In case of a choking toddler, which artery should be checked to gain a pulse after obtaining consent from the parent?

The brachial artery is the correct choice when checking for a pulse in a choking toddler, especially after obtaining consent from the parent. This artery is located in the upper arm and is particularly recommended for infants and young children, as it is more accessible than other pulse sites in this age group.

In emergencies involving toddlers, alternative pulse sites such as the carotid artery or radial artery may be less effective due to the size and physiology of a child's body. The carotid artery, located in the neck, can be challenging to palpate due to the small size of the child and the risk of causing distress to both the child and the caregivers. Similarly, the radial artery, found at the wrist, can be difficult to locate in young children because of their smaller wrists.

The femoral artery, while an important location for pulse checks in older individuals or in cases of severe trauma, is not commonly used for assessing a pulse in toddlers. In everyday situations like choking, the brachial artery offers a quick and reliable method to check the child's pulse and respond accordingly.
