There are 33 patients on trolleys at Mayo University Hospital today - up from 22 yesterday.
The latest figures from the Irish Nurses & Midwives Organisation show 285 patients admitted to hospitals across the country are waiting for beds today - including 33 at Mayo University Hospital, 26 at Sligo University Hospital, 9 at Portiuncla in Ballinasloe and 5 on trolleys at University Hospital Galway.
Meanwhile, Mayo University Hospital has today taken delivery of a long-awaited temporary modular unit, which will provide extra capacity this Winter.
The unit arrived in several sections this morning, and was lifted on-site by a large crane.
It's hoped the modular unit will be fully operational by the end of November.
