The family of Paula Triscaro filed the lawsuit in the Cuyahoga County Court of Common Pleas, accusing the three paramedics of disregarding their duty to save the 55-year-old woman during a 2007 ambulance run.
Triscaro's lawyers also alleged the paramedics and fire department tried to cover up what happened after the family began investigating.
Attorneys representing Bainbridge Township and the paramedics had previously denied any wrongdoing, saying the "paramedics were, at all times, acting appropriately to save Paula Triscaro's life."
Court personnel today confirmed the two sides have reached a preliminary settlement, but said terms of the deal were confidential.
Attorney Charles Kampinski, who represented the family, declined to comment on the settlement. A call to the attorney representing the township was not returned.
Triscaro first began experiencing chest pains and vomiting on the night of Oct. 5, 2007. A friend dialed 9-1-1, and Bainbridge Township emergency medical service workers were at Triscaro's home when she went into cardiac arrest.
For the next 58 minutes, Triscaro stopped breathing.
Doctors at Solon Medical Center revived Triscaro, but the lack of oxygen caused permanent brain damage and left her helpless.
Kampinski told The Investigator Tom Meyer that the tragedy could have easily been prevented if paramedics had shocked her heart, using a defibrillator that was hooked up to her and monitoring her heart.
"Had they done what they should have done that night, Paula Triscaro would be fine," Kampinski said last month.
Kampinski also accused the department of orchestrating a cover-up to hide their negligence once the case became public.
Channel 3 News reviewed the written report paramedic Michael Overholt filled out after the ambulance run, as well as his testimony taken months later in a deposition for the Triscaro's lawsuit.
In his written report, Overholt said Triscaro's heart was in "V-Tach." That's an irregular heart rate that can be shocked back into rhythm with a defibrillator.
But in his deposition, Overholt said Triscaro's heart rate was changing before it settled into "asystole," meaning her heart stopped beating and could not be shocked.
In addition, Overholt said neither he nor a fellow paramedic had time in the nine-minute run to the Solon Medical Center to administer drugs that may have restarted Triscaro's heart.
There was also incriminating testimony from both a hospital dispatcher and a doctor.
"In the emergency room, they were told she had a shockable rhythm and they were told she had a shockable rhythm by EMS," Kampinski said.
