<unk><unk>  is the result of inadequate gas exchange in the pulmonary circulation. This could result from lung<unk>  or pump<unk> . Lung<unk>  which is<unk>  of gas exchange results in hypoxemia (<PaO2) and pump<unk>  which is ventilatory<unk>  would result in alveolar hypoventilation that causes hypercapnia (>PaCO2). Type I<unk><unk>  has a V/Q mismatch that causes hypoxemia. Type II<unk><unk>  is caused by alveolar hypoventilation which results in hypercapnia. Type III<unk><unk>  occurs in the peri-operative period clinically progresses to Type I or Type II<unk><unk> . Type IV<unk><unk>  results from an underlying circulatory collapse.
