Background: mechanical ventilation is the most used technique of substitution of organs and systems in intensive care units (ICU) and operating rooms. There are difficulties regarding the choice of the mode of ventilation during angiology surgeries since ventilation has latent complications for patients. Objective: to compare the modes of mechanical ventilation in patients who underwent an angiology surgery. Methods: a prospective, longitudinal, analytical study was conducted. The universe was composed of 85 patients. The sample included 64 patients who underwent an angiology surgery and were administered general anesthesia in Manuel Ascunce Domenech Teaching Hospital in Camagüey. Anesthesia histories were the source of information. The studied variables were O₂ saturation, O₂ pressure and CO₂ pressure; ventilatory and hemodynamic parameters; as well as the recovery time. Two groups of people in the same stages of life and with similar personal pathological histories underwent randomly the two modes of study. Results: the oxygenation parameters, the plateau pressure, the arterial pressure, and the recovery time did not show significant differences between the groups. The heart rate was higher within the normal limits in the assisted mode. Conclusions: there is not enough evidence to recommend a transoperative ventilation mode or another for angiology patients. It is recommended to use the assisted mode in patients with an increase in the peak pressure and the controlled mode in patients with high heart rates and in ischemic heart diseases.
