What should be ensured regarding the portable Oxygen for infant use?

In the context of providing portable oxygen for infants, using low flow oxygen is crucial to ensure the safety and effectiveness of the treatment. Infants have different physiological requirements compared to adults; therefore, delivering oxygen at a high flow rate can lead to various complications, such as respiratory depression or oxygen toxicity.

Low flow oxygen provides a gentler and more controlled way to meet an infant's needs without overwhelming their delicate respiratory system. This method allows for the proper titration of oxygen levels to maintain appropriate saturation, which is vital for the infant's health and well-being.

The other options, such as using high flow, providing limited quantity, or using an adult mask, are inappropriate for infants. High flow can introduce risks of hyperoxia, while limited quantities might not provide adequate support, and an adult mask does not fit the smaller facial structure of infants properly, leading to ineffective delivery of oxygen.
