1
Q

Outline the pros and cons of an SGA as compared with an ETT or an OPA.

A

Pros:
Improved airway + ventilation management than OPA.
Lower aspiration risk than OPA.
Easier and quicker to insert than ETT.
Cons:
Lower level of aspiration protection than ETT.

Q

Which patients are likely to have higher airway pressures, and what do these patients require?

  1. Pregnancy
  2. Morbid obesity
  3. Decreased pulmonary compliance (pulm. fibrosis)
