Abstract：To know the therapeutic effects of oxygen inhalation both via Ventrui mask and via bilateral nasal tube, 30 cases of patients with chronic obstructive pul-monary disease (COPD) were observed. The indices included arterial blood pH value, PaCO2 and PaO2 of acute exacerbation stage patients both before and after oxygen inhalation. Results showed that patients who used the Ventrui mask inhalation,the amplitude of PaO2 ascending were more and faster than that in control group (P＜0.01). Moreover, It can improve the hypoxia symptoms of the patients and did not worsen the carbon dioxide retention. Suggested that to use the Ventrui mask in acute exacerbation stage COPD patients may elevate their PaO2 and can not cause carbon dioxide retention. It can improve the hypoxia of the patients as well.
