Difference between ABG and VBG
ABG Vs VBG:
For an individual to be recruited for emergency services, that person is required to be highly trained in the medical profession. They must be ready to provide their services which includes providing medical assistance and also administering medicine during emergency situations. In order to draw a conclusion over the condition of a patient, a medical professional is required to check many aspects of that particular individual such as the patient’s airway, breathing, circulation, etc. the terms AVG and VBG are two such components that are thus examined in a patient prior to prescribing medicine or providing treatment to the patient.
What is ABG?
ABG stands for Arterial Blood Gas which signifies the arterial oxygen tension (PaO2), carbon dioxide tension (PaCO2), acidity (pH) and arterial oxyhemoglobin saturation (SaO2) and is usually performed through a blood test using the blood from an artery. Usually the radial artery at the wrist or the femoral artery in the groin is punctured with a needle from which a small amount of blood is drawn to be tested. It is one of the most common tests performed for patients in intensive care and the information obtained through ABG can prove to be vital when treating patients with critical illness or respiratory disease.
What is VBG?
VBG stands for Venous blood gas which is useful for evaluating oxygen and carbon dioxide gas exchange, respiratory function which includes hypoxia, acid/base balance which is often used in the assessment of asthma, cases of chronic obstructive pulmonary disease and also, other types of lung disease as well as embolism which includes fat embolism and coronary artery disease.
Venous blood is deoxygenated blood in the circulatory system which runs in veins from the organs to the heart. It is obtained from a venipuncture or by way of a simple fingerprick.
What is the difference between VBG and ABG?
While both ABG and VBG can be crucial in saving lives and treating patients, they are different things. ABG stands for Arterial Blood Gas and the blood for this test is obtained from an artery whereas the blood for a VBG is obtained from a vein. Also, ABG is performed in order to test the arterial oxygen tension (PaO2), carbon dioxide tension (PaCO2), acidity (pH) and arterial oxyhemoglobin saturation (SaO2) which is then utilized in treating patients with critical illness or respiratory disease whereas VBG is performed in order to evaluate oxygen and carbon dioxide gas exchange, respiratory functions which include hypoxia, acid balance, base balance which is often used in the assessment of asthma, cases of chronic obstructive pulmonary disease and also, other types of lung disease as well as embolism which includes fat embolism and coronary artery disease.
Also, venous blood is known to be much warmer than the arterial blood and possesses lower amounts of oxygen and also a lower PH level. It also contains a high amount of glucose and urea and other wate products than in arterial blood and the difference between arterial blood and venous blood is referred to as the arteriovenous oxygen difference.
