It happened just after 6.50pm yesterday (Sunday, March 22), when a kitchen fire broke out in the 52-year-old's kitchen in A'Becket Gardens, Salvington.
Firefighters rushed to the scene after the distressed woman heard her smoke alarm and dialled 999. when they arrived, they found smoke billowing from the front door.
Emergency operators had been talking to the woman to give her fire survival guidance, but by the time the crew reached the bungalow she had collapsed in the hallway.
Fire crews wearing breathing apparatus eventually did get inside, and the woman was treated by paramedics. She was later taken to Worthing Hospital where she was treated for smoke inhalation.
Watch commander Ian Spawton, from Worthing Fire Station, said: "The essential value of having smoke alarms fitted throughout the bungalow certainly prevented this incident from having a far worse outcome."
It is not yet known what caused the blaze.
