What does high PO2 mean?
PO2 (partial pressure of oxygen) reflects the amount of oxygen gas dissolved in the blood. It primarily measures the effectiveness of the lungs in pulling oxygen into the blood stream from the atmosphere. Elevated pO2 levels are associated with: Increased oxygen levels in the inhaled air.
What does the HCO3 value represent?
This test measures the amount of bicarbonate, a form of carbon dioxide, in your blood. Bicarbonate, also known as HCO3, is a byproduct of your body’s metabolism.
What does HCO3 mean in ABG?
bicarbonate
ABG Components: pH = measured acid-base balance of the blood. PaO2 = measured the partial pressure of oxygen in arterial blood. PaCO2 = measured the partial pressure of carbon dioxide in arterial blood. HCO3 = calculated concentration of bicarbonate in arterial blood.
What is a normal pc02 level?
Generally, under normal physiologic conditions, the value of PCO2 ranges between 35 to 45 mmHg, or 4.7 to 6.0 kPa.
What should your pO2 level be?
The PaO2 measurement shows the oxygen pressure in the blood. Most healthy adults have a PaO2 within the normal range of 80–100 mmHg. If a PaO2 level is lower than 80 mmHg, it means that a person is not getting enough oxygen .
What is normal p02?
The normally accepted range for pO2 is 10-13kPa (Muir et al, 2002), but the exact value will depend upon age and history. For example a 20 year old may have a normal pO2 of 12.5-13.0kPa while a 65 year old may have a normal pO2 of 10.8kPa (Resuscitation Council UK, 2001).
What does a low HCO3 level mean?
Low bicarbonate levels in the blood are a sign of metabolic acidosis. It is an alkali (also known as base), the opposite of acid, and can balance acid. It keeps our blood from becoming too acidic. Healthy kidneys help keep your bicarbonate levels in balance.
What happens when HCO3 is low?
What does low HCO3 mean?
Bicarbonate belongs to a group of electrolytes, which help keep your body hydrated and make sure your blood has the right amount of acidity. Too much or too little bicarbonate can be a sign of a number of conditions, including diarrhea, liver failure, kidney disease, and anorexia.
How does HCO3 affect pH?
HCO3- level denotes metabolic/kidney effect. An elevated HCO3- is raising the pH and vice versa. If the pH is acidotic, look for the number that corresponds with a lower pH. If it is a respiratory acidosis, the CO2 should be high.
