ABSTRACT
A "cannot-ventilate, cannot-intubate" situation is critical. In difficult airway management, transtracheal jet ventilation (TTJV) has been recommended as an invasive procedure, but specialized equipment required. However, the influence of upper resistance (UAR) during TTJV not clarified. The aim this study was to compare using a manual ventilator (MJV) and oxygen flush device anesthetic machine (AM). We made model lung offering variable UAR by adjustment tracheal tube size that can ventilate through 14-G cannula. measured side flow due Venturi effect TTJV, inspired tidal volume (TVi), expiratory time under various inspiratory times. No detected with either device. With MJV, TVi tended increase in proportion UAR. AM, significant variations changes any conclusion, influenced forward lung. choked from minimal all settings AM could deliver sufficient flow.
