Sefton Central Labour MP Bill Esterson quizzed Secretary of State for Health Andrew Lansley about the case of a 79-year-old Maghull constituent who waited 80 minutes in a pool of blood for an ambulance.
Bill raised the case of Pat Taylor and her 81 year old husband Derek in the House of Commons, which was featured in the Liverpool Echo.
Mrs Taylor, who has dementia and osteoporosis, tripped and fell down the stairs at the home she is being cared for on Deyes Lane.
Staff immediately called an ambulance and then husband Derek who raced to the scene from the couple's home in Buckingham Road.
He arrived within minutes to find his wife lying in a pool of blood at the foot of the stairs. Staff were looking after her but were concerned about moving her before the trained ambulance staff had arrived.
With Mrs Taylor drifting in and out of consciousness, a second call was made to the ambulance service 15 minutes after the original call.
It wasn't until another seven minutes - now 47 minutes after the original call - that an ambulance was "allocated to attend the scene".
But this ambulance was then diverted to another incident.
A second ambulance was sent to the scene after 69 minutes - arriving 1 hour 19 minutes after the original call.
Mrs Taylor arrived at hospital two hours seven minutes after the original call.
Bill asked Health Secretary Andrew Lansley: "The Secretary of State told us that every ambulance trust was meeting response, but that is not the experience of one of my constituents. Mrs Taylor waited 80 minutes while lying in a pool of blood for an ambulance. How can he say that every ambulance is reaching their statutory call-out times and can h give us assurances that his re-organisation of the health service is not having an affect on the ambulance service?"
