The condition of care in the critical care unit scenario, based on the perception of the patient hospitalized in an ICU, is being analyzed as an object of study because it represents a situational crisis for the patient, caused by the critical condition of his health, in an environment with advanced technology where the nursing professional and the patient coincide. In such a way that the connection of the patient with the environment is broken, which implies that he depends on humanized care. The objective of this study was to determine the patient's perception of humanized nursing care during his stay in the ICU at the Naval Medical Center. In view of this, a Descriptive and Cross-Sectional (Observational) study was carried out, using the instrument "Perception of humanized nursing care behaviors 3rd version". It was applied to 30 patients hospitalized upon discharge from the ICU between October and November 2020. To do this, we considered variables such as sex, age, days of hospital stay. Corresponding statistical analysis was developed to determine the distribution of the data in a parametric or non-parametric manner, as well as to perform Pearson or Spearman correlation tests as appropriate between the level of satisfaction with the nursing service and the different variables measured, with the support of the GraphPadPrism 7 software. Obtaining the following results: It was observed that 50% of the patients "always" felt with the humanized care measures described in the survey conducted. The average perception of humanized care for the 30 patients surveyed was 3.97 out of a maximum of 4 points, which is equivalent to 99.25 as a percentage. Therefore, we could assert that the way in which the nursing services carry out their work is highly professional. The age range of the patients was mostly over 40 years old with 53%, then patients between 31-40 years old equivalent to 37% and only 10% patients between 26 and 30 years old. A 37% of people were male (37%, n=11) and mostly female with 63% n=19). It was concluded that the patients' perception of humanized care was highly satisfactory in all patients surveyed at the Naval Medical Center. No statistically significant relationship was found between the days of hospital stay and the patient's humanized care.
