Physical Activity a Vital Sign? 40 Steps to Safety Test for Patients With COVID-19

• Conditions: Covid19; Medical Emergencies

• Registration Number: NCT04618835
• Lead Sponsor: Betsi Cadwaladr University Health Board

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.
