[Study of CNV in patients with chronic respiratory insufficiency (author's transl)].
Chronic respiratory insufficiency (CRI) has physiological and psychological aspects that we have tried to examine with the CNV. The study is related to the CNV of 15 CRI patients and 14 control subjects (Cir.). The duration and amplitude of the CNV are more developed in CRI patients. The latter show an increased frequency of prolonged CNV and also a predominance of negative phenomena during the post-imperative period of the CNV. 'Delayed CNV' are very rare among CRI patients, but they are present among 60% of Ctr. subjects. The 'field dependency CNV' are not more frequent in either group. Various factors, most likely related to those CNV modifications, are discussed (aetiologies, chronicity, adaptation, personality).
