The number of patients on trolley's has risen significantly since last year.
The number of patients on trolleys last week is up 190 per cent on the same week last year.
A nurses union's warning of an "extremely serious" overcrowding situation in Irish hospitals.
The Irish Nurses and Midwives Organisation says it's "out of control" in many facilities, and putting patients and staff in danger.
The highest number of people on trolley's in over a year was recorded nationally on Tuesday.
The Mater Hospital in Dublin's now asking people to avoid its emergency department where possible.
Just under 28,000 people attended emergency departments last week, an all time high.
That number is up 46 per cent on the same week last year.
Of those 28,000 attendances, only 25 per cent were admitted.
Naas resident and General Secretary of the Irish Nurses and Midwives Organisation, Phil Ni Sheaghdha, says overcrowding is widespread:
