Venous blood gases do not evaluate arterial oxygenation, therefore, they must be combined with pulse oximetry values to fully assess ventilation. The role of venous blood gas samples in the evaluation of oxygen delivery is discussed below.
30 Mar 2014 If patient's O2 saturation <90%; pH, pCO2, HCO3 and also pO2 values in venous blood gas sample can be used instead of arterial blood gas
In venous blood sampling, a needle is inserted into a vein to collect a sample of blood for testing. Peripheral veins, typically the antecubital veins, are the usual sites for venous blood sampling. Ultrasound guidance , when equipment and trained personnel are available, can facilitate blood sampling from deep, nonpalpable veins. Arterial Blood Gas (ABG) and mixed or central venous blood gas (VBG) are mainstays of diagnosis and dictate therapy in acute, severe illness. The focus of th According to the Center for Disease Control (CDC) there are approximately 75 million American adults (32%) who have high blood pressure. However, only half of those actually have the condition under control.
Methods Venous blood gases do not evaluate arterial oxygenation, therefore, they must be combined with pulse oximetry values to fully assess ventilation. The role of venous blood gas samples in the evaluation of oxygen delivery is discussed below. How to convert venous blood gas values to arterial values Arterial blood gas is the gold standard for blood gas and acid-based testing in critical care. There is a trend towards the use of venous blood, as venous punctures are less invasive for the patient and less complex for healthcare providers..

2 Gennis and Arterial and venous blood gases (ABGs and VBGs, respectively) are routinely done in acute care settings to ascertain acid-base status, gas exchange, oxygen consumption, and electrolyte levels. In the OR and ICU settings, most of my patients have arterial lines from which ABGs can be drawn and interpreted . The values in arterial blood are relatively constant and clinically significant because they reflect lung function. Blood gas measurements of venous blood are not as useful because these values are far more variable.
The median blood loss in this group was 2.5 l (range 1.5–7 l) with atony the most An audit of epidurals and venous thromboembolism prescriptions and the carbon footprint the NHS (of which anaesthetic gases form 5%).
Most commonly, blood may be collected from one of the following arteries: Radial artery in the wrist; Femoral artery in the groin; Brachial artery in the arm Arterial blood gases (ABGs), venous blood gases, capillary blood gases, cord blood gases. Rationale To assess oxygenation and acid-base balance.

Venous blood gas samples are adequate for the clinical assessment of acid-base disorders in patients that are hemodynamically stable. 15,45 Peripheral venous PO 2 values are not representative of arterial oxygen values; however, the blood from veins in the tongue or the claw may be “arterialized” under certain conditions and used for this purpose. 15,46-48 A venous PO 2 of less than 30 mm
Arterial and venous pH results, arterial and venous bicarbonate measurements and arterial bicarbonate and The aforementioned components all have different normal values and represent different aspects of the blood gas. According to the National Institute of Health, typical normal values are: pH: 7.35-7.45; Partial pressure of oxygen (PaO2): 75 to 100 mmHg; Partial pressure of carbon dioxide (PaCO2): 35-45 mmHg; Bicarbonate (HCO3): 22-26 mEq/L The mean difference between arterial and venous pH values was 0.03 (range 0.0 to 0.11).

Venous Blood Gas (VBG) sampling is an appealing option to resource limited services. VBG samples can be performed in any clinical setting and staff require training in venipuncture only. Although normal ranges for ABG measurements and their clinical relevance are well established and understood by clinicians, the same cannot be claimed for VBG measurement.
