Case Study 1:
A 55-year-old COPD patient is admitted to the hospital with acute hypoxemia. The physician orders oxygen therapy to maintain SpO₂ between 88-92%. Which oxygen delivery device would you choose, and why? Include the recommended flow rate and FiO₂.
Case Study 2:
A 70-year-old patient with pneumonia and severe hypoxemia requires a FiO₂ of 60% to stabilize oxygen saturation. Which device is most appropriate, and what is the flow rate needed to achieve this?
Case Study 3:
A post-operative 50-year-old female is recovering from abdominal surgery. She complains of mild shortness of breath; her SpO₂ is 92% on room air. What oxygen device would you recommend, and at what flow rate?
Case Study 4:
A 35-year-old patient with carbon monoxide poisoning presents to the emergency room. His SpO₂ appears normal, but the physician insists on aggressive oxygen therapy. Which oxygen device is the most appropriate, and what is the expected FiO₂?
