title: [Research on impedance pulmonary rheogram for calculating pulmonary artery mean pressure].
abstract: A simultaneously comparative study of IPR and right catheter examination for measurement of PAMP has been done on 71 patients with COPD. The results show that the similar average value of PAMP of the examined group could be calculated by any representative equation, but at present time, an accurate predetermining value of PAMP can not be obtained by any noninvasive technique for each individual patient with COPD who has pulmonary hypertension of mild to moderate degree.
