• Background: If the endotracheal placement of a nasal advanced tube fails, ventilation via this tube could bridge the time until a fibreoptic bronchoscope is available. This study investigates the efficiency of ventilation via a tube resting with its tip in the pharynx near the glottis. Methods: In 20 patients respiratory data during ventilation via a pharyngeally placed tube were recorded by means of pulse oximetry, capnometry and side‐stream spirometry. Results were compared with those measured previously in the same patients during conventional facemask ventilation. Results: Oxygen saturation and end‐tidal carbon dioxide concentration remained unchanged using ventilation via facemask (SO2 98.5±0.9%, FECO2 4.5±0.7 vol%) or pharyngeal tube (SO2 98.6±0.7%, FECO2 4.8±0.4 vol%). No significant differences were found between the two groups with regard to peak airway pressure, tidal volume leakage, compliance and resistance of the respiratory system. Conclusions: Our results suggest an effective ventilation and oxygenation via a tube placed with its tip in the pharynx. This technique may be helpful during difficult and prolonged nasal intubation.
