Answer :
Final Answer:
When calibrating the PCO₂ electrode of a blood gas analyzer, the gas concentration used to set the slope control should be 10%.Thus correct option is B. 10%
Explanation:
Calibrating a blood gas analyzer is crucial to ensure accurate and reliable results. The choice of the gas concentration for setting the slope control is determined by the specific requirements of the electrode being calibrated. In the case of the PCO₂ electrode, which measures partial pressure of carbon dioxide, a concentration of 10% is commonly used.
This concentration is selected based on the expected physiological range of CO₂ levels in blood samples. A 10% concentration provides a balanced and representative calibration point, allowing the electrode to accurately measure and respond to variations in partial pressure of CO₂ within the clinical range.
It's important to note that using concentrations outside the appropriate range can lead to inaccuracies in measurements, compromising the reliability of the blood gas analyzer. Precision in calibration is essential for the device to provide clinicians with precise data for making informed decisions about patient care.
