Recent studies have demonstrated that there is a direct correlation between peripheral venous and arterial blood gas measures and that peripheral venous CO2 measures may be used as alternatives to arterial CO2 measure.The purpose of this study is to evaluate brainstem response during the apnea challenge test to a rise in venous CO2 and correlate it with the rise in arterial measured CO2.

Blood gases are a group of tests that are performed together to measure the pH and the amount of oxygen (O 2) and carbon dioxide (CO 2) present in a sample of blood, usually from an artery, in order to evaluate lung function and help detect an acid-base imbalance that could indicate a respiratory, metabolic or kidney disorder.

Venous blood gas measurements are widely used instead of arterial blood gas measurements and evidence from case studies suggests there is sufficient agreement between them, when combined with other clinical findings, to use a venous blood gas to guide initial treatment. 2019-05-23 · The CO2 test is a simple blood test that measures the amount of CO2 gas in a person’s blood. It is usually part of a larger test called an electrolyte panel. To determine the agreement between arterial and venous samples in a pathologically diverse patient population presenting at an emergency department (ED) with Because oxygen completely saturates hemoglobin after only a fraction of the time that blood is in contact with alveolar gas, hypoxemia due to impaired diffusing capacity occurs only when cardiac output is increased (eg, during exercise), when barometric pressure is low (eg, at high altitudes), or when > 50% of the pulmonary parenchyma is destroyed.

PVD - arteriole vs venous.

Venous blood is the specimen of choice for most routine laboratory tests. The blood is obtained by direct puncture to a vein, most often located in the antecubital area of the arm or the back (top) of the hand. At times, venous blood may be obtained using a vascular access device (VAD) such as a central venous pressure line or Hickmann Catheter

VBGs are popular as it is far less painful for the patient to obtain a venous sample compared to an arterial sample. In addition, obtaining ABGs carries well known risks.
