Questions and Answers

What is the value of urgent CPB in patients with sustained respiratory arrest or obstruction?

It can be life-saving in young patients with treatable pathology such as mediastinal lymphadenopathy (correct)
It is not recommended for patients with tracheal obstruction
It is only effective in patients with mild supra-glottic edema
It is primarily used for elderly patients with respiratory issues

When is initiation of femoro-femoral CPB considered as the only safe interim procedure?

In cases of mild supra-glottic edema
In patients with upper respiratory tract infections
Prior to controlled tracheotomy to secure an airway (correct)
After successful endotracheal intubation

What can mediastinal tumors do to major airways?

Expand major airways to prevent airway obstruction
Have no impact on major airways
Compress major airways to the extent that even mild supra-glottic edema can result in complete airway obstruction (correct)
Cause mild supra-glottic edema

Study Notes

Cardiopulmonary Bypass (CPB) and Airway Obstruction

Urgent CPB is valuable in patients with sustained respiratory arrest or obstruction.
Femoro-femoral CPB is considered the only safe interim procedure when initiation is necessary.
Mediastinal tumors can compress major airways.
Mild supra-glottic edema can result in complete airway obstruction in pediatric patients.
The primary purpose of femoro-femoral CPB is to provide temporary circulatory support.
