Definition

Fainting, or syncope, is a sudden, temporary loss of consciousness.

Healthcare professionals often use the term ‘syncope’ when referring to fainting because it distinguishes fainting from other causes of temporary unconsciousness, such as seizures (fits) or concussion. In most cases of fainting, the person who has fainted regains consciousness within a minute or two.

However, less common types of fainting can be medical emergencies. If a person who has fainted does not regain consciousness within two minutes, then medical assistance should be sought immediately and the patient placed in the Recovery Position.

Vasovagal Syncope

Vasavagal syncope is a form of fainting related to the temporary malfunction of the autonomic nervous system, which regulates heart rate and blood pressure, in response to a trigger, such as the sight of blood or extreme emotional distress. When heart rate slows, blood pressure drops, and the resulting lack of blood to the brain causes fainting and confusion.
