Respiratory Acidosis

(Video) Overview of Acid-Base Maps and Compensatory Mechanisms By James L. Lewis, III, MD, Attending Physician, Brookwood Baptist Health and Saint Vincents Ascension Health, Birmingham Respiratory acidosis is primary increase in carbon dioxide partial pressure (Pco2) with or without compensatory increase in bicarbonate (HCO3); pH is usually low but may be near normal. Cause is a decrease in respiratory rate and/or volume (hypoventilation), typically due to CNS, pulmonary, or iatrogenic conditions. Respiratory acidosis can be acute or chronic; the chronic form is asymptomatic, but the acute, or worsening, form causes headache, confusion, and drowsiness. Signs include tremor, myoclonic jerks, and asterixis. Diagnosis is clinical and with ABG and serum electrolyte measurements. The cause is treated; oxygen (O2) and mechanical ventilation are often required. Respiratory acidosis is carbon dioxide (CO2) accumulation (hypercapnia) due to a decrease in respiratory rate and/or respiratory volume (hypoventilation). Causes of hypoventilation (discussed under Ventilatory Failure ) include Conditions that impair CNS respiratory drive Conditions that impair neuromuscular transmission and other Continue reading >>

    I got out of the hospital yesterday, I had food poisoning and got admitted for Ketoacidosis. I feel a lot better now but, I'm in a little discomfort. My stomachs bothers me somewhat after I've eaten and I'm a little uneasy when I'm walking. I was in bed for a day and a half so I'm sure I'm just weak. But, did you recover right away or, did you take a day or two?

    Every time I'm in the hospital for DKA, I start to feel better around day 3. They never let me leave until day 5-7 though. :| So glad the last few times they've had wifi to watch Netflix on.

    3 days from start of IV fluids. When you get home, try to drink water instead of your usual fluids for a day or so. I find it helps get me back on track faster. Also, keep an eye on your BG a bit tighter for a few days after. The whole DKA resolution treatment and IV fluids can alter the way your BG floats (in some interesting ways) until you get back into your normal groove/routine.
