An observational, descriptive and cross sectional study of the 98 patients with lung obstructive worsened chronic disease, ventilated in a non invasive way in the intensive care unit of "Saturnino Lora Torres" Teaching Provincial Clinical Surgical Hospital in Santiago de Cuba was carried out from January of 2011 to the same month of 2015, in order to characterize them according to social demographic, clinical, ventilatory and hemogasometric variables. In the series a higher percentage failure was obtained compared to the world statistics. The patients with unfavorable clinical course and older than 65 years and with hospital stay longer than 7 days prevailed ; also, the duration, frequency, the modality used in the non invasive ventilation and the triggering factors, had no significance in the result of the technique. The Ph, PaCO2, respiratory and heart frequencies, as well as the Glasgow coma scale, evidenced improvement in the patients with favourable clinical course. The failure of this technique was related to an increase in mortality (83%)
