On Wednesday, a former executive-on-call at the hospital sobbed when she was asked if Aoife’s death impacted her.
Two framed photos of Aoife have been placed at the top of the courtroom.
Her family, including her parents and sisters as well as her friends, sat together throughout the different witness testimony.
They have said that no other person should suffer like Aoife and that they are “haunted” by her loss.
The court was also told that her family donated some of her organs following her tragic death.
Senior counsel Damien Tansey for the family described how on the night the teenager was admitted the family was “screaming and roaring” for help.
He said that the family understands Aoife’s death was not intentional, but they want answers.
Medical staff said that, as a category two patient, she should have been seen within 10 to 15 minutes and received antibiotics.
The court was also told that the blood tests taken from Aoife showed she was amenable to all antibiotics and there is nearly a 100% chance of mortality if sepsis is not treated quickly.
As Aoife’s sister left the inquest, Coroner John McNamara said the courtroom could take a few minutes’ break and that Ms Steed could step down if she wished.
After composing herself, Ms Steed outlined what steps she took when she received a phone call from nurse Patricia Donovan who described earlier a “major emergency” in the emergency department.
Ms Steed said: “I called the [UHL] clinical director ... I escalated it.”
