Total carbon dioxide level "32" 5 different times.. Normal is 22-29? These where blood test.... Is this worrisome? Docs?

No: If your are able to exercise, have good stamina, and good appetite without eating artificial foods/supplements, then I would not have you worry about. I'm sure the renal function and glucose are normal. ...Read more

I am confused about carbon dioxide levels in the blood?

I am confused about carbon dioxide levels in the blood?

Confused?: Co2 is dissolved in the blood. It is related to the ph of the blood. The higher the co2, the lower the ph and visa versa. When the co2 goes up, one breaths more rapidly to blow off the co2. The co2 in the blood comes from the metabolism of cellular mechanisms and is exchanged for oxygen in the lungs. Any more questions? ...Read more

What can cause a low carbon dioxide level in a blood test?

What can cause a low carbon dioxide level in a blood test?

Loss or acidosis: Loss of carbon dioxide (as carbon dioxide) can occur in anything that makes you breathe heavily for a long period of time. (being on a ventilator as one example). Loss through the kidney with diuretics sometime. Mostly, CO2 is in the form of bicarbonate. This is removed by acidity which occurs in serious organ failure (sepsis, kidney failure, etc.) ...Read more

How can hyperpnea affects partial pressure of carbon dioxide and oxygen levels in the blood?

How can hyperpnea affects partial pressure of carbon dioxide and oxygen levels in the blood?

Hyperpnea/tachypnea: The rapid breathing will blow out co2 and lower its level in the blood. This may or may not affect the o2 level depending on the cause of the tachypnea. ...Read more

What changes can you expect in the levels of blood oxygen and carbon dioxide in a patient who breathes rapidly and deeply for a prolonged time?

What changes can you expect in the levels of blood oxygen and carbon dioxide in a patient who breathes rapidly and deeply for a prolonged time?

Hyperventilation: Many athletes may "oxygen-load" their blood just prior to a race by doing this. Breathing rapidly will draw in more oxygen and "load up" the red blood cells' hemoglobin, and at the same time empty out more carbon dioxide than usually would be. You have to be careful doing this, because it will throw off your body's acid/base balance and make you dizzy or pass out! ...Read more

Carbon dioxide level is high in my mother's blood & she is using bipap machine. Is there any medicine for this so that she does not have to use bipap?

Carbon dioxide level is high in my mother's blood & she is using bipap machine. Is there any medicine for this so that she does not have to use bipap?

Not likely: High serum co2 suggests chronic hypercarbia for which bipap is appropriate. No inhalers will dramatically improve hypercarbia over the short term. An alternative explanation for high serum co2 is severe metabolic alkalosis from vomiting or excessive diuretic use. An arterial blood gas can aid in telling the difference. ...Read more
