Introduction:

prone ventilation is ventilation that is administered with the patient lying prone, it can be used for the treatment of ARDS mainly as a strategy to improve oxygenation when more traditional modes of ventilation fail.

Objective:

to know if there is an association between the initial tomographic category and the response to ventilation in the prone position.

Material and methods:

observational, analytical, longitudinal and retrospective study of all the clinical records of patients hospitalized in the Intensive Care Unit from June 2020 to June 2021 with invasive mechanical ventilation in the prone position, who underwent chest tomography at hospital admission in the period.

Results:

66 clinical records were included, of which 48 were male and 18 female. The mean age was 51 years. In the initial tomography, the majority corresponded to a tomographic category C with up to 48.5% and in a lower percentage to tomographic category A and B with a frequency of 27.3 and 24.2% respectively. Tomographic category B had the highest percentage of responders in the prone position up to 87%, category A and C had a percentage of responders of 66.7 and 44.7% respectively, without statistical significance, perhaps due to the limited number of patients.

Conclusions:

patients with category B were the ones that best responded to this strategy. There is a relationship between the category and the response to mechanical ventilation in the prone position.
