Causes of chronic respiratory failure were tuberculosis sequelae in 12, chronic pulmonary emphysema in 20, diffuse panbronchiolitis in 3, bronchiectasis in 10, interstitial pneumonia in 5 and others in 3. The arterial oxygen tension (P_aO_2) in room air of all patients at the initiation of HOT was 58.3±8.1 Torr. In twenty three cases P_aO_2 level at the initiation was more than 60 Torr, some of which showed signs of load on right heart on ECG and/or cardiac echogram. Both infection of the respiratory tract and heart failure were the most common factors of acute exacerbation in home oxygen therapy patients. Twenty cases died during the course of HOT. Of the total cases 85% of the deaths were due to respiratory insufficiency and 5 of them died at home. The three-year survival rate for patients on HOT was 56.9% in all patients. The degree of dyspnea and development of cor pulmonale were well correlated to prognosis, but there was no correlation between prognosis and underlying disease, pulmonary function and initial blood gas data. It was thought that the selection criteria for HOT should be decided from the viewpoint of P_aO_2 level reflecting tissue hypoxia and load on the right heart. To improve the daily-life activity of the patients on HOT not only the medical support system but also the support of the community was thought to be indispensable.}, pages = {579--584}, title = {4)当院における在宅酸素療法の現状とその問題点(シンポジウム 在宅医療は可能か?, 第472回新潟医学会)}, volume = {107}, year = {1993} }
