saddled PE and hemodynamic

Q: Saddle Pulmonary Embolism (PE) is usually associated with hemodynamic instability?

A) True

B) False

Answer: B

Although saddle PE is expected to cause hemodynamic instability, less than one-fourth of patients experience this. Moreover, mortality from saddle PE is only 5 percent if a patient receives care at time. 

The total frequency of saddled PE is only around 5 percent.
