Helen Blanchard, Interim Chief Nurse at The Queen Elizabeth Hospital King’s Lynn NHS Foundation Trust, said: “In December 2022 our routine testing has showed that some samples were above the accepted levels of nitrous oxide given in national guidance. The QEH were able to able to work with our staff to limit usage of gas and air in specific rooms, dealt with on a case by case basis, whilst we improved ventilation systems.
“At no point did we suspend the use of gas and air and we have no plans to do so in the future. We have worked with our teams to ensure that the ventilation and extraction systems used in our Maternity suites are working effectively, and there is no risk to those giving birth or their birthing partners and babies. We have a testing programme in place to ensure that we quickly identify such issues in future.”
