faint for many reasons but the question is always should I call 911
The first decision point is "does the person lose
consciousness?". After they they can they respond to you? If not
you should call 911 immediately and check their breathing and if
necessary start CPR.
If they are conscious then we need to determine what happened. There is always a reason for the fainting. One of the easiest ways to determine this is asking SAMPLE questions.
Signs and symptoms
Past Medical History
Events leading up to the fainting
By gathering this information you should be able to determine what caused the fainting. If not then the person should be checked by a Physician. If the person has a serious medical condition then they also should be seen by a Doctor.
Remember, when in doubt call 911.
