Blood Gas Analyzers. Blood gas analyzers are used to measure combinations of pH, blood gas (i.e. pCO2 and pO2), electrolytes, and metabolites parameters from whole blood samples. Blood conservation is an important initiative in every clinical diagnostic lab or critical care facility.

3. BLOOD GAS ANALYSER
Blood gas analyzers are used to
measure combinations of pH, blood
gas (i.e. pCO2 and pO2),
electrolytes, and metabolites
parameters from
whole blood samples.

4. Blood gas/pH analyzers use electrodes
to determine pH, partial pressure of
carbon dioxide, and partial pressure of
oxygen in the blood. ...
Whole blood samples are placed in
tubes, on reaction cuvettes, or on test
strips, and loaded into the analyzer.
BLOOD GAS ANALYZER WORK

5. NORMAL RANGES
pH: 7.35–7.45
partial pressure of oxygen
(PaO2): 80–100 millimeters of
mercury (mmHg)
partial pressure of carbon
dioxide: 35–45 mmHg.
The following are normal ranges for
results of a blood gas test:

6. THE TWO MOST IMPORTANT BLOOD
GASES
Oxygen (O2) and
carbon dioxide (CO2) are the
most important respiratory
gases, and their partial
pressures in arterial blood
reflect the overall adequacy of
gas exchange
Pao2 is affected by age and
altitude. Paco2 by altitude.
