Arterialized ear lobe blood samples for blood gas tensions

Br J Dis Chest. 1976 Oct;70(4):263-8. doi: 10.1016/0007-0971(76)90042-5.

Abstract

The accuracy of arterialized blood samples both at rest and during exercise is described in comparison to simultaneous arterial blood samples. The technique was found to be reliable and sufficiently accurate for clinical exercise testing, with no significant differences for Po2 or Pco2 between the two methods.
