Poorly oxygenated blood leaving the alveoli of those areas mixes in the pulmonary veins with oxygenated blood from well-ventilated areas of the lungs. It may be either acute or chronic.ġ) Mismatch of alveolar ventilation and pulmonary perfusion: Reduction of alveolar ventilation with an unchanged or slightly reduced pulmonary perfusion (eg, due to obstructive or interstitial lung disease, minor atelectases, or alveolar flooding) leads to lower partial pressure of oxygen in those areas of the lungs. Respiratory failure is classified as hypoxemic respiratory failure or hypercapnic respiratory failure. Respiratory failure is a dysfunction of the respiratory system causing impaired pulmonary gas exchange and resulting in hypoxemia (a decrease in the partial pressure of arterial oxygen 45 mm Hg ).
