What is the healthy range for pCO2 in mm Hg?

The healthy range for pCO2, which refers to the partial pressure of carbon dioxide in arterial blood, is typically considered to be between 35 and 45 mm Hg. This range is critical as it reflects the balance between the production and elimination of CO2 in the body, which directly influences the acid-base status and respiratory function.

The correct answer reflects a misunderstanding, as the ideal range is not within those boundaries provided. It's essential to clarify that the normal range for pCO2 would not fall outside the standard values previously mentioned. The values given in other options also fall short of the standard understanding. The ranges are not clinically accepted as normal, indicating potential respiratory distress or metabolic issues if consistently observed.

Establishing an accurate pCO2 range is vital for monitoring respiratory health and ensuring proper gas exchange during both fetal and maternal assessments.
