Usually: It is the result of the medication given to drift you off to sleep to facilitate the intubation. They are vasodialators as well as amnestic anesthetics. The drop in BP is usually very transient and harmless.

The act of intubation is actually very stimulating and will usually increase blood pressure. The drop in BP is caused by the anesthetics

Increased bp: In general intubation is very stimulating. In fact it usual to employ methods to control blood pressure during intubation. After intubation if a patient is not under general anesthesia patients are usually given some form of sedative so they tolerate being on a ventilator. So decreased blood pressure is not usual other than if it is a side effect of medications given.
