A "talented" university graduate died after spending more than an hour in a hospital corridor where a nurse gave her an oxygen mask that wasn't connected to anything, an inquest has heard. Clarissa Street, 24, had suffered a pulmonary embolism and was taken to A&E at Royal Oldham Hospital after spells of dizziness and feeling unwell. The University of Manchester graduate, who studied Sociology and earned the Dean's Award for her dissertation, tragically died just hours later on August 14, 2024.
