how does increased and decreased ventilation affect your oxygen, cabon dioxide and ph?
98888
Assuming you're talking about in the body: increased ventilation increases the amount of oxygen in your alveoli (lungs) and decreases the amount of CO2, the pH is buffered under normal circumstances by bicarbonate but more CO2 would lower the pH. Decreased ventilation gives the opposite effect of the ones mentioned.\n\nHope this helps

Are you talking about the positive end expiratory pressure (PEEP)? The mean airway pressure or the alveolar pressure in the lungs? All have slightly differing values. These are usually measured in mm Hg or cm H2O. All airway gas exchange is performed through passive diffusion in the aveoli of the lungs. Air must be at normal atmospheric pressure at 760 mmHg for most efficient gas exchange to occur. \nAir at higher altitudes has lower pressure, so one must work harder, in physiological terms to enable the diffusion of oxygen. usually for mountain climbers, this means increased rates of respiration. At high enough altitudes, you cannot get enough oxygen with respiratory effort and you pass out from hypoxia.\nAt higher pressures (underwater) gas diffusion occurs more quickly, and you must use less oxygen to get the same blood oxygenation level as you wold at sea level. This is why divers use a NOx mix, and not pure oxygen underwater, if they did, they would develop oxygen narcosis very quickly.

Within limits,as temperature increases,so does the amount of O2 released from the hemoglobin.Heat is a byproduct of the metabolic reations of all cells and the heat released by contracting muscle fibers tends to raise body temperature.Metabolically active cells require more O2 and liberate more acids and heat.The acids and heat, in turn, promote release of O2 from oxyhemoglobin(oxy binded with hemoglobin in blood).\n\nSo, increased in temperature caused the rate of respiration to increase too.Because O2 tends to be released from the hemoglobin compared to when the weather is cold.This explain why during fever,a person will breath faster than normal person.\nIn contrast,during hypothermia(lowered body temperature) cellular metabolism slows and the need for O2 is reduced,and more O2 remains bound to hemoglobin.\n\nPlease check my grammar too.Im sux with my grammar coz English is my 3rd language.So, please check it.Hope this helps ya!

Enzymes tend to work best within narrow pH and temperature ranges, specific for the enzyme in question. Raising the temperature to 100 C would most likely denature the enzyme and render it inactive.\n\nFor your interest, carbonic anhydrase is the catalyst for CO2 exchange in the lung during respiration. It works best at about body temperature and pH of 7.35.

increase in acidity....\n\nread your textbook, PLZ

When you hyperventilate, you breathe out excess carbon dioxide.\n\nWhen you breath out excess carbon dioxide, the pH of your blood gets affected (it becomes more basic).\n\nBy breathing into a paper bag, you breath the lost carbon dioxide back into your system, thus preventing a severe disruption in your blood's pH.\n\n-random physician

how indepth do you want this?\n\nbasically caused by a pressure differential in your lungs (the diaphragm inflates the lungs)...the oxygen molecules are forced through alveoli (sacs) into the bloodstream because fo this pressure differential...at the same time...Carbon Dioxide flows in the opposite direction from the blood to teh lungs to be exhaled...the oxygen attaches itself to hemoglobin..which is found in the red blood cells...and is then transported throughout the body by the heart (arteries pump blood away from the heart to teh body..veins take the blood back)\n\nhope thats good enough lol

Yes,CO binds to mitochondrial cytochrome oxidase and impairs oxidative phosphorylation and causes cell damage.So CO adversely affect respiration in plants.Carbon monoxide increases the amount of other greenhouse gases (methane), and eventually oxidises into the greenhouse gas, carbon dioxide. Greenhouse gases are linked to global warming.

yes Le chatelier's principle could help you, there is increase in acidity of the body due to accumulation of metabolites in the blood ( the heart is not working properly so the wastes of the cells specially acids do accumulates) so sodium bicarbonate is given to make the equilibrium\n+H + H2CO3 --------->  H2O + CO2\nthe water gets out by kidneys or throught respiration and CO2 gets out  through respiration!

Oxygen deficiet is where there is little amount of oxygen in the blood! it is also called hypoxia. it can occur for so many several causes such as impaired breathing or CO poisoning or so on.\noxygen debt is a state of continuous increased breathing even after you stopped an exercise!\nduring exercise your body uses all the oxygen that was stored in the myoglobin of the muscle. during exercise there is increased breathing to compensate the metabolic requirements. after you suddenly stop the exercise your breathing still high for some time then it decrease to normal.. this continuous high breathing is due to oxygen debt.. the body try to get the oxygen which it has taken for the myoglobin back!

Um, I think one would be the CO2 build up causes the lungs to breathe, in a nutshell.

Good info Klaus, but you mostly are discussing decompression, in which dissolved gases (usually nitrogen) bubbles out of the blood when going from high to low pressure-Not the reason oxygen is toxic.  The blood requires a certain pressure of oxygen, in other words, and certain number of molecules.  The normal concentration of oxygen in the atmosphere is about 21%, which of course is about perfect.  If you are in an environment that has twice the pressure, you require oxygen at half the concentration, or about 10%.  Its still the same number of molecules total, just a lower concentration.  Clearly, if you are in an environment of 10X the pressure compared to sealevel, you only need a concentration of oxygen of about 2%...again, its still the same number of molecules of oxygen, but because of the greater pressure, there is a lot more total gas molecules present.  Oxygen is a highly reactive molecule, and causes (obviously) oxidation...such as rust on iron.  In the body, this is a toxic effect-More to the point, though, is that the body requires a certain amount of carbon dioxide to maintain the proper acid-base balance.  If far too much oxygen is given, it swamps the ability of hemoglobin to bind CO2, thus causing acidosis-the acidification of the blood.  So, the deeper you dive, the lower *percentage8 of oxygen you require (though again, its the same *amount* of oxygen)- the oxygen is replaced by the most inert gas that can be obtained-helium usually.

you defintly have something going on with your metabolic workup. your HCO3 is very low giving you a compensated metabolic acidosis. Meaning that your paco2 is low compensating for your hco3 being low. co2 is acidic and the hco3 is a base normal values for pco2 is 35-45 and hco3 is 20-28. your body will try to compensate by increasing each of those numbers to get a normal ph in the body. with a hco3 like that you probably have been short of breath??? thats how your body gets the pco2 to decrease (hyperventilate) heavy breathing will give you a increased po2

Oxygen enters the blood in the lungs, where is binds to hemoglobin (which has a strong oxygen-binding affinity). Hemoglobin travels through the blood until it reaches the blood vessels. Once blood reaches the muscles, the carbon dioxide produced by the muscles enters the blood in the form of carbonic acid. The carbonic acid lowers the blood pH, which lowers the affinity of hemoglobin to bind oxygen, releasing large amounts of oxygen into the working tissues of the muscle.

Breathin enables cellular respiration to continue.  Your body tightly regulated level of dissolved blood gases (i.e. CO2 and O2) by regulating your breathing rate.  In doign so it is able to keep these values within acceptable limtis and maintain homeostasis.

PO2 must drop below 60 mm Hg for stimulation of peripheral chemoreceptors. Up to a PO2 of 60 mm Hg, Hemoglobin is still substantially saturated with O2 and adequate amounts of O2 can be delivered to tissues and the brain. Also, when PO2 drops from 100 - 60, usually there is also increased PCO2 levels. So, ventilation is usually increased due to response of central and peripheral chemoreceptors to increasing PCO2 levels.

It depends on where CPR take place. \nIf it is happening outside of hospital, it's impossible to get 100% oxygen. \nAnd if a person breathes 100% oxygen for long time,it can damage your body. \nAnd under some situations, you need to give low oxygen concentration to keep patient alive, e.g., in some chronic obstructive pulmonary disease(COPD) patients., high concentratin oxygen can kill them.\n{Carbon dioxide in the air can help to stimulate the respiratory center of the brain (which is life saving for some COPD patients). Because they have low blood oxygen for long term,so their respiratory control center in the brain no longer react (to stimulate breathing) to low blood oxygen. Only increase in the blood carbondioxide can stimulate their respiratory control center.}\nSo,100% oxygen is not the best for all.
