What is the normal range of pH and PCO2?
Were the pH and PCO2 in the normal range? You correctly answered: c. Both pH and PCO2 were in the normal range.
What causes high PCO2 levels?
The most common cause of increased PCO2 is an absolute decrease in ventilation. Increased CO2 production without increased ventilation, such as a patient with sepsis, can also cause respiratory acidosis. Patients who have increased physiological dead space (eg, emphysema) will have decreased effective ventilation.
What is a high PCO2 level?
The pCO2 gives an indication of the respiratory component of the blood gas results. A high and low value indicates hypercapnea (hypoventilation) and hypocapnea (hyperventilation), respectively. A high pCO2 is compatible with a respiratory acidosis and a low pCO2 with a respiratory alkalosis.
What is pac02 normal range?
Normal Results Partial pressure of oxygen (PaO2): 75 to 100 millimeters of mercury (mm Hg), or 10.5 to 13.5 kilopascal (kPa) Partial pressure of carbon dioxide (PaCO2): 38 to 42 mm Hg (5.1 to 5.6 kPa)
How is high PCO2 treated?
- Ventilation. There are two types of ventilation used for hypercapnia:
- Medication. Certain medications can assist breathing, such as:
- Oxygen therapy. People who undergo oxygen therapy regularly use a device to deliver oxygen to the lungs.
- Lifestyle changes.
How does the respiratory system compensate for metabolic acidosis?
Respiratory compensation for metabolic acidosis increases the respiratory rate to drive off CO2 and readjust the bicarbonate to carbonic acid ratio to the 20:1 level. This adjustment can occur within minutes. Respiratory compensation for metabolic alkalosis is not as adept as its compensation for acidosis.
How do kidneys respond to metabolic acidosis?
The renal response to metabolic acidosis is mediated, in part, by increased expression of the genes encoding key enzymes of glutamine catabolism and various ion transporters that contribute to the increased synthesis and excretion of ammonium ions and the net production and release of bicarbonate ions.
