Hyperventilation. How fast can someone pass out if hyperventilating?

Varies: This varies from person to person ranging from fast to not being able to fully pass out. When one hyperventilates, the arterial carbon dioxide level drops, this causes a physiologic decrease in blood flow to the brain, and depending on the person, they may pass out due to decreased blood flow similar to a fainting episode. Don't try this alone or while standing.

Anxiety: Sounds more like a panic attack. When you start to hyperventilate your body blows off carbon dioxide and that can cause your blood vessels to constrict. That causes the feeling of "passing out", visual spots and weakness. The mechanism is real. Continue your activities. Dance is excellent for exercise and relaxation. Stick with your meds. If symptoms are recurrent let your doctor know.

Can hyperventilating from breathlessness after running fast cause you to breath in more pollution? Dangerous if run for a long time? Car came v close

Pollution: Particulates that deposit in the lungs are uniformly distributed for the most part with local spikes (smoke etc).The larger the volume of air cycled through the lungs the larger the volume of undesired exposure, Beware

I ran up the stairs and was breathing fast pretendin to be hyperventilating and I had distorted vision for 30 seconds didn't feel faint is that normal?

Hyperventilating: PremM ~ yes hyperventilating blows off CO2 and the low pCO2 in the blood disturbs calcium metabolism and you can get cramps in the long muscles and parasthesiae or numbness sandf tingling in the perifery. If you continue you pass out. Treatment. Get a brown paper BAG and put it over mouth and nose and re-breath your own breath and it corrects.

Complex: Hyperventilation at night can be related to stress, congestive heart failure, drugs taken at bed time, other. So, wide range of possibilities. Lorazepam is a sedative. If taken for stress, and hyperventilation occurs with dreams then anxiety might be the relationship. A formal sleep study could provide diagnosis by seeing timing, heart pattern, and associated details.

How/why does hyperventilation sometimes lead to syncope?

Carbon dioxide: This is the main "driver" for us to breathe. Co2 levels in the brain cause the respiratory center to signal breathing. When you hyperventilate you blow off a lot of co2 and the brain senses no need to breathe. Another driver is oxygen but since your o2 levels be high, the brain senses you have enough o2.

Hyperventilation, what size paper bag?

Hyperventilation, what size paper bag?

Whatever: Can you still find a paper bag? The idea is to build up co2 levels so the smallest bag that will cover both your nose and mouth and hold a good breath would work. But a big bag would probably work almost as fast if that's all you have. Plastic would not be a good idea.

How can hyperventilation treat hyperkalemia?

Acid-base: Hyperventilation drives the carbondioxide from the lungs, so you develop respiratory alkalosis which causes hypokalemia (low potassium).If someone has hyperkalemia and hyperventilation, they probably have some other underlying cause like metabolic acidosis which could be due to several reasons like severe diarrhea, kidney failure, infection. These are only few and one should consult nephrologist.
