![]() In cases of pure hypoventilation, the (A-a)DO2 is normal. Hypoventilation (reduced alveolar ventilation) decreases the PAO2 and increases the PaCO2, thereby decreasing PaO2. Supplemental oxygen can correct hypoxemia due to low V/Q ratio by increasing the PAO2, although the increased (A-a)DO2 persists. V/Q mismatch can also occur when there is increased blood flow even when ventilation is normal, as in liver disease. As a result, systemic venous blood passes through the pulmonary capillaries without achieving normal levels of PaO2. In disease states, dysregulation leads to perfusion of alveolar units that are receiving less than complete ventilation (V/Q mismatch). In normal lungs, regional perfusion closely matches regional ventilation because arteriolar vasoconstriction occurs in response to alveolar hypoxia. read more and asthma Asthma Asthma is a disease of diffuse airway inflammation caused by a variety of triggering stimuli resulting in partially or completely reversible bronchoconstriction. Alpha-1 antitrypsin deficiency and various occupational. Low V/Q ratio is one of the more common reasons for hypoxemia and contributes to the hypoxemia occurring in COPD Chronic Obstructive Pulmonary Disease (COPD) Chronic obstructive pulmonary disease (COPD) is airflow limitation caused by an inflammatory response to inhaled toxins, often cigarette smoke. Patients with anemia have lower DLCO values that correct when adjusted for hemoglobin values. Reduced DLCO also occurs in patients with previous lung resection because total lung volume is smaller, but DLCO corrects to or even exceeds normal when adjusted for V A because increased additional vascular surface area is recruited in the remaining lung. read more, decrease both DLCO and alveolar ventilation (V A).

Conditions that affect the lung diffusely, such as emphysema Chronic Obstructive Pulmonary Disease (COPD) Chronic obstructive pulmonary disease (COPD) is airflow limitation caused by an inflammatory response to inhaled toxins, often cigarette smoke. read more and pulmonary embolism Pulmonary Embolism (PE) Pulmonary embolism (PE) is the occlusion of pulmonary arteries by thrombi that originate elsewhere, typically in the large veins of the legs or pelvis. In pulmonary hypertension, pulmonary vessels may become constricted. It has many secondary causes some cases are idiopathic.
