    Thank you for this video. I was wondering about what the effects of too much CO2 and too little CO2 and the effects on the human body buffer system and BANG - This. Again, thank you for this video. It was excellent. Keep on with the great videos my good man.

    Very thorough and helpful vid! The example to treat hyperventilation by using a paper bag is good for understanding but should never really be done (at least that's what i'm learning). If the hyperventilation/alkalosis is a result of overcompensation due to metabolic acidosis then giving the person a paper bag to breathe into could drop their pH dangerously low. Although, I suppose if the hyperventilation is definitely caused by anxiety then it could be useful.

    If CO2 is increased and the equalibrium shifts to the right (producing more H+), then shouldn't bicarbonate also increase by the same rate?
    If so, then doesn't that result in no overall change in pH? as opposed to a lower pH?

    • @V1P3r4

      Exactly my question! I am still looking for a response for like 2 days ago.

    • @hrperformance
      @hrperformance 5 років тому +1

      @@V1P3r4 I think (but not 100%) on this: pH is literally just to do with [H+] (concentration). So regardless of negative ions present in a solution (and therefore overall charge), pH is only concerned with the concentration of free H+ in a solution.
      I could be wrong but hopefully not XD. I'm sure we will find out one day Filip! haha

      @@hrperformance LOL, you're missing the point of your own the question--Shifting of that equilibrium from CO2 to H+ produces an equimolar amount of bicarb as well, so he's asking why wouldn't that simply buffer the H+ produced and thus have no net effect on pH. IOW why would increasing PCO2 produce acidosis at all??

    Hey, sorry, but how come people actually develops acidosis after a while they are hyperventilating? Like in an asthma attack? I know they initially are alkalemic for the reason you explained, but from what I studies I know that they eventually develop acidosis and I really do not understand how this works!

    Great video. But one thing bothers me:
    Hyperventilation: decrease of CO2 => decrease of H+ => increase of pH
    Similar for hypoventilation. That just doesn't make sense to me, since pH depends on [H+]

    • @nathalieb3879
      @nathalieb3879 8 років тому

      +Vitaly Borisov The pH can be calculated using [H+] which is the concentration of H+, namely pH= - log([H+]). Since it's a negative logarithm, the pH will be higher with a lower concentration and therefore increase if the concentration decreases.

    • @chukksy
      @chukksy 8 років тому

      Nathalie B
      Ah yeah. My bad. Got a bit confused. Makes total sense. [H+] goes down, [OH+] goes up and pH also goes up.

    can someone please for the love of god explain this to me....
    i understand why increase CO2 would result in an overproduction of H+, however, does it not also result in an over production of bicarb? and wouldn't the 2 just cancel each other out since H is acidic and bicarb is alkaline?

    • @saivizzaal9105
      @saivizzaal9105 8 років тому +1

      In blood carbonic anhydrase is unavailable to catalyst conversion of proton and bicarb to carbonic acid.. The bicarbs by means of chloride shift is taken back by the rbcs so the co2 is exhaled out..hence neutralisation of h+ by bicarb can occur only in presence of CA which is not available in blood.. I think this is one of the reasons

      Brent Wheeler actually there is a ratio in our body between carbonic acid and carbonate ion, in healthy state a ratio of 1 part carbonic acid to 20 parts bicarbonate provide a noramal pH. so when co2 incresed the carbonic acid increses and to maintain the healty ratio the 20 bicarbonates used to neutrilize the effect of 1 carbonic acid and the H+ incresed and the pH goes down. If you want i can make u understand by a video.

      @@anilmandiwal8467 Wow, that makes absolutely no sense. 1 mole of carbonic acid breaks down to 1 mole of H+ and 1 mole of bicarb. That's just basic chemistry. So from one mole of carbonic, how the hell does it take 20 moles of bicarb to buffer 1 mole of H+???
