All Wales COVID-19 Secondary Care Management Guideline

Triage of a patient with suspected COVID-19

Patients presenting to hospital with suspected COVID-19 need triaging; those who need admission to hospital and those who can be discharged. For the purpose of this classification system, patients should be classified according to the degree of oxygenation failure; severe, moderate and no oxygenation failure.


SEVERE OXYGENATION FAILURE

  • SpO2 less than 90% despite maximal oxygen therapy using ward-based devices (facemask oxygen at a flow rate of 10 L/minute OR using a non-rebreather mask OR using a Respiflo at 98% FiO2)

Admit the patient, and perform a throat swab to confirm COVID-19

 

MODERATE OXYGENATION FAILURE

  • Requires less than maximal oxygen therapy via ward-based devices (nasal cannulae OR facemask oxygen OR a non-rebreather mask OR Respiflo), to maintain SpO2 between 90% and 94%.

Admit the patient, and perform a throat swab to confirm COVID-19

 

NO OXYGENATION FAILURE

  • SpO2 within the normal range (94-98%) on room air

Discharge from hospital, instruct the patient to self-isolate according to local protocol, and re-present to hospital if their symptoms deteriorate.
