[Long-term results of intermittent ventilatory assistance for 74 severe obstructive chronic respiratory insufficient patients (PaCO2 greater than 50 Torr) ventilated for more than a year (author's transl)].
From 1967 to 1978, home assisted ventilation (HAD) was applied to 74 severe chronic respiratory insufficient patients (67 COPD-7 restrictive). These patients used volume generators through mouth piece, except 3 of them who had a tracheostomy. The main results of this study are a highly statistically significant decrement (P less than 0,001) of the hospitalization durations and of the frequency of ARF, as well as an improvement of the survival duration in front of a non-tested group, and a significant decrease of haematocrit (less than 0,05) and P.V.R. (P less than 0,01). But blood gases and functional tests are not statistically different. Age (greater than 55 years) and delay after first ARF (greater than 2 years) when starting HAD are considered as pejorative factors.
