Individual and combined effects of chemical and mechanical power on postoperative pulmonary complications: a secondary analysis of the REPEAT study

open access: yesAnaesthesia, Volume 80, Issue 12, Page 1510-1518, December 2025.
Summary Introduction Intra‐operative supplemental oxygen and mechanical ventilation expose the lungs to potentially injurious energy. This can be quantified as ‘chemical power’ and ‘mechanical power’, respectively. In this study, we sought to determine if intra‐operative chemical and mechanical power, individually and/or in combination, are associated ...
