Background: Ion mobility spectrometry (IMS) allows for online quantification of exhaled propofol concentrations. We aimed to validate a bedside online IMS device, the Edmon , for predicting plasma concentrations of propofol in normal-weight and obese patients.
Methods: Patients with body mass index (BMI) >20 kg/m scheduled for laparoscopic cholecystectomy or bariatric surgery were recruited.
