Respiratory failure patients must be hypoxic, right?

Respiratory failure depends on the type of hypoxia, type I respiratory failure patients do not hypoxia, type II respiratory failure patients hypoxia. Respiratory failure patients do not necessarily all hypoxia. Respiratory failure is a serious disorder of pulmonary ventilation and (or) ventilation caused by various causes, so that effective gas exchange cannot be carried out, resulting in hypoxia with (or without) carbon dioxide retention, thus causing a series of clinical syndromes of physiological function and metabolic disorder. Type I respiratory failure refers to hypoxia without carbon dioxide retention or with decreased carbon dioxide (type I) seen in ventilation dysfunction Type Ⅱ respiratory failure is caused by alveolar ventilation deficiency, and the degree of O 2 deficiency and CO 2 retention is parallel, if accompanied by ventilation dysfunction, O 2 deficiency is more serious. only increase alveolar ventilation, if necessary, add oxygen therapy to correct. In addition, on the basis of type I respiratory failure, if combined with carbon dioxide retention, indicating severe respiratory damage, for type II respiratory failure. Therefore, respiratory failure patients do not necessarily hypoxia, whether hypoxia depends on the classification.
