Which method is associated with long-term care in infants?

The nasal catheter is particularly associated with long-term care in infants due to its less invasive nature and ability to provide a consistent flow of oxygen over an extended period. This method allows for effective oxygen delivery while minimizing discomfort for the infant. Unlike other methods, the nasal catheter can be used for prolonged periods, which is often necessary in clinical situations where infants may require sustained oxygen therapy.

In contrast, the nasal cannula, while also used for oxygen delivery, is typically more suited for outpatient or short-term use, offering less effective delivery in cases of severe respiratory distress. The transtracheal catheter is a more invasive procedure involving a direct connection to the trachea, which, while effective for certain patients, is generally not the first choice for infants who require long-term care. The simple mask, although capable of delivering oxygen, tends to be less comfortable for prolonged use in young children and infants, making it less ideal for long-term applications.

Overall, the selection of nasal catheter for long-term care is based on the need for continuous, low-flow oxygen therapy while ensuring the comfort and safety of the infant.
