What is the expected PCO2 in respiratory alkalosis?

Greater than 40

Less than 40

In respiratory alkalosis, the pCO2 (partial pressure of carbon dioxide) levels are lower than normal due to hyperventilation, which results in excessive exhalation of carbon dioxide. Typically, normal pCO2 levels range from about 35 to 45 mmHg. When a patient is in respiratory alkalosis, the pCO2 drops below the normal range, often falling below 35 mmHg. This decrease in carbon dioxide is a compensatory mechanism in response to hyperventilation, where the increase in respiratory rate leads to a reduction in CO2 levels. This physiological change effectively illustrates the body's attempt to restore balance in the acid-base status of the blood, making the understanding of these values crucial for paramedics and healthcare professionals diagnosing respiratory conditions.
