Can you have respiratory and metabolic acidosis?

It is possible for a person to have more than one acid-base disorder at the same time. Examples include ingestion of aspirin (which can produce both a respiratory alkalosis and metabolic acidosis) and those with lung disease who are taking diuretics (respiratory acidosis plus metabolic alkalosis).

Can you have both respiratory and metabolic acidosis?

For combined respiratory and metabolic acidosis, the PaCO2 level is elevated and the HCO3 level is decreased. Too much acid and too little base in the blood causes an acidotic pH level, and the result is combined respiratory and metabolic acidosis.

What can cause respiratory and metabolic acidosis?

Common causes of respiratory acidosis

  • asthma.
  • chronic obstructive pulmonary disease (COPD)
  • acute pulmonary edema.
  • severe obesity (which can interfere with expansion of the lungs)
  • neuromuscular disorders (such as multiple sclerosis or muscular dystrophy)
  • scoliosis.

How does the respiratory system respond to metabolic acidosis?

Respiratory compensation (alkalosis): A primary metabolic acidosis stimulates peripheral chemoreceptors (which respond to low pH or high H+), causing hyperventilation and a decrease in pCO2 or a secondary respiratory alkalosis.

Can metabolic acidosis cause respiratory alkalosis?

Respiratory alkalosis is a pathology that is secondary to hyperventilation. Hyperventilation typically occurs in response to an insult such as hypoxia, metabolic acidosis, pain, anxiety, or increased metabolic demand. Respiratory alkalosis in itself is not life-threatening; however, the underlying etiology may be.

How do I know if I have respiratory or metabolic compensation?

Assume metabolic cause when respiratory is ruled out.

If PaCO2 is abnormal and pH is normal, it indicates compensation. pH > 7.4 would be a compensated alkalosis. pH < 7.4 would be a compensated acidosis.

How do you know if its metabolic acidosis or respiratory acidosis?

Metabolic acidosis: patients who are acidotic and have a HCO3– <22 (base excess <–2); Respiratory acidosis: patients who are acidotic with a PaCO2 >6; Metabolic alkalosis: patients who are alkalotic with a HCO3– >28 (base excess >+2); Respiratory alkalosis: patients who are alkalotic with a PaCO2 <4.7.

Which condition is likely to cause metabolic acidosis?

The most common causes of hyperchloremic metabolic acidosis are gastrointestinal bicarbonate loss, renal tubular acidosis, drugs-induced hyperkalemia, early renal failure and administration of acids.

How do you fix metabolic acidosis?

Treatment for metabolic acidosis works in three main ways: excreting or getting rid of excess acids. buffering acids with a base to balance blood acidity. preventing the body from making too many acids.

Diabetes treatment

  1. insulin.
  2. diabetes medications.
  3. fluids.
  4. electrolytes (sodium, chloride, potassium)

How do you fix respiratory acidosis?


  1. Bronchodilator medicines and corticosteroids to reverse some types of airway obstruction.
  2. Noninvasive positive-pressure ventilation (sometimes called CPAP or BiPAP) or a breathing machine, if needed.
  3. Oxygen if the blood oxygen level is low.
  4. Treatment to stop smoking.


How long does the respiratory system take to respond to metabolic acidosis?

Metabolic Acidosis

Respiratory compensation for metabolic disorders is quite fast (within minutes) and reaches maximal values within 24 hours. A decrease in Pco2 of 1 to 1.5 mm Hg should be observed for each mEq/L decrease of in metabolic acidosis.

How would the respiratory system compensate for metabolic acidosis quizlet?

The respiratory system compensates for metabolic acidosis by expelling CO2 at a faster rate (breathing rate increase).

What is the difference between metabolic acidosis and respiratory alkalosis?

Acidosis refers to an excess of acid in the blood that causes the pH to fall below 7.35, and alkalosis refers to an excess of base in the blood that causes the pH to rise above 7.45. Many conditions and diseases can interfere with pH control in the body and cause a person’s blood pH to fall outside of healthy limits.

What are the symptoms of metabolic alkalosis?

Symptoms of alkalosis can include any of the following:

  • Confusion (can progress to stupor or coma)
  • Hand tremor.
  • Lightheadedness.
  • Muscle twitching.
  • Nausea, vomiting.
  • Numbness or tingling in the face, hands, or feet.
  • Prolonged muscle spasms (tetany)


What is the difference between metabolic acidosis and alkalosis?

Acidosis is when your blood pH drops below 7.35 and becomes too acidic. Alkalosis is when your blood pH is higher than 7.45 and becomes too alkaline.
