Improving the Validity of Peripheral Venous Blood Gas Analysis as an Estimate of Arterial Blood Gas by Correcting the Venous Values with SvO2

Journal of Emergency Medicine, 2013
, Abstract—Background: Peripheral venous blood gas (pVBG) analysis in replacement of arterial blood gas (ABG) is limited by the unpredictable differences between arterial and venous values, especially for PCO2 and pH (DPCO2 and DpH). Objectives: We hypothesized that, using the theoretical relationship linking SvO2 and blood flow, we could diminish the ...

The use of mixed venous blood gas determinations in traumatic shock

Annals of Emergency Medicine, 1980
A series of 10 seriously injured patients requiring resuscitation and definitive operative control of hemorrhage was studied. Simultaneous arterial and mixed venous blood gases were measured sequentially throughout the resuscitative and operative periods. Improvement of the mixed venous oxygen saturation was associated with survival.

Umbilical venous blood gas analysis for neonatal assessment [PDF]

Journal of Pediatric Intensive Care, 2015
Umbilical venous pH is claimed to mirror fetal acid-base status. Importantly, it is easier to perform. The aim of this study is to : 1. Evaluate the umbilical venous blood gas (UVBG) profile of normal newborns and to compare UVBG in the following situations: presence or absence of asphyxia presence or absence of meconium-stained amniotic fluid presence

Comparison of blood gas values in arterial and venous blood

The Indian Journal of Pediatrics, 2003
To compare pH and PCO2 values of simultaneously obtained arterial, arterialized capillary, and venous blood samples and also to compare oxygen saturation (ASaO2) measured in arterial blood and oxygen saturation by pulse oximetry (PSaO2).Prospective study was done in the children admitted in the Pediatric Intensive Care Unit of Christian Medical College

Reference intervals for venous blood gas measurement in adults

Clinical Chemistry and Laboratory Medicine (CCLM), 2020
Abstract Objectives Venous blood gas (VBG) analysis is becoming a popular alternative to arterial blood gas (ABG) analysis due to reduced risk of complications at phlebotomy and ease of draw. In lack of published data, this study aimed to establish reference intervals (RI) for correct interpretation ...

Prevention of venous blood gas embolism with blood microfilters

Anaesthesia, 1977
The efficacy of blood microfilters in removal of the gaseous emboli produced during the warming of blood for transfusion is demonstrated experimentally. It is suggested that when blood microfilters are used they should be placed distal to any blood warming device.

Effect of syringe underfilling on the quality of venous blood gas analysis

Diagnosis, 2023
Abstract Objectives There is limited information on the influence of collecting small amounts of blood on the quality of blood gas analysis. Therefore, the purpose of this study was to investigate the effects of different degrees of underfilling of syringes on test results of venous blood gas ...

Venous or Arterial Blood Gas Measurement

JAMA: The Journal of the American Medical Association, 1971
To the Editor.— In further reply to the question of McGee regarding the value of venous versus arterial blood as a source of measuring blood gases, I find the answers given do not clearly define what is being measured. If one is interested in acid-base balance, a simultaneous measurement of hemoglobin, pH, and carbon dioxide tension (Pco 2 ) will ...

CORRELATION OF VENOUS BLOOD GAS AND PULSE OXIMETRY WITH ARTERIAL BLOOD GAS IN CRITICALLY ILL PATIENTS

INTERNATIONAL JOURNAL OF SCIENTIFIC RESEARCH, 2021
Introduction: Arterial blood gas (ABG) analysis is the gold standard method and frequently performed intervention to evaluate acid-base status along with adequacy of ventilation and oxygenation among patients with predominantly critical / acute diseases. Aims And Objectives: The aim of this study is to evaluate the correlation of VBG analysis and pulse

Prediction of Arterial Blood Gas from Venous Blood Gas: How Far We’ve Come

Proceedings Book of International Conference and Exhibition on The Indonesian Medical Education Research Institute, 2023
Venous blood gas has been extensively studied as a replacement for arterial blood gas, which remains the gold standard despite some drawbacks. Many question the validity of venous blood gas for a routine clinical practice application. Arterial and venous pH are clinically interchangeable with a consistently narrow mean difference (bias: 0.03) and ...
