Hypoxic Ischaemic Encephalopathy due to out of hospital cardiac arrest, secondary to acute bacterial pneumonia on a background of obstructive sleep apnoea and morbid obesity; hypertension as significant contributing condition
AI-generated summary
Richard Navarro, a 43-year-old man with severe obstructive sleep apnoea (OSA), morbid obesity, hypertension, and recurrent pneumonia, died of hypoxic ischaemic encephalopathy following cardiac arrest while in custody at Silverwater Correctional Centre. He collapsed during sleep approximately one hour after lights-out on his first night in custody, without access to his custom CPAP machine (which his family was bringing the next morning). The coroner found no evidence of negligence by Corrective Services or Justice Health. However, clinical lessons include: (1) OSA with obesity carries serious unrecognised risks; (2) Mr Navarro had undiagnosed obesity hyperventilation syndrome (OHS), a more dangerous condition; (3) he failed to attend recommended annual sleep studies post-2010, did not follow cardiology risk-reduction advice, and self-discharged against medical advice; (4) the coroner could not confirm the one-hour CPAP absence contributed to death given his deteriorated health status. Systemic issues identified include inadequate screening for high-risk sleep disorders in custodial settings and resource constraints preventing CPAP machine availability in correctional facilities.
