When assessing the heart rate of a 6-month-old infant, which pulse should be palpated?

In the assessment of a 6-month-old infant, palpating the brachial or femoral pulse is critical as it provides reliable information about the infant’s heart rate and circulatory status. The brachial pulse is located in the upper arm and is easily accessible in infants, allowing for accurate measurement. The femoral pulse, found in the groin area, is another important site because it can assess blood flow to the lower extremities and overall circulation.

For infants, the radial pulse is often difficult to palpate accurately, given their smaller and less developed wrist arteries. Similarly, while the carotid pulse can be examined, it is generally not the first choice in infants due to concerns about applying too much pressure or causing discomfort. Thus, brachial and femoral pulses are the preferred sites when assessing heart rate in young children, ensuring both accuracy and safety during the assessment process.
