Should patients with panic attacks rebreathe the same air by using a paper bag?

A patient I recently saw told me about how, in the past, she had severe panic attacks for which she was made to rebreathe into a paper bag. Maybe, like me, you were taught about this during your training.

Should rebreathing into a paper bag be used if a patient has a panic attack along with hyperventilation-related symptoms in our offices or at home?
