Arterialization of a Skin Puncture Sample By Warming the Skin

Specialty:

Clinical Laboratory

Objective:

ICD-10:

Description:

Warming the skin prior to skin puncture increases blood flow through the capillaries, making its composition resemble that in small arteries. This is called arterialization of the sample. In theory this could allow for collection of a capillary sample that could give blood gas results similar to an arterial sample. The increased blood flow increases the chances of collecting an adequate blood sample.
