Excess CO2 causes the pH of blood and other bodily fluids to decrease, making them too acidic. Normally, the body is able to balance the ions that control acidity. This balance is measured on a pH scale from 0 to 14. Acidosis occurs when the pH of the blood falls below 7.35 (normal blood pH is between 7.35 and 7.45).Rinku Chaudhary NSG officer AMU ALIGARH https://www.facebook.com/rinkutch/ Respiratory acidosis is typically caused by an underlying disease or condition. This is also called respiratory failure or ventilatory failure. Suctioning https://youtu.be/hMJGkxvXTW0 Normally, the lungs take in oxygen and exhale CO2. Oxygen passes from the lungs into the blood. CO2 passes from the blood into the lungs. However, sometimes the lungs cant remove enough CO2. This may be due to a decrease in respiratory rate or decrease in air movement due to an underlying condition such as: asth

Metabolic Vs Respiratory Acidosis/alkalosis- When To Tell What's Going On First?

Don't miss your chance to win free admissions prep materials! Click here to see a list of raffles . metabolic vs respiratory acidosis/alkalosis- when to tell what's going on first? So I was doing a practice passage from Kaplan and came across this passage discussing metabolic vs respiratory alkalosis/acidosis. I'm having a lot of trouble answering the questions requiring you to figure out how to determine which one occurs first based on the graph that came with the passage. You can eliminate A and C because point C is in an alkalotic state (is that even a word? Lol.) Point A is physiological pH, PCO2 and PHCO3. Look at the PCO2 levels at point C. This patient is in a state of hyperoxemia (too little CO2 in the body or too much O2 [aka hyperventilation]). The [HCO3-] is also at a basal rate, meaning this isn't a metabolic disorder, eliminating B. I am not sure whether I am looking at it right, but just using my own logic. Eliminate B, because in metabolic alkalosis the initial change is an increase in bicarb , and on the graph it clearly decreases. And it's D because from A to C, you have a decrease in CO2 which is an initial change plus you have a decrease in bicarb because it's a Continue reading >>

    Normal values:
    PH = 7.35 - 7.45
    C02 = 35 - 45
    HC03 = 21-26
    Respiratory acidosis = low ph and high C02
    hypoventilation (eg: COPD, narcs or sedatives, atelectasis)
    *Compensated by metabolic alkalosis (increased HC03)
    For example:
    ph 7.20 C02 60 HC03 24 (uncompensated respiratory acidosis)
    ph 7.33 C02 55 HC03 29 (partially compensated respiratory acidosis)
    ph 7.37 C02 60 HC03 37 (compensated respiratory acidosis)
    Respiratory alkalosis : high ph and low C02
    hyperventilation (eg: anxiety, PE, pain, sepsis, brain injury)
    *Compensated by metabolic acidosis (decreased HC03)
    examples:
    ph 7.51 C02 26 HC03 25 (uncompensated respiratory alkalosis)
    ph 7.47 C02 32 HC03 20 (partially compensated respiratory alkalosis)
    ph 7.43 C02 30 HC03 19 (compensated respiratory alkalosis)
    Metabolic acidosis : low ph and low HC03
    diabetic ketoacidosis, starvation, severe diarrhea
    *Compensated by respiratory alkalosis (decreased C02)
    examples:
    ph 7.23 C02 36 HC03 14 (uncompensated metabolic acidosis)
    ph 7.31 C02 30 HC03 17 (partially compensated metabolic acidosis)
    ph 7.38 C02 26 HC03 20 (compensated metabolic acidosis)
    Metabloic alkalosis = high ph and high HC03
    severe vomiting, potassium deficit, diuretics
    *Compensated by respiratory acidosis (increased C02)
    example:
    ph 7.54 C02 44 HC03 29 (uncompensated metabolic alkalosis)
    ph 7.50 C02 49 HC03 32 (partially compensated metabolic alkalosis)
    ph 7.44 C02 52 HC02 35 (compensated metabolic alkalosis)
    *Remember that compensation corrects the ph.
    Now a simple way to remember this......
    CO2 = acid, makes things acidic
    HCO3 = base, makes things alkalotic
    Remember ROME
    R-Respiratory
    O-Opposite
    M-Metabolic
    E-Equal
    Ok always look at the pH first...
    pH<7.35 = acidosis
    pH>7.45 = alkalosis
    Then, if the CO2 is high or low, then it is respiratory...If the HCO3 is high or low then it is metabolic. How you remember that is that the respiratory system is involved with CO2 (blowing air off or slowing RR), and the kidneys (metabolic) are involved with HCO3 (excreting or not excreting).
    Here is how you think thru it: pH = 7.25 CO2 = 40 HCO3 = 17
    Ok, first, the pH is low so think acidosis. CO2 is WNL. HCO3 is low. Draw arrows if it helps. The abnormal values are both low (think Equal). Metabolic imbalances are equal. So, this must be metabolic acidosis!
    Now, for compensation...If you have a metabolic imbalance, the respiratory system is going to try to compensate. Respiratory = CO2. If the CO2 is normal in the ABG, then there is no compensation going on. Compensation in acidosis will decrease the CO2 because you want to get rid of the acid (CO2). In alkalosis, it will increase because you want to add more acid (CO2)
    If you have a respiratory imbalance, the kidneys will try to compensate. Kidneys = HCO3. If the HCO3 is normal in the ABG, then there is no compensation going on. Compensation in acidosis will increase HCO3 because you want to hold on to the base to make it more alkalotic. In alkalosis, it will decrease because you want to excrete the base to make it more acidic.

Acid-base Disorders - Endocrine And Metabolic Disorders - Merck Manuals Professional Edition

(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 Acid-base disorders are pathologic changes in carbon dioxide partial pressure (Pco2) or serum bicarbonate (HCO3) that typically produce abnormal arterial pH values. Acidosis refers to physiologic processes that cause acid accumulation or alkali loss. Alkalosis refers to physiologic processes that cause alkali accumulation or acid loss. Actual changes in pH depend on the degree of physiologic compensation and whether multiple processes are present. Primary acid-base disturbances are defined as metabolic or respiratory based on clinical context and whether the primary change in pH is due to an alteration in serum HCO3 or in Pco2. Metabolic acidosis is serum HCO3< 24 mEq/L. Causes are Metabolic alkalosis is serum HCO3> 24 mEq/L. Causes are Respiratory acidosis is Pco2> 40 mm Hg (hypercapnia). Cause is Decrease in minute ventilation (hypoventilation) Respiratory alkalosis is Pco2< 40 mm Hg (hypocapnia). Cause is Increase in minute ventilation (hyperventilation) Compensatory mechanisms begin to correct t Continue reading >>
