Pulmonary edema c. Atelectasis b. Pulmonary emboli d. Pneumonia ANS: B A pulmonary embolus that impairs blood flow to a segment of the lung results in an area where alveoli are ventilated but not perfused, which causes alveolar dead space. Alveolar dead space is not the result of any of the remaining options. PTS: 1 REF: Page 1252 11.

Pulmonary edema. Pulmonary edema is fluid accumulation in the tissue and air spaces of the lungs. It leads to impaired gas exchange and may cause respiratory failure.

Pulmonary edema may be caused by a number of cardiac or non-cardiac conditions. Breathing difficulty is the main manifestation of pulmonary edema. Treatment of the underlying cause of pulmonary edema is an essential step in the management of pulmonary edema.

Pulmonary edema is an accumulation of fluid within the parenchyma and air spaces of the lungs. Classically it is cardiogenic (left ventricular) but fluid may also accumulate due to damage to the lung. This damage may be direct injury or injury mediated by high pressures within the pulmonary circulation.

By Mayo Clinic Staff. Several factors are needed to continuously supply the cells and tissues in your body with oxygen: There must be enough oxygen in the air you are breathing. Your lungs must be able to inhale the oxygen-containing air — and exhale carbon dioxide. Your bloodstream must be able to circulate blood to your lungs, take up the oxygen and carry it throughout your body.

Figure 3 nicely illustrates the relationship between PAO2 and PACO2 as the V/Q ratio is changed. From JB West, Pulmonary Physiology-The Essentials, 7th ed. V/Q imbalance is the most common cause of hypoxemia, a result of lung units with low V/Q ratios. An extreme case is easy to grasp – the left lung gets all the ventilation and no blood flow; the right lung gets no ventilation and all the blood flow. In this case, you have a big dead space and a big shunt.

I. Hypoventilation: Hypoxemia develops when the pulmonary alveoli are inadequately ventilated. Clinically, the hallmark of inadequate ventilation is hypercapnia, an elevated systemic arterial PCO2 (PaCO2 > 43 mm Hg). The most common cause of hypoventilation is depression of the medullary respiratory center by drugs.

Picture of the alveoli and lung. Pulmonary edema occurs when the alveoli fill up with excess fluid seeped out of the blood vessels in the lung instead of air. This can cause problems with the exchange of gas (oxygen and carbon dioxide), resulting in breathing difficulty and poor oxygenation of blood.
