Hyperventilation. How fast can someone pass out if hyperventilating?

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. ...Read more

In dance class, I really felt like I might pass out. I was Seeing spots, hyperventilating, & had to sit. Is this a serious Zoloft (sertraline) effect? I am worried.

In dance class, I really felt like I might pass out. I was Seeing spots, hyperventilating, & had to sit. Is this a serious Zoloft (sertraline) effect? I am worried.

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. ...Read more

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. ...Read more

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. ...Read more

Many panic episodes are not triggered by a situation or thought, and in such cases, people usually respond well to treatment with fast-acting benzodiazepines such as alprazolam. If panic is brought about by a situation or thought (s), then cbt may help in lieu of (or addition to) medication. ...Read more

I have difficulty catching breath. Could this be due to hyperventilation?

If one hyperventilates while at rest, it can indicate either pulmonary disease, heart disease, central nervous system disorder, anemia, or anxiety. All of these situations should be evaluated by a physician or other provider. ...Read more
