摘要: a b s t r c Objective: Supraglottic airway devices (SGDs) are often used as an alternative to endotracheal tube (ETT) during cardiopulmonary resuscitation (CPR). SGDs can be inserted 'blindly' and rapidly, without stopping compressions. These utilize pressurized balloons direct air the trachea prevent esoph- agus insufflation. We hypothesize that use of SGD will compress carotid artery decrease blood flow (CBF) CPR in pigs. Methods: Ventricular fibrillation (VF) was induced 9 female pigs (32 ± 1 kg) followed by 4 min then performed continuously for 3-6-min intervals. During each interval, ETT first 3 min, (King LTS-D TM
