(1) Type I respiratory failure: Paco2 _ 2 is normal or decreases only when o2 is deficient but co2 is not retained. This type of respiratory failure is also called hypoxemic respiratory failure or ventilation failure. \ x0d \ (2) Type Ⅱ respiratory failure, accompanied by CO2 retention except O2 deficiency, is also called hypercapnia respiratory failure or ventilation failure. Blood gas analysis: quiet state, breathing indoor air \ x0d \ type: pao 2 30%); \x0d\II respiratory failure oxygen flow should be
