A nurse working at Our Lady's Children's Hospital in Crumlin lay dead for two days in a room used by parents.
Efforts were made to resuscitate her, but sadly she was pronounced dead at the scene.
A garda investigation is now underway following the shocking discovery on Tuesday morning, however, the Irish Independent reports that the death is being treated as a tragedy.
It is also being reported that the woman turned up for work as normal on Sunday.
The room where she was found can be used by parents whose children are receiving treatment at the Dublin hospital.
A Crumlin spokeswoman told the Irish Independent: "Our thoughts, prayers and deepest condolences go out to the staff member's family and friends and colleagues here at Our Ladys's Hospital.
"The hospital will be making no further comment as it is the subject of a garda investigation."
