There are 650 Covid-19 patients receiving some level of critical care across the country.
HSE CEO Paul Reid has warned of a 'critical' virus situation in Irish hospitals.
Reid said that there are 214 people in intensive care units and 436 receiving advanced respiratory support.
In a tweet posted on Sunday morning, he said that teams are "battling to hold the levels of care that we value" and "to save lives".
He said: "It's not an Emergency Department crisis now but it's probably more critical than that."
As of Sunday morning, there are 1,914 people hospitalised with Covid, with 80 patients admitted and 47 discharged since yesterday.
This comes after Ireland reported 77 further Covid-19 deaths on Saturday, as well as 1,910 new cases.
Speaking of these figures, Chief Medical Officer Tony Holohan said: "Through the solidarity shown by families and communities across the country in recent weeks, we are beginning to flatten the curve of Covid-19 infection.
"We can only continue this by continuing to stay at home and avoid meeting or mixing with others in our social circle, including for any close family gatherings, such as birthdays or funerals, as these can be ‘super-spreader’ events.
"We know it is possible to have Covid-19 without displaying symptoms, so we all need to behave as though we are infectious and minimise our close contacts with others.
"If you suspect that you might be ill, isolate away from others in your household, let your close contacts know and come forward for testing as soon as possible."
