What device is most useful for toddlers who require supplemental oxygen? A) nasal cannula B) oxyhood C) croup tent D) none of the above
A) Nasal cannula. For toddlers, a nasal cannula is usually the most practical and best-tolerated way to deliver low to moderate supplemental oxygen while allowing movement, feeding, and interaction. An oxyhood is mainly used for infants, and a croup tent is rarely used today.
What the question is really testing
This is asking which oxygen-delivery device best fits a toddlerโs size, behavior, and typical oxygen needs. Toddlers need something they can tolerate while still letting them eat, talk, and move around.
Matching each option to the usual age group
- Nasal cannula: Common for toddlers and older children. It is lightweight, easy to apply, and allows normal activities.
- Oxyhood: A plastic hood that delivers oxygen around the head. It works best for infants, because it requires the head to stay under the hood and is not practical once children are more mobile.
- Croup tent: An older method of humidified mist/oxygen in an enclosure. It is rarely used due to poor oxygen control and practical issues (hard access to the child, inconsistent $FiO_2$).
Why the nasal cannula is the best answer
Toddlers are active and often resist masks or enclosed devices. A nasal cannula can deliver supplemental $O_2$ effectively at low flows, is better tolerated, and supports everyday needs like feeding and comfort.
Quick elimination
- B (oxyhood) fits infants more than toddlers.
- C (croup tent) is outdated and not a go-to device for routine oxygen delivery.
- D (none of the above) is incorrect because nasal cannula is appropriate for toddlers.
