Where do you check for a pulse on an unresponsive child or adult?

Checking for a pulse is a critical step in assessing an unresponsive individual, as it helps determine the presence of circulation. In both children and adults, the carotid arteries are the most reliable site for pulse assessment in emergency situations. The carotid arteries are located in the neck, which allows for easier access and a stronger pulse signal compared to other locations. This area is particularly advantageous because it is typically less obstructed and can be palpated more easily, ensuring that rescuers can efficiently evaluate a person's cardiac status.

Other locations, such as the brachial arteries in the inner arm or the radial arteries at the wrist, may not provide as clear or strong a pulse in an unresponsive individual, particularly if there is any minimal circulation. Additionally, checking the popliteal arteries behind the knees is not practical in such scenarios, as the position of the individual may hinder access, and blood flow may be less detectable. Thus, using the carotid arteries is the recommended and most effective practice in emergency situations for pulse assessment.
