Final answer:
Capillary blood from an infant is commonly collected from the heel through a heel stick procedure. It is a safe and minimally invasive method to obtain blood samples necessary for medical analysis.
Step-by-step explanation:
Capillary blood is typically collected from infants using a technique that involves the puncture of the skin to access the tiny capillaries, which are small blood vessels that connect arterioles and venules. In infants, a common practice is to collect capillary blood from the heel, known as a heel stick, to minimize discomfort and complications. This procedure is often done to perform various blood tests that require small amounts of blood. During the heel stick procedure, proper care should be taken to ensure that the puncture is made in the recommended area of the heel to avoid bone injury and to maximize blood collection.
It’s important to note that blood collection in infants should always be performed by trained healthcare providers to ensure safety and accuracy. In the context of an infant’s circulatory adjustments at birth, the heel stick is a minimally invasive method to obtain the necessary blood samples while maintaining the integrity of the infant’s delicate circulatory system.
