Final answer:
With a flowmeter set at 6 L/min, a nasal cannula would deliver up to 44% oxygen.
Step-by-step explanation:
With the flowmeter set at 6 L/min, the nasal cannula will deliver up to 44% oxygen. When using a nasal cannula, the delivered oxygen concentration increases by about 4% for each 1 L/min of flow rate starting from 1 L/min. Therefore, at 1 L/min, it delivers 24% oxygen, and at 6 L/min, the percentage of delivered oxygen is 24% + (5 x 4%) = 44%. The percentage of oxygen delivered by a nasal cannula at a flow rate of 6 L/min can vary based on factors such as the patient's breathing pattern and anatomy. However, as a general guideline, a flow rate of 6 L/min typically delivers approximately 24% to 44% oxygen concentration. The specific percentage within this range depends on individual factors and cannot be precisely determined without additional information. In clinical settings, healthcare providers often use a flow rate of 6 L/min when administering oxygen via a nasal cannula to achieve a moderate level of oxygen supplementation.
