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

Quantitative Acid-base Dynamics In Chronic Pulmonary Disease: Defense Of Ph During Acute Respiratory Acidosis Superimposed Upon Chronic Hypercapnia

The defense of the extracellular pH was evaluated in 17 patients with chronic obstructive lung disease and chronic hypercapnia during superimposed acute respiratory acidosis. In group I the chronic stable state PaCO2-pH-HCO3 was not defined; in groups IA and II the stable state was defined. Duration of acute acidosis in groups I and IA was 16 and 23 hr, respectively; in group II, 30 min. The defense of pH in groups I and IA was greater than acute hypercapnia in normal man but less than chronic stable hypercapnia (P < 0.05). The pH in group II approached that of normal man during acute respiratory acidosis. Plasma bicarbonate concentrations paralleled the ( H+ ) responses. A wide confidence band based on these observations overlapped the previously established bands for acute and chronic hypercapnia. In the clinical situation, variable PaCO2 exposures create variable in vivo carbon dioxide titration curves. Thus, the defense of the extracellular pH during acute respiratory acidosis superimposed upon chronic hypercapnia is related temporally to renal buffering mechanisms. Under these circumstances, prediction bands for steady state acute or stable chronic hypercapnia are not valid f Continue reading >>

    Hi guys! Could someone answer how does acetoacetate change the pH? I mean, if it is released in ionized form (COO-) how can it change the pH of blood? I cant understand, where does it get protonized? Sorry for my English

  2. Dr. Stalker

    Ketone bodies can contribute to blood pH changes. Specifically, they acidify the blood by donating protons. In organic chemistry/biochemistry you'll learn that a substance doesn't necessarily need to have a -COOH to have acidic properties. It just so happens the hydrogen in the -COOH is very acidic and there's many reasons why. Without diving into all of those, the H in -OH can sometimes be acidic.
    To answer your question specifically about ketones, look at the carboxyl group. If we look at the carbons attached to the carbon that is double bonded to the oxygen, we have an opportunity for resonance. If we deprotonate the carbon adjacent to the carbon in the ketone functional group, those electrons can form a double bond to the carbon and push the one of the double bonds onto the oxygen leading to resonance stability.
    I unfortunately couldn't find a better image than this one (ignore the fact that this has two ketone functional groups)

  3. AlexBest96

    Dr. Stalker, so ketones are not protonized in mitochondria and get in blood in COOH form? they change the pH in ionized form by the mechanism, which you explain?

Case 5 Answers - Arterial Blood Gas - Clinical Respiratory Diseases & Critical Care Medicine, Seattle - Med 610 - University Of Washington School Of Medicine

A 68 year-old man with a history of very severe COPD (FEV1 ~ 1.0L, <25% predicted) and chronic carbon dioxide retention (Baseline PCO2 58) presents to the emergency room complaining of worsening dyspnea and an increase in the frequency and purulence of his sputum production over the past 2 days. His oxygen saturation is 78% on room air. Before he is place on supplemental oxygen, a room air arterial blood gas is drawn and reveals: pH 7.25, PCO2 68, PO2 48, HCO3- 31 The patient has a high PCO2 (respiratory acidosis) and a high bicarbonate (metabolic alkalosis). The combination of the low pH and the high PCO2 tells us that the respiratory acidosis is the primary process. The metabolic alkalosis is the compensatory process. The pH is still low despite this metabolic compensation Summary: Primary respiratory acidosis with compensatory metabolic alkalosis. The alveolar-arterial oxygen difference is 17 mmHg. This value is elevated, suggesting that the hypoxemia is due to either shunt or areas of low V/Q (the more likely explanation in a patient with COPD) and cannot be explained by hypoventilation alone. The patient has very severe COPD and chronic carbon dioxide retention. As a result, Continue reading >>

    Hi all. What a great forum! Such nice helpful people. Thank you, Seth and everbody involved.
    I started doing canola oil on Monday and have noticed a great change in appetite almost immediately (didn't even want to finish a slice of pizza, which for me is quite remarkable).
    My question is, has anyone else gotten a tingly feeling in the tongue? The closest I can describe it is the way I used to feel back in the early 80's when I experimented with snorting coke. But it's a very mild tingling. I wonder if it has to do with the speeding up of my metabolism.
    Any thoughts?

    My lips went numb, today! Odd. But only once! And may be totally unrelated.

  3. tarheelatheart

    You guys may be describing sensations of the cranial nerves. The tongue (hypoglossal) would be reacting to the oil maybe? And numb lip (if that is related) could be a brief facial nerve reaction. This is just speculation. After I take the oil, I get a sensation in my head that is more brief now than at first, but it's right in the cavernous sinus and It feels like it's in the cranial nerve area. Odd, isn't it?

Irocket Learning Module: Intro To Arterial Blood Gases, Pt. 1

Acute vs. Chronic Respiratory Disturbances Remember respiratory processes alter the blood pH by changing the carbon dioxide levels. When CO2 accumulates in the blood (elevated PaCO2), as when a person hypoventilates, acid builds up and the pH decreases. This is called respiratory acidosis. Similarly, with increased CO2 elimination (low PaCO2), as when a person hyperventilates, the amount of acid in the blood decreases and the pH increases. This is called respiratory alkalosis. Primary respiratory disturbances can be acute or chronic. Near drowning, asthma attack, respiratory arrest, drug overdose, upper airway obstruction, panic attack Emphysema, chronic bronchitis, high altitude travel, neuromuscular disease When anaylzing an ABG of a person with a primary respiratory disturbance, it is important to determine if the problem is acute or chronic. For example, acute respiratory acidosis is associated with an abrupt and sometimes significant decline in pH; it is a sign of possible acute respiratory failure that requires urgent intervention. However, chronic respiratory failure occurs over weeks to months to years. The acidosis associated with it is mild because the kidney has had tim Continue reading >>

    Does acute DKA cause hyperkalemia, or is the potassium normal or low due to osmotic diuresis? I get the acute affect of metabolic acidosis on potassium (K+ shifts from intracellular to extracellular compartments). According to MedEssentials, the initial response (<24 hours) is increased serum potassium. The chronic effect occuring within 24 hours is a compensatory increase in Aldosterone that normalizes or ultimatley decreases the serum K+. Then it says on another page that because of osmotic diuresis, there is K+ wasting with DKA. On top of that, I had a question about a diabetic patient in DKA with signs of hyperkalemia. Needless to say, I'm a bit confused. Any help is appreciated.

  2. FutureDoc4

    I remember this being a tricky point:
    1) DKA leads to a decreased TOTAL body K+ (due to diuresis) (increase urine flow, increase K+ loss)
    2) Like you said, during DKA, acidosis causes an exchange of H+/K+ leading to hyperkalemia.
    So, TOTAL body K+ is low, but the patient presents with hyperkalemia. Why is this important? Give, insulin, pushes the K+ back into the cells and can quickly precipitate hypokalemia and (which we all know is bad). Hope that is helpful.

  3. Cooolguy

    DKA-->Anion gap M. Acidosis-->K+ shift to extracellular component--> hyperkalemia-->symptoms and signs
    DKA--> increased osmoles-->Osmotic diuresis-->loss of K+ in urine-->decreased total body K+ (because more has been seeped from the cells)
    --dont confuse total body K+ with EC K+
    Note: osmotic diuresis also causes polyuria, ketonuria, glycosuria, and loss of Na+ in urine--> Hyponatremia
    DKA tx: Insulin (helps put K+ back into cells), and K+ (to replenish the low total potassium
    Hope it helps
