Respiratory Acidosis

Respiratory acidosis is a medical emergency in which decreased ventilation (hypoventilation) increases the concentration of carbon dioxide in the blood and decreases the blood's pH (a condition generally called acidosis). Carbon dioxide is produced continuously as the body's cells respire, and this CO2 will accumulate rapidly if the lungs do not adequately expel it through alveolar ventilation. Alveolar hypoventilation thus leads to an increased PaCO2 (a condition called hypercapnia). The increase in PaCO2 in turn decreases the HCO3−/PaCO2 ratio and decreases pH. Terminology[edit] Acidosis refers to disorders that lower cell/tissue pH to < 7.35. Acidemia refers to an arterial pH < 7.36.[1] Types of respiratory acidosis[edit] Respiratory acidosis can be acute or chronic. In acute respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range (over 6.3 kPa or 45 mm Hg) with an accompanying acidemia (pH <7.36). In chronic respiratory acidosis, the PaCO2 is elevated above the upper limit of the reference range, with a normal blood pH (7.35 to 7.45) or near-normal pH secondary to renal compensation and an elevated serum bicarbonate (HCO3− >30 mm Hg).

    The last few days, I have noticed this gross skunk like odor that is coming from me, but I can't figure out where. I sniff my underarms, but it's not coming from there cuz all I smell is my deodorant. The odor is there for a moment then gone but it's driving me bonkers and I spray more body spray than ever because I'm afraid of driving people away from me. Any suggestions as to what could be causing this? I drink tons of water to take care of the keto breath and that seems to work fine. But this other odor!

    Could it be coming from your nose.....could you have a sinus infection?

    I too get this horrible odor, but I seem to be the only one who notices! My friends and coworkers swear that the only thing that stinks on me is my attitude! I can taste it too, and it drives me bonkers!!!
