A schoolboy who died from an asthma attack after his family's 999 call was downgraded by a computer algorithm could 'possibly' have survived if he had received medical attention sooner, an inquest heard. Martin Sullivan, a talented musician from Ashton-under-Lyne, Greater Manchester, died at Tameside General Hospital after fighting for breath in November 2019. The 15-year-old, who had been to hospital twice following asthma attacks in 2015 and 2016, took regular medication but his parents believed his condition was well managed and under control. An inquest into Martin's death concluded at Stockport Coroner's Court yesterday. Coroner Andrew Bridgman recorded that Martin died of natural causes but said that his death could have 'possibly' been avoided if he had received medical attention sooner.
