Explanation:
Detailed explanation-1: -The partial pressure of carbon dioxide (PCO2) is the measure of carbon dioxide within arterial or venous blood. It often serves as a marker of sufficient alveolar ventilation within the lungs. Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa.
Detailed explanation-2: -The pCO2 and pO2 in oxygenated blood i.e., arterial blood is 40 mm Hg and 95 mm Hg respectively.
Detailed explanation-3: -That means that PO2 in the pulmonary capillary blood = 104 mmHg. 2) PCO2 in alveoli is at 40 mmHg vs. 45 mmHg in blood returning from tissues.
Detailed explanation-4: -PaO2 (75-100 mmHg) PaCO2 (35-45 mmHg)
