7. What is the air portion only of a Venturi system running at 70% 02 concentration with a flowmeter setting of 9 L/min? 8. What is the FIO2 being delivered from a Venturi system that has an 02 flow of 5 L/min and an air flow of 40 L/min? 9. What is the 02% from a system that has two jet nebs connected in line with one system delivering 35% 02 (flowmeter setting = 5 L/min) and the other system delivering 80% 02 (flowmeter setting = 12 L/min)? 10. If your patient's minute ventilation is 14 L/min and the physician wants the patient to receive .6 FIO2 from a Venturi system, what must you set the flowmeter on to ensure adequate total flow? 11. If there is one part oxygen and 0.6 parts of air being bled into a Venturi system, what is the oxygen concentration?
