Coast Guard rescue crews medically evacuated a 70-year-old woman in Provincetown Harbor, Massachusetts, Friday.
Watchstanders at Sector Southeastern New England received notification at 9:06 p.m. from the woman's husband that she was bleeding uncontrollably from her mouth.
A Station Provincetown crew was training nearby aboard a 29-foot response boat small and diverted to assist.
The rescue crew took the woman aboard and transported awaiting EMS at the Provincetown Harbor Pier.
"We train constantly for at-sea medical emergencies," said Petty Officer 1st Class Andrew Stokes, a watchstander at Sector Southeastern New England.
He said because the crew was already in the area, they were on scene immediately and able to transfer care quickly.
