Pharyngeal cooling cuff (left) and circulator (right). Physiological saline (5 °C) is initially supplied to the oesophageal cuff through the inflow tube, where the temperature is continuously monitored, and subsequently fills the pharyngeal cuff before being discharged through bilateral outlets. The bilateral outlets are connected to an outflow tube, where pressure is continuously monitored. According to a pilot study, intra-cuff pressures at the oesophageal and pharyngeal cuffs were 8 cm H2O and 6 cm H2O higher than the pressure monitored at the outlet tube, respectively. The intra-cuff pressure at the pharyngeal cuff was controlled at 50 cm H2O. The cuff is made from vinyl chloride, has passed biological safety tests, and tolerates up to 200 cm H2O of intra-cuff pressure
