Up to 400 people protested today outside Letterkenny General Hospital demanding an urgent increase in acute inpatient hospital beds.
The protest is organised by the Irish Nurses Organisation, which says that 70 beds are needed to solve the current crisis in the hospital.
Nurses say they are pushed to their limits on a daily basis and that patients are being nursed in totally unsuitable conditions in the hospital.
Consultant Dr Brian Hennessy told RTÉ News that the situation in Letterkenny is untenable.
He said that in one week in January alone, 315 people had outpatient appointments cancelled, and in the month of January as a whole, 300 operations were cancelled.
Some of these were cancelled for the fourth time and 50 were major surgeries, including cancer operations.
