital Wednesday afternoon for “some tests which had been scheduled previously,” according to Vatican spokesman Matteo Bruni.
Vatican sources said Francis may spend a few days in hospital, after his security detail was stationed there at least for the night.
His audiences scheduled for Thursday and Friday have been cancelled.
Sources said he had no heart problems and that respiratory exams had been carried out.
His overall health condition does not arouse any concern, they said.
The pope, 86, has knee problems which have forced him to often use a wheelchair.
He has said he might resign like his predecessor Benedict XVI if bad health makes it impossible for him to continue doing his job.
In December, Francis revealed that he has signed a letter of resignation to be used if he is unable to perform his duties for health reasons.
