In a prospective, randomised-controlled trial, morbidly obese patients with normal lung function using post-extubation continuous positive airway pressure (CPAP) achieved an improved pulmonary oxygenation; however, oxygenation did not persist after termination of CPAP. The findings were presented by Dr Felix Girrbach (University Hospital of Leipzig, Germany) [1]. The rationale behind the study, Dr Girrbach explained, was that mechanical ventilation with individualised positive end-expiratory pressure (PEEPIND) in combination with continuous CPAP support in the initial hours following extubation is associated with better oxygenation compared with the use of PEEP alone. In this study, 46 participants with a BMI of >35 kg/m2 who were scheduled to undergo bariatric laparoscopic abdominal surgery were ventilated with PEEPIND, which was defined as “the PEEP value with the lowest regional ventilation inhomogeneity as de...
