ClinConnect Summary

In clinical practice blood gas analysis is an essential tool for monitoring respiratory status. The gold-standard method is arterial blood gas analysis (ABG) of blood from the patient's radial or femoral artery. An alternative to arterial sampling commonly used is arterialized capillary blood gas analysis from the earlobe (CBGE). Though CBGE is less invasive and can be performed by non-medical staff, it is less useful in the acute setting because an adequate vasodilatation is needed which typically lasts for at least 10 minutes and the quality of results tends to be operator dependable.
