The best pulse to check on an infant is the brachial pulse.
Why the Brachial Pulse is Preferred
While other pulse points exist, the brachial artery is the most accessible and reliable for infants:
- Location: The brachial artery is located on the inner upper arm, between the bicep and tricep muscles.
- Accessibility: Infants don't have prominent necks, making it difficult to locate the carotid artery. The brachial artery is more readily palpable.
- Reliability: Due to its location and size, the brachial pulse provides a clear and reliable indication of circulation in infants.
How to Locate the Brachial Pulse
- Position the Infant: Gently position the infant on their back.
- Locate the Artery: Find the inner aspect of the upper arm, midway between the shoulder and the elbow.
- Palpate Gently: Use two or three fingers to gently press into the area, feeling for the pulse.
- Count the Pulse: Once located, count the number of beats for 15 seconds and multiply by four to determine the heart rate in beats per minute (BPM). For accuracy, especially if the pulse is irregular, count for a full 60 seconds.
Other Pulse Points (Less Ideal for Infants)
- Carotid: Located in the neck, this is difficult to find in infants due to their short necks.
- Femoral: Located in the groin, this can be challenging to access and palpate, especially with clothing.
- Radial: Located in the wrist, this pulse may be weak and difficult to detect in infants.
In summary, while other pulse points exist, the brachial pulse provides the most reliable and accessible method for assessing an infant's circulation.
