What basically happens when you faint and lose consciousness, and pass out?

Question

I passed out and I don't remember how it happened....Can someone explain to me what happens when you lose consciousness? I asked the neurologist and all he said was, my brain was lacking blood and oxygen since I have low blood pressure. I don't get it though. Does your brain stops sending message to stay conscious? Is it like falling asleep suddenly?

Answer 1

The loss of conciousness means that all of your brain shuts down temporarily except for the part that keeps your organs working. When you are unconcious, your brain does not respond to sensations of sight, sound, pain, touch, movement, or temperature. When you sleep, you brain is very active and all of the senses still respond if the stimulus is large enough to wake you.

Answer 2

I fainted once in the bathroom and my doctor told me it was because since it happened right when I woke up from bed my brain was still tired and needed to rest in order to organise all the infromation. It's like suddenly falling asleep but you forget what happened before and during the process. Just try to stay relaxed and eat really healthy and you should hopefully do fine.

The solutions that concentrate on what the guy has OD'd on are correct on the ball. the first problem that an EMT will do with an subconscious man or woman is verify respiratory and pulse. Then, secondary evaluation for bruises, cuts, scrapes, know-how (e.g. student verify.) There are sorts of ODs. Sedative/hypnotic/depressants are all respiratory hazards once you OD. A nurse, physician, or paramedic can do a discomfort try on you and fail to have you ever wake. that means that your frightened device isn't responding because it really is going to. in case your respiratory is likewise slowed, it means that the depressant is in the route of your mind stem, that's indicative of severe chance. Aspiration, or fluid on the lungs, is between the most elementary motives of death for someone who isn't responding to standard stimuli. once you're really sedated, your body isn't reacting to exterior effect - it truly is why human beings opt to quickly previously they are placed less than in surgical operation. dropping conciousness is also the end results of more desirable intracranial (interior your head) rigidity. actual motives of unconsciousness and really coma might want to potential to be truly risky. while an OD on drugs might want to be counteracted through an antagonist, typically the reason of a bodily triggered coma needs time-comfortable surgical operation. it really is uncommon to come back out of an prolonged coma brought about through a actual source with out some damage, through break to mind tissue and next lack of oxygen. in short, quick interest from an EMT for a drug OD ability you're probable not searching at a nasty result - truly if the guy wakes up on their own, though there might want to be some damage from hypoxia (lack of oxygen) if the guy is respiratory shallowly, blue, etc. maximum EMTs would attempt to substantiate what the drug is and then if conceivable problem an antagonist. that would want to probable wait until eventually the well-being middle. Blood checks, in the journey that they don't recognize offhand depending on the priority or ecosystem. in the journey that they recognize that's an OD, they probable does not supply epinephrine as a stimulant would were the reason of a give way through odd heart rhythm. ODs are hardly ever going to give up the middle except that's polydrug abuse or secondary to respiratory complications.
