  • Continuous monitoring of vital signs- Transfer to High Dependency Unit
  • COVID-19 Management: Isolate the patient in a negative pressure room, implement infection control precautions, and monitor for progression of COVID-19 symptoms
  • Controlled oxygen therapy -Continuous pulse oximetry, to keep O2 between 88% to 92%
  • Sit patient in high fowlers position
  • 4/24 ABGs
  • Salbutamol (Ventolin) nebuliser 2/24
  • Ipratroprium (Atrovent) via nebuliser 6/24
  • Prednisolone (40–50 mg daily)
  • 12- lead ECG 6th hourly
  • Blood troponin
  • Sputum culture
  • IV Azithromycin (Zithromax) 500 mg on day 1 , followed by 250 mg once daily for the next four days.
