There are many different ways to remember how to analyze arterial blood gas. Metabolic Equal - In metabolic disorders, the PH and CO2 arrows will move in the same direction. R espiratory O pposite - In respiratory disorders, the pH and CO2 arrows move in opposite directions. This will enable the medical team to treat the patient adequately. In combination with the HCO3, the nurse will be able to fully comprehend the blood gas.īelow is a chart that contains the different values and determines if the cause is respiratory or metabolic-driven, and if, to what degree, the patient is compensating for the pH. This will determine if the changes in the blood gas are due to the respiratory system or metabolically driven. And even with a normal pH level, acidosis or alkalosis may still be present, as the body can compensate to balance the pH. Remember, the lower the pH number, the higher the acid level in the body. If the pH < 7.35, then the patient is acidosis. If a patient’s pH > 7.45, the patient is in alkalosis. The first value a nurse should look at is the pH to determine if the patient is in the normal range, above, or below.

Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg.

Partial pressure of oxygen (PaO2): 75 to 100 mmHg.

According to the National Institute of Health, typical normal values are: The aforementioned components all have different normal values and represent different aspects of the blood gas.

Hemoglobin - This measures the amount of hemoglobin in your blood.

Oxygen content (O2CT) - This measures the amount of oxygen in your blood.

Oxygen saturation (O2 Sat) - This measures how much hemoglobin in your blood is carrying oxygen.

Bicarbonate (HCO3) - This is calculated using the measured values of pH and PaCO2 to determine the amount of the basic compound made from carbon dioxide (CO2.).

Partial pressure of carbon dioxide (PaCO2) - This measures the amount of carbon dioxide in your blood and how well carbon dioxide can move out of your body.

Partial pressure of oxygen (PaO2) - This measures the pressure of oxygen dissolved in your blood.

pH - This measures the balance of acids and bases in your blood.

Some hospitals allow specially trained nurses or phlebotomists to perform this skill but only after an intense training program. The main issue is if the patient does not have a functioning arterial line, a frontline clinician has to draw the arterial sample. While arterial samples are the best for diagnostic reasons, they do provide some challenges for nurses and providers. Most ICUs have one on the unit for a quick turnaround. Once the blood is obtained, it is either sent to the hospital’s central lab for analysis or tested by the respiratory therapist on the unit’s blood gas analyzer. If the patient already has a pre-existing arterial line, this can be used to obtain the sample. However, the femoral artery and brachial artery can be used if necessary.

The radial artery on the wrist is most commonly used to obtain the sample. Blood can be drawn via an arterial stick from the wrist, groin, or above the elbow.
