2. Material and Methods • Total 187 patients older than 18 years referring to the ED of Imam Hossein Teaching Hospital (Tehran, Iran) • ABGA • Arterial blood samples were taken after carrying out Allen test and explaining the procedure to the patients. A heparinized insulin syringe was used at an angle of 45° under aseptic conditions to take a 0.5-mL sample from the radial artery. The air inside the syringe was immediately evacuated to increase the accuracy of the test. • CBGA • a lancet was used to produce a cut 3mm in depth on the lateral side of the distal phalanx of the third finger of the hand under aseptic conditions. The first blood drop was wiped away, and a heparinized plastic capillary tube was used to collect 150 μL of capillary blood sample. • Excluded : SBP < 80mmHg, supplemental oxygen before sampling
