What is a nasal cannula, and what is its flow rate range?

A nasal cannula is a medical device specifically designed to deliver supplemental oxygen directly into a patient's nostrils. This method allows for a more comfortable and less invasive way of administering oxygen compared to a mask, making it ideal for patients who may not tolerate masks well, or for those who need lower concentrations of oxygen.

The typical flow rate range for a nasal cannula is 1 to 6 liters per minute. At these flow rates, it is effective for providing low to moderate levels of supplemental oxygen, which can significantly improve the oxygen saturation in patients suffering from respiratory distress or other related conditions. This range is carefully determined to ensure patient comfort while delivering the necessary oxygen levels for effective therapy.

Choosing this option reflects an understanding of both the device's function and its appropriate usage in medical settings.
