An arterial blood gas (ABG) is a blood test carried out by taking blood from an artery, rather than a vein. It is performed so that an accurate measurement of oxygen and carbon dioxide levels can be obtained, which then allows the patients oxygen to be d
The sample should be introduced into a calibrated blood-gas analyzer. (2-4) Duplicate or triplicate measurements are recommended, and agreement of results should be reviewed and evaluated. Ideally, ABG analysis should be performed on two different calibrated analyz...

INTRODUCTION An arterial blood gas (ABG) is a test that measures the oxygen tension (PaO 2 ), carbon dioxide tension (PaCO 2 ), acidity (pH), oxyhemoglobin saturation (SaO 2 ), and bicarbonate (HCO 3 ) concentration in arterial blood. Some blood gas analyzers also measure the met...
Blood gas analysis is integral to assessing emergency department (ED) patients with acute respiratory or metabolic disease. Arterial blood gas (ABG) is the gold standard for oxygenation, ventilation, and acid–base status but is painful to obtain. Periph
In the field of blood gas interpretation, confusion about PaO2, SaO2and oxygen content is second only to confusion about mixed acid-base disturbances. Arterial PO2(little 'a')gives us valuable information about adequacy of gas exchange within the lungs, when (and only when) it is subtracted ...

Alveolar gas exchange depends not only on alveolar ventilation, but also on blood circulation through the alveolar capillaries. Sepsis and septic shock are the leading causes of ICU admission. Cytokines released during the inflammatory response in sepsis can cause extensive vasodilation, leading to ...
The ABGA values (PH, PaO2, PaCO2, K+, Na+, THbc) of 54 patients during thoracoscopic surgery were test unobstructed blood collection lines, and stable ventila- tor mode (oxygen level 60%; PEEP 5; frequency 14). Air contact was blocked immediately after sample collection, and blood gas ...
