Consult a doctor immidently! I am just going to take a guess at what it MAY be, but..... (don't wanna scare you!) but it may be respetory failure. In fact, it could be a number of things! This is a tough one. I do NOT want to make the mistake of diagnosing something you may not have, so my advice-see a doctor&search ALL symptoms on internet! Do not waste time. Act accordingly!
Nearly all the time. You seldom make a conscious effort to breathe.
No, but they helped you survive. Breathing through a filter takes more effort than breathing w/o a filter. But if the filter can keep you from inhaling poisionous stuff it's probably a good tradeoff.
What are ways the body changes the way we breathe in effort to keep our levels of oxygen and carbon dioxide balanced
Airway Circulation Breathing / Respiration effort
Cheyne-Stokes respiration. It is a pattern of breathing characterized by alternating periods of deep, rapid breathing followed by periods of shallow, slow breathing or even temporary cessation of breathing. This respiratory pattern is typically observed in patients with severe brain damage or neurological disorders affecting the brainstem.
when you breath in your diaphragm muscle expands your lungs to take in air. when you breath out your diaphragm muscle pushes on your lungs to let out the air.
breathing is controlled by the level of co2 in the blood, (not due to the fact that there may be low amounts of o2), there are chemoreceptors that measure the pH level of the blood, remember that co2 can be transported in the blood as carbonic acid, thus this acid lowers the pH. if a low pH is detected, it sends nerve impulses to our brain, that stimulates us to breathe in an effort to get rid of the co2.
You don't - at least not directly. You set your pace, and your body will adjust your breathing rate to what it needs to keep itself supplied with oxygen for that level of effort. If you begin to feel shortness of breath you just have to let up on the pace until you have recovered. About the only deliberate control people might use is to breathe in synch with their steps, one way or another. In on two steps, out on one or something along those lines.
The combination of helium and oxygen, known as heliox, reduces the density of the delivered gas, and has been shown to reduce the effort of breathing and improve ventilation when an airway obstruction is present.
Your question is somewhat vague. If you are underwater, you pass out because of lack of oxygen and your organs begin to die, especially the brain. It is miraculous when someone has been underwater without oxygen for more than even a few minutes and survives without brain damage. If you are talking about holding your breath, while it is difficult to hold one's breath until they pass out it is not impossible; this is your body shutting down all nonessential systems in a last ditch effort to get you breathing again---while your will may be strong enough to get you to pass out, once you are unconscious you will breathe unless your airway is blocked.
Establish unresponsiveness,call for help,check for effort of breathing,if no breathing,give two breaths,check pulse,then 30 chest compressions if no pulse
Ventilatory assistance devices are mechanical devices that help a person breathe by replacing some or all of the muscular effort required to inflate the lungs
