COPD patient...give low flow O2 to prevent respiratory alkalosis?

  1. Does giving low flow O2 prevent respiratory alkalosis in a COPD patient? I think it would prevent respiratory alkalosis because giving too much O2 would be hyperventilating the patient.

    giving low 02 will not prevent respiratory alkolosis. nor does giving high 02.
    high 02(for example 15 lpm on a tnrb) would "knock out" the copd 02 drive. that would cause respiratory acidosis.
    respiratory alkolosis is hyperventilating. they have enough 02 so have the person/patient breathe in a paper bag and/or 6 links of corruagated tubing. this would(hopefully) normalize thier breathing pattern
    in all honesty, how fast, the depth and quailty of a person's rr would dictate the need for the 02 itself.:spin:

    Informative link re: COPD. Under the Treatment section, there is an interesting discussion of the myths that often surround hypoxic drive.
