I was on break when noticed an FA (Flight Attendant) being assisted by another FA to sit in empty seat next to my break seat. FA was administering First Aid. I asked another FA to wake the Purser; get medical personnel [to] use the same MEDlink procedures as we do for customers. I went back to flight deck early to coordinate with Dispatch and MEDlink. Unable to contact Dispatch over the pole due to out of Imarsat area and inoperative Iridium. Finally contacted Dispatch via ACARS and advised.
