Laboratory Point of Care
Typical Use
Collect arterial blood for blood gas and electrolyte analysis.
Description
A preheparinized syringe and needle system designed for safe arterial blood sampling that preserves sample integrity for measurement of pH, PaO2, PaCO2, and electrolytes; it minimizes air contamination and metabolic changes between collection and analysis. Proper technique includes arterial puncture skill, immediate expulsion of air bubbles, prompt cooling or analysis per protocol, and secure labeling to avoid preanalytical errors that can alter clinical interpretation. ABG sampling informs ventilator settings, oxygen therapy, and acid base management in critically ill patients and requires staff competency, infection control precautions, and adherence to institutional handling procedures. Documentation of sampling site, time, and patient condition enhances result interpretation and clinical decision making.
