Nurses, midwives and paramedics are currently on strike in the city as part of a dispute about NHS pay.
The strike - which lasts for four hours and runs until 11am - will see health service staff only respond to emergency situations, with non life-threatening work not undertaken during the period.
Ambulance staff at East Midlands Ambulance Service walked out from 7am on Monday, October 13 - responding only to "life-threatening" emergencies.
They will also refuse to work overtime until the end of Friday.
And midwives at Nottingham's hospitals have also taken action - for the first time in their history.
Speaking at the time the strike was announced, Cathy Warwick, chief executive of the Royal College of Midwives, which has 26,000 members, said: "This is a resounding 'yes'. It could not send a clearer signal about the level of discontent on this issue.
"The RCM will be meeting with employers to discuss our action and to ensure that mothers and babies are not put at any risk. "
A statement from Nottingham University Hospitals NHS Trust, which runs the Queen's Medical Centre and City Hospital, said: "We will continue working closely with the RCM to make sure patient safety and urgent care will not be affected in any way by the action."
It is not known how many staff in total are on strike.
Paramedics are striking over the one per cent pay rise that has only been offered to staff on the top pay band, denying the rise to 60 per cent of NHS staff.
The ambulance service said industrial action will cause a backlog of patients with less serious injuries and illnesses.
"The action will affect all non life-threatening emergency calls we receive and it is inevitable that we will face significant pressure both during and after the period of Industrial Action," said Sue Noyes, chief executive of EMAS. "The backlog may take some time to clear and patients may therefore experience some delays throughout Monday."
However, local union members defended the action.
Lee Goddard, EMAS representative for the Unison union, said: "We are not putting any lives in danger and we would like to make it clear we are striking against the government not the trust.
"We just want fair pay for a fair job."
A retired paramedic, who did not want to be named, said ambulance staff were undervalued.
"I think we are treated like those people who should deem it a privilege to be in the health profession," he said. "The people at the sharp end haven't had a pay rise for years now."
