A 60-year-old male was admitted with respiratory distress. He is tachycardic and tachypneic, with an oxygen saturation of 86% on room air. The patient has an approximate spontaneous tidal volume of 500 mL and an inspiratory time of 1 second. Which of the following oxygen delivery devices can meet or exceed the patient’s inspiratory flow rate? [35% air-entrainment mask at 6 L/min/60% aerosol mask at 12 L/min/Non-rebreathing mask at 15 L/min/Simple O2 mask at 10 L/min]. A liquid O2 tank contains 5 lb of liquid O2. The patient is receiving O2 at 3 L/min through a nasal cannula. How long will the liquid O2 last?

The patient has an approximate spontaneous tidal volume of 500 mL and an inspiratory time of 1 second. Which of the following oxygen delivery devices can meet or exceed the patient’s inspiratory flow rate? [35% air-entrainment mask at 6 L/min/60% aerosol mask at 12 L/min/Non-rebreathing mask at 15 L/min/Simple O2 mask at 10 L/min]. A liquid O2 tank contains 5 lb of liquid O2. The patient is receiving O2 at 3 L/min through a nasal cannula. How long will the liquid O2 last?
