Important Note

This test can only be collected at the Main Campus 111 Colchester Avenue Burlington Vermont. See Special Test considerations.

Remove needle, cap the syringe, and transport sample on ice immediately to the laboratory.

Tests included are pH, pCO2, tCO2, O2 Saturation and Base Excell/Deficit.

Arterial Blood Gas specimens are collected by Respiratory Therapy, Nursing, and Physicians.

The Laboratory recommends that the Modified Allen test be performed to determine that collateral circulation is present from the ulnar artery in the event that thrombosis of the radial artery should occur. Performance of the Modified Allen test should be documented in the patients’ chart. For further information about the indications, complications, and collection of arterial blood gas collection please refer to the AARC Clinical Practice Guidelines (Respir Care 1992:37:913-917).
