What does the Davenport diagram show?
Davenport diagrams are graphic displays of acid-base states. They illustrate the dynamic relationships between arterial blood pH, bicarbonate and non-bicarbonate buffers, and the partial pressure of carbon dioxide.
What is the blood buffer line?
Point C represents the relationships when carbonic acid is removed from blood (e.g., by decreasing arterial carbon dioxide tension). The line connecting Points A, B, and C defines the buffer line for arterial blood.
What is acid-base disorders?
Acid-base disorders are pathologic changes in carbon dioxide partial pressure (Pco 2) or serum bicarbonate (HCO 3 −) that typically produce abnormal arterial pH values. Acidemia is serum pH < 7.35. Alkalemia is serum pH > 7.45. Acidosis refers to physiologic processes that cause acid accumulation or alkali loss.
What causes 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.
What is alkalosis and acidosis?
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 are the 4 common mixed acid base disorders?
Disorders of Acid–Base Balance. Disorders of acid–base balance are classified according to their cause, and the direction of the pH change, into respiratory acidosis, metabolic acidosis, respiratory alkalosis, or metabolic alkalosis.
What lab test is done for acid base disorder?
To detect an acid-base disturbance, both a blood gas analysis and chemistry panel should be performed. This combines traditional blood gas analysis (Henderson-Hasselback equation) and the strong ion approach (by evaluating the contributions of electrolytes, in particular).
What does too much co2 in the blood cause?
Having too much carbon dioxide in the body can cause symptoms like headache, fatigue, and muscle twitches—such common ailments that you can see why many people dismiss the symptoms as simply pesky. Most of the time, they are.
