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.

What is respiratory alkalosis and acidosis?
Normally, the respiratory system keeps these two gases in balance. Respiratory alkalosis occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the blood becomes too acidic, respiratory acidosis occurs.
What is the main difference between acidosis and alkalosis?
Acidosis is a condition in which there is too much acid in the body fluids. It is the opposite of alkalosis (a condition in which there is too much base in the body fluids).
What is respiratory alkalosis?
Respiratory alkalosis is a condition marked by a low level of carbon dioxide in the blood due to breathing excessively.
What is respiratory acidosis?
Respiratory acidosis is a condition that occurs when the lungs cannot remove all of the carbon dioxide the body produces. This causes body fluids, especially the blood, to become too acidic.
How can you tell the difference between metabolic and respiratory acidosis?
The main difference between metabolic and respiratory acidosis is that the metabolic acidosis occurs due to the production of organic acids such as lactic acid and ketone bodies whereas the respiratory acidosis occurs when lungs have failed to remove excess carbon dioxide from the blood.
How can you distinguish between metabolic acidosis and respiratory acidosis?
The pCO2 determines whether an acidosis is respiratory or metabolic in origin. For a respiratory acidosis, the pCO2 is greater than 40 to 45 due to decreased ventilation. Metabolic acidosis is due to alterations in bicarbonate, so the pCO2 is less than 40 since it is not the cause of the primary acid-base disturbance.
Does respiratory alkalosis cause metabolic acidosis?
Exhalation of large amounts of CO2 causes respiratory alkalosis in arterial blood (hence on ABG measurements), but poor systemic perfusion and cellular ischemia cause cellular acidosis, leading to acidosis of venous blood.
How do you remember the difference between acidosis and alkalosis?
When you have those lab values memorized, it’s easy to recognize what is abnormal. Now, if a patient’s pH falls below 7.35, they are in a state of acidosis (remember the acidic-lemon?). If the patient’s pH is above 7.45, the patient would be in a state of alkalosis (the elk-loser).
What are the causes of respiratory alkalosis?
Respiratory alkalosis is usually caused by over-breathing (called hyperventilation) that occurs when you breathe very deeply or rapidly. Causes of hyperventilation include:
- Anxiety or panic.
- Fever.
- Pregnancy (this is normal).
- Pain.
- Tumor.
- Trauma.
- Severe anemia.
- Liver disease.
Is pneumonia respiratory acidosis or alkalosis?
Respiratory alkalosis is commonly found in patients with asthma, pneumonia & pulmonary embolism.
Is COPD respiratory acidosis or alkalosis?
Chronic obstructive pulmonary disease (COPD) is a common group of diseases that are particularly likely to cause respiratory acidosis. In this article, we look at the symptoms, causes, and treatment options for respiratory acidosis.
What happens respiratory acidosis?
Respiratory acidosis is a serious medical condition that occurs when the lungs can’t remove all of the carbon dioxide produced by the body through normal metabolism. The blood becomes acidified, leading to increasingly serious symptoms, from sleepiness to coma.
What are two causes of respiratory acidosis?
Respiratory acidosis involves a decrease in respiratory rate and/or volume (hypoventilation). Common causes include impaired respiratory drive (eg, due to toxins, CNS disease), and airflow obstruction (eg, due to asthma, COPD [chronic obstructive pulmonary disease], sleep apnea, airway edema).
What is the main cause of respiratory acidosis?
Respiratory acidosis typically occurs due to failure of ventilation and accumulation of carbon dioxide. The primary disturbance is an elevated arterial partial pressure of carbon dioxide (pCO2) and a decreased ratio of arterial bicarbonate to arterial pCO2, which results in a decrease in the pH of the blood.
How does the respiratory system compensate for respiratory acidosis?
The kidneys compensate for a respiratory acidosis by tubular cells reabsorbing more HCO3 from the tubular fluid, collecting duct cells secreting more H+ and generating more HCO3, and ammoniagenesis leading to increased formation of the NH3 buffer.
