As a matter of fact, CPR will not be initiated unless the patrient's breathing or heart stops, which implies that patient may die if CPR is not started immediately.
One definitely knows patient has fainted by looking at & talking to them and shaking their shoulders!!!
Anxiety and emotional stress, orthostatic hypotension are the most common causes of syncope

I passed out due to severe stomach pain and my husband said i was making choking sounds and could not breathe. Should I be concerned. This isn't the first time this has happened.
