An elderly woman suffered serious injuries after accidentally setting her clothes on fire with a cigarette, it is believed.
The pensioner was airlifted to Wythenshawe Hospital, which has a serious burns unit, at 6.30pm yesterday after paramedics were called to Hammerton Place on Grange Park.
She was in a 'very poorly' condition, though conscious, a spokesman for the Lancashire Fire and Rescue Service said.
An investigation is now underway to determine the full facts of what happened.
A spokeswoman for the North West Ambulance Service (NWAS) said a 999 call was made at 5.34pm and logged as a 'red two' life-threatening emergency, which paramedics are expected to reach within eight minutes in 75 per cent of cases.
An ambulance arrived on the scene 16 minutes later, at 5.50pm, with a helicopter from the North West Air Ambulance Service called out around 20 minutes after that.
Fire crews - two from Blackpool and one from Bispham - were also called out, at 5.45pm, but found there was no fire to put out, though they did help the paramedics.
An NWAS spokesman said: “The trust apologises for the delay and would like to assure the patient that we did allocate a resource as soon as one became available.
"We were dealing with a number of other incidents within the Blackpool area at the time, including three other ‘red’ priority calls within the same hour."
