Here you can get information about How to Interpret Blood Gas Results. Your doctor may run a blood gas analysis or arterial blood gas (ABG) test if you’re showing the signs of an oxygen, CO2, or pH imbalance like confusion or difficulty breathing.
This test measures the partial levels of those substances using a small blood sample. From these numbers, your doctor can find out how well your lungs move oxygen into your blood and take away CO2 from your body. It also can indicate certain medical conditions like kidney or heart failure, drug overdose, or uncontrolled diabetes. Your doctor is the best person to interpret the test results, but you’ll also get a thought about them yourself. You’ll interpret your test results by reviewing them closely and considering other data.
Reviewing Your Test Results Closely
- Evaluate the results together with your doctor. The simplest way to interpret your blood results is by lecture your doctor. They understand the information and results better than anyone. Making an assessment on your own can cause misdiagnosis or complications from self-treatment. Ask your doctor any questions you’ll have about individual or total levels and what they’ll indicate.
- Have your doctor undergo each series of numbers individually, explaining what they test for and what your specific results may mean.
- Ask your doctor to match previous results with the new ones to raised judge where you’re physically.
- Check out the pH number. This measures the number of hydrogen ions in your blood, which can indicate conditions like COPD, asthma, pregnancy, diabetic ketoacidosis (DKA), lung disease, disease, or drug use. The normal range for pH values is between 7.35 to 7.45.
- If the pH level is below 7.38, then you’ll have more acidic blood from conditions like airway obstruction, COPD, asthma, sleep disordered breathing, or neuromuscular impairment.
- If the pH level is above 7.45, you’ll have an alkalosis, which could indicate stimulation of the central systema nervosum , lung disease, severe anemia, drug use, or pregnancy.
- Check bicarbonate, or HCO3, numbers. Your kidneys produce bicarbonate and help maintain a traditional pH. the normal level for bicarbonate is between 22 and 26 milliEquivalents Per Liter (mEq/L). a disruption of your bicarbonate levels may indicate conditions like respiratory failure, anorexia, and liver failure.
- An HCO3 level is below 24 mEq/L indicates acidosis. It’s going to be the results of conditions including diarrhea, liver failure and kidney disease.
- An HCO3 level above 26 mEq/L indicates alkalosis. This might be the results of dehydration, vomiting, and anorexia.
- Examine the PaCO2 number. Partial pressure of CO2, or PaCO2, measures the CO2 in your blood. The traditional level for PaCO2 is between 38 and 45 mmHg. Disrupted levels may indicate shock, kidney failure, or chronic vomiting.
- Respiratory alkalosis is present if the PaCO2 number is below 35 mmHg. This suggests there’s insufficient CO2 within the blood. It can signal kidney failure, shock, diabetic ketoacidosis, hyperventilation, pain, or anxiety.
- Carbon dioxide acidosis is present if the PaCO2 number is above 45 mmHg. This suggests that there’s an excessive amount of CO2 within the blood. This will be a symbol of chronic vomiting, low blood potassium, COPD, or pneumonia.
- Inspect the PaO2 number. Partial pressure of oxygen, or PaO2, measures how well oxygen can be due to your lungs into your blood. The normal level is between 75 and 100 mmHg. Higher or lower levels may indicate conditions like anemia, carbon monoxide poisoning, or red blood cell disease.
- Notice oxygen saturation. How well your hemoglobin carries oxygen to your red blood cells is named oxygen saturation. The traditional levels are between 94 and 100%. Lower saturation rates may indicate the following:
- Congenital heart defects
- COPD or emphysema
- Strained abdominal muscles
- Collapsed lung
- Pulmonary edema or embolism
Considering Other Data
- Figure in medications or drugs. Certain factors like your health, medication you’re taking, and where you reside can affect the results of your blood gas test. If you’re taking any of the following medications or drugs, recognize that they’ll disrupt your blood gas results:
- Blood thinners, including aspirin
- Illicit drugs
- Tobacco or secondhand smoke
- Tetracycline (antibiotics)
- Recognize your location. The quantity of oxygen within the air decreases with elevation, which may also affect your blood gas results. If you reside at altitudes of three, 000 feet (900 meters) or higher, factor this in your test. Ask your doctor to correlate your partial pressure of oxygen together with your location or factor that a healthy level of saturation is 80-90% between 10,000 – 15,000 feet.
- Respiratory alkalosis is usually related to people getting to mountainous areas. Hyperventilation is particularly likely when ascent is just too rapid and there hasn’t been enough time to acclimate.
- Acknowledge current medical conditions. Medical conditions starting from liver failure to an easy fever can affect your blood gas results. Consider these as you review your test or discuss it together with your doctor. The subsequent conditions may disrupt normal blood gas levels:
- Prior to drug overdose
- Head or neck injury
- Respiratory disorders like asthma and COPD
- Congestive heart failure
- renal failure
- Blood disorders like hemophilia
- Compare earlier tests. If you’ve had previous blood gas tests, review the results from them. This will offer you a thought of any discrepancies which will indicate a replacement condition or improvement of another. Remember to debate these results together with your doctor, too.
- Discuss test results with your doctor to make sure proper interpretation of the results.
