📖About Arterial Blood Gas Monitoring
Arterial blood gas monitoring measures the levels of oxygen, carbon dioxide, pH, and bicarbonate in arterial blood to assess how well the lungs are oxygenating blood and how effectively the body is regulating its acid-base balance. It is a critical, frequently repeated test in intensive care to guide decisions about ventilator settings, oxygen therapy, and treatment of metabolic disturbances. The rapid turnaround time, often within minutes, makes it invaluable for real-time decision-making in critically ill patients. Blood is drawn from an artery rather than a vein because arterial blood better reflects the gas exchange happening in the lungs.

- 1Blood is drawn either from a peripheral artery, most commonly the radial artery at the wrist, using a fine needle and syringe, or from an indwelling arterial line already in place for continuous monitoring. Firm pressure is applied to the puncture site for several minutes afterward to prevent bruising or bleeding, since arteries are under higher pressure than veins. The sample is analysed immediately on a point-of-care blood gas machine to provide rapid results.
