COVID-19 (40 Step Desaturation Test)

NHS England has introduced the use of a “40 step desaturation test” into discharge planning from the ED. You will have heard Covid -19 patients complaining of increasing SOB on exercise, and it’s important that we test this prior to discharge.

Method:

  • Is this appropriate? – Could the patient walk 40 steps before they were ill?
  • Patient remains in cubical – with mask on
  • Attach Sats probe – ensure good trace
  • Walk on spot 40 steps 
  • Monitor SaO2
