Royal London Baby Death

A coroner has warned that more babies could die unless neonatal monitor alarms are redesigned, after a six‑month‑old boy at the Royal London Hospital died when staff couldn’t hear his alarm.

Ismaeel Islam, who had Down’s Syndrome and complex medical needs, suffered a respiratory arrest on the special care baby unit.

His oxygen‑monitor alarm had been turned down so low it was effectively silent, and his cot had been moved out of clear view. Staff did not notice his deterioration for around 30 minutes.

Senior coroner Mary Hassell said the alarm volume was a critical factor in the missed collapse. She issued a Prevention of Future Deaths report to Masimo UK, the monitor manufacturer, urging:

• Locked, non‑adjustable loud alarm settings
• Default maximum volume to prevent accidental silencing

Masimo must respond within 56 days, outlining what changes it will make.

The case has intensified scrutiny of NHS neonatal safety, with concerns that quiet or adjustable alarms pose a systemic risk — especially for vulnerable babies who rely on continuous monitoring.

Ms Hassell said Ismaeel’s death was preventable: “Had his deterioration been recognised at once and treated properly, he would have survived.”

She urged a fundamental change to alarm design, calling for monitors to be locked at maximum volume or to default automatically to the loudest setting so they cannot be turned down to unsafe levels.

Ismaeel’s underlying conditions included Down’s syndrome, significant growth restriction, and complications linked to his prematurity.

The coroner has sent a report to Masimo UK, the company responsible for the monitoring alarms used at the hospital.

Barts Health NHS Trust has since brought in new safety measures, including louder, more reliable alarm settings and improved cot positioning to ensure staff have clear lines of sight.

Masimo UK has been given 56 days to issue its response to the coroner’s report.

Public reaction ranged from heartbreak and anger to calls for accountability, with people describing the case as heartbreaking negligence, a sign of systemic failure, a design flaw by manufacturers, a reminder of how overstretched NHS staff are, and a tragedy that demands clear responsibility.
