Inclusion criteria was patients ≥18 years old, severe COVID 19 related ARDS, driving pressure ∆P >15 cmH2 O despite low-VT strategy, and extracorporea therapies not available. MTH was induced with a surface cooling device aiming at 34°C. MTH was maintained for 72 h, followed by rewarming of 1°C per day. Data were shown in median (interquartile range, 25%–75%). Mixed effects analysis and Dunnett’s test were used for comparisons. Seven patients were reported. Ventilatory load decreased during the first 24 h, minute ventilation (VE) decreased from 173 (170–192) to 152 (137–170) mL/kg/min (P = 0.007), and mechanical power (MP) decreased from 37 (31–40) to 29 (26–34) J/min (P = 0.03). At the end of the MTH period, the VT, P, and plateau pressure remained consistently close to 3.9 mL/kg predicted body weight, 12 and 26 cmH2 O, respectively. A combined strategy of MTH and ultraprotective mechanical ventilation (MV) decreased VE and MP in severe COVID-19-related ARDS. The decreasing of ventilatory load may allow maintaining MV within safety thresholds.enAtribución-NoComercial-CompartirIgual 3.0 Chile (CC BY-NC-SA 3.0 CL)COVID-19HypoxemiaMild hypothermiaLung protective ventilationAcute respiratory distress syndromeArticlehttp://orcid.org/0000-0003-4763-074X10.4103/tjem.tjem_339_22
