Se estima que el 50 % de los casos graves o críticos que requieren manejo en unidades de cuidados intensivos fallecen.  Objetivos:  se evaluó el impacto de los modos ventilatorios usados en pacientes con covid-19 en Lombardía, Italia, en la oxigenación, la hemodinámica y la mortalidad.  Materiales y métodos:  se realizó un estudio analítico longitudinal retrospectivo en 86 pacientes críticos con covid-19, en el Hospital Mayor de Crema, en Lombardía, Italia, desde el 1 de abril al 20 de mayo de 2020. Se realizaron análisis no paramétrico y de la varianza.  Resultados:  Hubo una supervivencia del 76,7 %. El modo utilizado tuvo igual comportamiento en occisos (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) y en vivos (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10); test de x2 = 0,59; test de análisis de la varianza media índice PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV = 115) p = 0,924. La presión de final de espiración positiva (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) con p = 0,205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) con p = 0,512. La tensión arterial media (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) con p = 0,988. Modelos de cálculo de la presión de final de espiración positiva, según modo ventilatorio: BiPAP: PEEP = -0,0331 (índice PO2/FiO2) +18,215; PCV: PEEP = -0,0047 (índice PO2/FiO2) +13,717; VCRP: PEEP = -0,0204 (índice PO2/FiO2) +15,678; APRV: PEEP = -0,0092 (índice PO2/FiO2) +14,889.  Conclusiones:  la evolución del paciente crítico con covid-19 está determinada en gran medida por la ventilación mecánica invasiva; sin embargo, no existió suficiente evidencia para recomendar una u otra modalidad ventilatoria. El éxito está en conocer con exactitud las características del respirador, su modalidad y el paciente en cuestión.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  Introduction:  COVID-19 is a disease in which mechanical ventilation acquires vital importance. It is estimated that 50 % of the serious and critical patients requiring management in intensive care units die.  Objectives:  to assess the impact of the ventilation modes used in patients with COVID-19 in Lombardy, Italy, on oxygenation, hemodynamics and mortality.  Materials and methods:  a retrospective, longitudinal, analytic study was carried out in 86 critical patients with COVID-19 who entered the Main Hospital of Crema, in Lombardy, Italy, from April 1st to May 20, 2020.  Results:  the survival was 76.7 %. The used mode showed the same behavior in deceased patients (BiPAP-3, PCV-4, VCRP-4, APRV-5, VCV-4) and in alive patients (BiPAP-10, PCV-17, VCRP-14, APRV-15, VCV-10). X2 = 0.59. ANOVA test index PO2/FIO2 (PCV = 132), (BiPAP = 132) (VCV=115) p = 0.924. PEEP (BiPAP-12, PCV-13, VCRP-13, APRV-13, VCV-14) p = 0.205. PCO2 (BiPAP-55, PCV-52, VCRP-57, APRV-59, VCV-57) p = 0.512. Average blood pressure (BiPAP-84, PCV-83, VCRP-84, APRV-82, VCV-83) p = 0.988. PEEP models according to ventilation mode: BiPAP: PEEP = -0.0331 (PO2/FiO2 index) +18.215. PCV: PEEP = -0.0047 (PO2/FiO2 index) + 13.717; VCRP: PEEP = -0.0204 (PO2/FiO2 index) + 15.678; APRV: PEEP = -0.0092 (PO2/FiO2 index) +14.889.  Conclusion:  the evolution of the critical patient with COVID-19 is determined mostly by the invasive mechanical ventilation; but we did not find evidence enough to recommend one or the other ventilation mode. The success stands in knowing accurately the characteristics of the ventilator, the ventilation modes and the patient.]]></p></abstract>
