118 patients suffering from severe chronic respiratory failure were submitted to domiciliary artificial ventilation (V.A.D.T.) by tracheotomy using a fixed rate volumetric respiration. The daily length of V.A.D.T. was 10 to 16 hours. The improvement on the blood gases, their stability, the disappearance of signs of right heart failure and polycythaemia, as well as a large reduction in mean length of hospital stay per subject and per year after V.A.D.T., underlined the efficacy of this method. In the long term (10 years) there was a 50% survival in patients with restrictive respiratory failure and of 33% in subjects with a mixed respiratory failure, which was predominantly restrictive. It was lower with mixed respiratory failure that was predominantly obstructive (20%). No patient with isolated airflow obstruction survived more than six years.
118例严重慢性呼吸衰竭患者通过气管切开术采用定容型固定频率通气进行家庭人工通气（V.A.D.T.）。V.A.D.T.的每日时长为10至16小时。血气改善情况、其稳定性、右心衰竭和红细胞增多症体征的消失，以及V.A.D.T.后每位患者每年平均住院时长的大幅缩短，均凸显了该方法的有效性。从长期来看（10年），限制性呼吸衰竭患者的生存率为50%，以限制性为主的混合性呼吸衰竭患者的生存率为33%。以阻塞性为主的混合性呼吸衰竭患者的生存率较低（20%）。单纯气流阻塞患者无一存活超过6年。
