Will beached porpoise Nena survive?

This 6 March 2016 video says about itself:

On the 5th of March 2016 a live stranded harbour porpoise was found on the German coast. She has been admitted in the rehabilitation centre of SOS Dolfijn [in the Netherlands]. Too weak to swim by herself she is being supported day and night. She was found dehydrated and is being given fluid and fish. By a tube the fluid is given to her every several hours. The fish she eats eagerly on her own. That is a good sign!
