A blood gas analyser evaluates five critical parameters from a single arterial blood sample: PaO2 (oxygen pressure), PaCO2 (carbon dioxide pressure), pH (acidity), HCO3- (bicarbonate buffering capacity), and SaO2 (oxygen saturation on hemoglobin). Together these measurements provide a real-time snapshot of both respiratory function and acid-base balance. Clinicians use this single test to rapidly diagnose conditions like hypoxemia and respiratory acidosis at the bedside.
