For non-COPD patients, using a nasal cannula at a flow rate of 4-6 liters per minute (LPM) is appropriate because this range provides an adequate amount of supplemental oxygen while maintaining a comfortable delivery method. At this flow rate, patients can typically receive about 30-40% oxygen concentration, which is sufficient for those who may be hypoxic but do not have chronic obstructive pulmonary disease (COPD) or related conditions that require careful management of oxygen levels.

Using higher flow rates, such as those indicated in other choices like 8-10 LPM or 10-12 LPM, can lead to discomfort, nasal dryness, and even oxygen toxicity, which is particularly concerning in patients whose response to oxygen must be strictly managed. The lower range of 2-4 LPM may not provide enough oxygen for individuals in need of more significant support, particularly if they are exhibiting signs of respiratory distress or low oxygen saturation levels. Thus, 4-6 LPM strikes a suitable balance for non-COPD patients who need supplemental oxygen.
