Signs & Symptoms of Syncope
Feeling of warmth or flushing (flushed)

Postural Hypotension
Emergency can occur when pt assumes an upright position too quickly.

Postural hypotension is different than syncope.
The duration of unconsciousness is very brief, usually lasting only seconds to minutes.
Signs and symptoms include:
*Low blood pressure
*Altered state of consciousness to possible loss of consciousness
Responding to Syncope
Place the patient in a subsupine position with the head lower than the feet.
Known as Trendelenburg position.
Have an ammonia inhalant ready to administer by waving it under the patient’s nose several times.
For a pregnant woman:
While in a supine position, the pregnant patient may feel dizzy or lightheaded and may faint
Results from pressure of enlarged uterus on abdominal veins
In contrast to the procedure for postural hypotension, the pt should be turned on her left side
