Item Distribución del volumen pulmonar mediante tomografía de impedancia eléctrica durante una maniobra de titulación de PEEP en pacientes con SDRA moderado- severo asociado con COVID-19(Universidad Santiago de Cali, 2024) Benítez, María Camila; Lozano, María José; Segura, Alejandro (Director)This retrospective observational study aimed to determine lung volume distribution in 21 adult patients with COVID-19-associated ARDS using an Electrical Impedance Tomography (EIT) monitor during a decremental Positive End-Expiratory Pressure (PEEP) titration maneuver. The results indicated that ventilation was better in the basal zone than the ventral zone. Optimal PEEP levels were identified in the $18-16-14 \text{ cmH}_2\text{O}$ range for high values and $12-10 \text{ cmH}_2\text{O}$ for low values, with the largest change in lung volume (peak $\Delta\text{EELI}$) occurring between $14 \text{ and } 12 \text{ cmH}_2\text{O}$. The study concludes that the PEEP range between $12 \text{ and } 14 \text{ cmH}_2\text{O}$ was optimal for improving Functional Residual Capacity in these patients, emphasizing the importance of individualized PEEP titration guided by patient physiology.
