Official Title
Exertional Desaturation as a Marker of Risk - Validation Study for the 40-steps-test; A Multi-centre Prospective Observational Cohort Study
Brief Summary

Exertional desaturation is a feature of COVID-19. The study will measure vital signs of patients discharge by practitioners in primary care, secondary care or by paramedic practitioners. Patients will then undertake a 40-steps on the spot walk followed by measurements of heart rate and oxygen saturations for up to two minutes. Association of desaturation with 30 days hospital admission and mortality will be reported.
