Introduction:

Mechanical ventilation is an essential part of the therapeutic care for patients admitted to intensive care units.

Objective:

To characterize clinical and epidemiologically the patients treated with invasive ventilation.

Methods:

An observational, descriptive and cross-sectional study of 108 patients treated with invasive mechanical ventilation was carried out in the Intensive Cares Unit of Orlando Pantoja Tamayo General Provincial Hospital in Contramaestre municipality, in Santiago de Cuba province, from January to December, 2022. In the statistical analysis, the absolute frequency and the percentage were used for the qualitative variables, as well as the mean and the standard deviation for the quantitative ones, in addition to the chi-square test with a confidence level of 95% to demonstrate association between these variables.

Results:

In the series, there was a prevalence of the female patients (55.5%) at advanced ages (47.3%) with malnutrition (52.8%), mechanical ventilation during more than 96 hours (63.9%), and a punctuation higher than 2 (60.5%) according to the scale of organic failure; 30.6% presented complications and 48.1% died. Pneumonia was the most frequent cause in beginning invasive ventilation (36.1%).

Conclusions:

There was a high frequency of females at advanced ages and with malnutrition. Besides, the sequential evaluation of organic failure was related to mortality and the causes that led to invasive ventilation were associated with death and complications.
