co retention

How do you know if you're retaining co2? Does a Dr tell you? My Dr told me to keep my 02 between 90-95. I have the oximeter on my finger constantly. Anxious whether I fall above the limits or below the limits set for me.

  1. Hi katw, and thanks for your post and question - it's a good one! Generally speaking, the signs and symptoms of carbon dioxide (CO2) retention, can vary from patient to patient. These can range from feeling tired and confused, to dizziness and experiencing an increased breathing rate. However, these few signs I've mentioned should not be an indication to any of our readers that these are indicative of a rising CO2 for any of us. This truly is something to be discussed with one's own doctor, especially if there is an individual concern.
    If your doctor advised you to maintain the oxygen saturation level between 90%-95%, that is what you should be monitoring. The pulse oximeter, as you well know, will help you to do this.
    There is a type of chronic obstructive pulmonary disease (COPD), in which the patient chronically retains CO2. This is somewhat different than the question you posed here. To be thorough, though, I did want to mention it. Is this what your concern is, katw? Has your doctor spoken to you about this type of COPD in your particular case?

    1. Thanks for the reply. My Dr has not told me I retain co2, I was under the impression that getting my 02 above the 95 limit he gave me would contribute to co2

      1. Hi again, katw - thanks for your prompt reply. If the doctor has not mentioned CO2 retention in conjunction with using oxygen in your case, there should not be an issue. However, I do understand that some patients think maintaining the oxygen saturation between 90%-95%, might have an effect on one's carbon dioxide. (That may apply to folks who have the type of COPD in which they chronically retain CO2).


        I would suggest, if you truly have this concern (and I am not questioning it!), you may want to reach out to your physician. Your doctor will know for sure based on your particular level of disease. He/she will be able to guide you accordingly. Remember, this all began when the doctor suggested you keep the oxygen saturation level in the range of 90-95%. He/she will be able to put your mind at ease.
        For safety reasons, I can only speak generally here. If this helps you to clarify your concerns with your own doctor - that would be the most prudent approach for you.
        What do you think, katw?
