An inquest has resumed into the death of a two-month-old baby girl after her oxygen saturation alarm was “turned off” before she tragically died.

Louella Sheridan, of Daffodil Road, Farnworth, died on April 24, 2022, at the Royal Bolton Hospital after her oxygen levels declined.

During day four of the inquest (June 12) more concerns were raised over why the alarms were silenced for the respiratory rate, blood pressure, and heart rate, as well as why no data was available from the machine.

Account manager for Philips Sarah Sugden said that nurses would have to individually change these settings, but that there was an option to turn off or on all of the alarms.

She said: “There are short cut keys, but you have to physically click on the button on the screen, and it will give you a warning and you would have to confirm that.”

Coroner Professor John Pollard also asked Miss Sugden why adult settings were set up for a paediatric profile.

She said: “Any nurse will change alarm limits for that patient.

“If the alarm limits hadn’t been changed there would be an alarm all the time, so they must have been changed at some point.

“There will be different parameters for the heart rate, saturation, and blood pressure.”

Questions were also brought up over why there would be no patient data available on the monitoring system.

Miss Sugden explained that the machine holds 48 hours of data, but when a patient is discharged or the monitor is plugged into another machine, the system goes into default mode and deletes the data.

She said: “It does give you a warning asking if you want to end case or are you sure it’s a new patient?

“It says you will lose all data.

“You would never want to merge two patients’ data together.”

Paediatric matron Andrew Butler was also questioned over his training after he says he hadn’t had any training on the system since 2009 at the previous trust he worked at, before working at the Royal Bolton Hospital.

He said: “I have previously worked in an intensive care unit, so I have had training previously.”

The inquest also heard that following Louella’s death that although the module part of the machine was “placed in a drawer”, there was “no marker” to show it was out of order, and it was not quarantined "straight away" or "properly".

The inquest is expected to resume today (Wednesday June 13) with more evidence expected to be heard.
