UNLABELLED Intraoperative paradoxical air embolism may occur even if a patent foramen ovale (PFO) is excluded by contrast transoesophageal echocardiography (TEE) under 20 cm H2O positive airway pressure. It is questionable whether the combination of PEEP and ventilation with a large tidal volume increases the sensitivity of contrast TEE in detecting a PFO. METHODS Eighty healthy patients (ASA status I, II) scheduled for surgery in the supine position and ranging from 25 to 72 years of age… CONTINUE READING
