What procedure is used by anesthesiologists for treatment of post epidural puncture headache?

They do a blood patch. A little amount of blood is taken from the patient and the anesthesiologist injects the blood at the site of the original puncture. A blood clot is established and it stops the leaking of cerebrospinal fluid. Loss of CSF causes the headache and when the puncture site is patched CSF stops leaking and the headache goes away.

Imma gonna say go with the very first answer (:

Air goes past the epiglottis and into the trachea when you breathe in. from there, it goes to your vocal cords in the larynx until it reaches the bronchi. from the bronchi, air passes into each lung.
