WebThe (A-a)DO2 remains normal. Hypoxic stimulation of respiratory drive increases alveolar ventilation and decreases PaCO2 level. This type of hypoxemia responds to supplemental oxygen. Carbon Dioxide PCO2 normally is maintained between 35 and 45 mm Hg. WebDespite receiving the same blood volume per minute as the systemic circulation the pulmonary circulation is a low-pressure system. Systolic pressure is normally only 25 mmHg, compared to 120 in the systemic circulation, diastolic is 8, compared to 80 and mean pulmonary artery pressure is only 15. These numbers are well worth remembering.
