  Which of the following explains this finding?
  a. Pneumothorax.
  b. A dislodged mucus plug is obstructing the endotracheal tube.
  c. Acute bronchospasm.
  d. Movement of the endotracheal tube.

Question 2

  b. Asynchrony
  c. Inadequate ventilatory support
  d. Inadequate FiO2

Answer to Question 1

ANS: D
Another common problem with endotracheal tubes is movement of the airway into the oral phar-ynx or movement into the right main stem bronchus. Both of which can be life threatening alt-hough movement into the oral pharynx, essentially extubation, is the most life threatening. In some situations the airway can be moved back into the trachea, in others reintubation is neces-sary. If this occurs adequate ventilation is generally impossible. Airway pressures and tidal vol-umes rapidly decrease and there is frequent gas leakage from the mouth and nose. It is thus im-portant to determine at each patient-ventilator assessment the location of the endotracheal tube.
