摘要: To improve ventilation monitoring during direct laryngoscopy, we have developed a high frequency jet ventilator which allows the aspiration of tracheal gas for carbon dioxide analysis (PtCO2) through injector after stopping ventilator. In 41 patients undergoing PaCO2 and PtCO2 were measured simultaneously under general anaesthesia. correlated significantly (r = 0.88), but underestimated by 0.84 (SD 0.72) kPa. The arterial to PCO2 difference was influenced airway obstruction.
