A teenage girl died from meningitis after spending up to 16 hours on a hospital trolley.
Aoife Johnston, 16, was admitted to University Hospital Limerick last week suffering with the bacterial infection and despite eventually being prescribed antibiotics she deteriorated beyond recovery.
The hospital has said it will conduct an investigation.
Tributes have been left in an online book of condolences to the teenager, from Cronan Lawn, Shannon, Co Clare, who died on Monday.
A poignant refrain from an “anon” read: “Rest In Peace beautiful angel. Fly high.”
Ms Johnston is survived by her “heartbroken" family, parents James and Carol, sisters Meagan and Kate, and her grandparents.
Her funeral mass took place at 11am on Thursday followed by burial in Illaunmanagh Cemetery.

The Department of Public Health Mid-West said it was “investigating a single case of confirmed meningococcal disease in Clare”.
Toiseach Leo Varadkar has said he wants a swift inquiry and has contacted the HSE, reports the Irish Mirror.
He wants the probe to determine if Aoife's death was preventable.
The Taoiseach said the teenager's family has a right to expect a quick inquiry, adding: “It’s just devastating for the family, particularly at this time of year, and I want to express my condolences to Aoife’s family and friends, and of course to anyone who knew her.”
The Department of Public Health Mid-West went on to say: “We offer our sincere condolences to the family and friends of the deceased.
“Close contacts are being identified by Public Health Mid-West and are being contacted and offered treatment.”
It stressed that “the overall risk to the wider community is considered low”, but that meningitis “is a serious illness involving inflammation of the membranes covering the brain and spinal cord, and it can be caused by a variety of different germs, mainly bacteria and viruses”.
“Person-to-person spread of meningococcal disease is very unusual, especially with others who are not a household or physically close personal contact.”
“Bacterial meningitis is less common but usually more serious than viral meningitis and requires urgent treatment with antibiotics.”
“Bacterial meningitis may be accompanied by septicaemia (blood poisoning). The bacteria live naturally in the nose and throat of normal healthy persons without causing illness.”
“The spread of the bacteria is caused by droplets from the nose and mouth.”
The Department said that the illness occurs “most frequently in young children and adolescents, usually as isolated cases”.
It advised: “Bacterial meningitis or septicaemia requires urgent antibiotic treatment.”
“While the risk to the wider community is considered low, we do want the general public to be aware of the signs and symptoms of this disease.”
Signs and symptoms may include severe headaches, fever, vomiting, drowsiness, discomfort form bright light, neck stiffness, rash.
“We advise that if anyone has concerns, they should contact their GP immediately and ensure that medical expertise is sought,” it said.
The Department said that Meningococcal B disease is “prevented by vaccination”.
“The MenB vaccine was introduced in Ireland for all children born on or after 1 October 2016 because children under one year are at the highest risk of meningococcal B disease.”
“All children are offered MenB vaccine at 2 and 4 months of age with a booster dose of MenB vaccine given at 12 months.”
“First year students in secondary school are offered Men ACWY vaccine.”
