Do all nurses think ammonia capsules need to be used every time a patient gets faint?
I have fainted three times, I know what it feels like. Fainting lasts ?? a few seconds and as soon as the head goes down, blood flow goes "up" to the brain, and it is over.
Let us assume I have special powers, I know the patient is "just" fainting, vaso-vagal, no "serious" medical issue is going on. I wouldn't use ammonia.
I can see it being useful if you are walking with the patient and want to prevent a fall, but if there is not a fall, self-harm, issue I wouldn't use one. Would you?
