This covers fainting (syncope) not associated with seizures. A person who faints from a seizure will have jerky movements or will stare into space; Diagnoses and Treatments – Head – Brain – Seizures.
Fainting can be caused by a number of things, e.g., ASR, dehydration, low blood sugar.
Unless there is a serious underlying problem, most people will regain alertness shortly.
If the patient feels that he/she is going to faint before it happens, have them sit down and put their head between their knees.
If you see them fainting, gently lower them to the ground, preferably on their back.
Do a critical assessment and treat as needed, e.g., CPR, direct pressure to wounds; Must Read – Immediate First Aid – Critical First Aid.
If there is no serious underlying problem:
Cool the patient if hot,
Fresh air.
Loosen constrictive clothing.
Lie patient flat on his/her back and raise their legs 60 cm above their heart/head.
Slowly sit the patient up when ready.
Eat and drink when alert.
Continue to rest until strength returns.
Assess for other injuries, e.g., concussion from fall.
