"Northwick Park Hospital is one of a group of hospitals chosen to care for coronavirus patients".
A hospital in London briefly declared a "critical incident" on Friday due to shortage of intensive care beds caused by a rise in the number of patients with COVID-19, the disease caused by coronavirus, British media reported on Friday.
According to reports, a message sent out to staff said Northwick Park Hospital in Harrow had no capacity left in its ICU.
On March 6, in a letter seen by the Times from Dr Martin Kuper, the medical director told staff: "We are writing to let you know that here at Northwick Park Hospital we are now treating patients with a respiratory illness known as novel coronavirus or COVID-19.
This means that we now do not have enough space for patients requiring critical care", it added.
They added: "Critical care capacity for patients with coronavirus is being organised on a cross-London basis so that hospitals and organisations work together to deliver the best possible care for patients and that is what has happened in this case".
"This kind of coordinated, flexible response is one of the NHS's strengths but with staff pulling out all the stops they need the public to play their part too, by following the expert guidance on washing your hands, staying at home and using health services responsibly".
The hospital is run by London North West University Healthcare Trust, which has since reported six deaths related to coronavirus, all at Northwick Park.
Another London hospital has been forced to turn back coronavirus patients.
Some of the people infected with Covid-19 have been dispatched to other nearby sites to help ease the pressure on overwhelmed personnel.
The potential lack of critical care beds in England has been the major concern around coronavirus, and trusts are now repurposing wards and retraining staff to try and create more capacity.
The trust - which saw three deaths in the recent wave - insisted that everyone who needed ventilation had it.
But he said it was "disturbing" to hear some people in London "filled" beyond what was achievable. "But that's not the national guidance now and there just aren't enough testing kits to do it".
