Correlation of venous blood gas and pulse oximetry with arterial blood gas in the undifferentiated critically ill patient. J Intensive Care Med. 2018;33(3):176-181. Touger, M, Gallagher, EJ, Tyrell, J. Relationship between venous and arterial carboxyhemoglobin levels in patients with suspected carbon monoxide poisoning.


PURPOSE: To determine whether the use of venous blood gases can be a suitable alternative to arterial sampling to evaluate acid-base status. METHODS: The database of the clinical laboratory in a large academic hospital was searched for records of venous blood gas analysis and an arterial sample taken within ten minutes from the same patient.


Keywords: Arterial blood gas, Blood gas analysis, Venous blood, Venous blood gas Introduction ABG is an effective method of estimating PO 2 , PCO 2 , bicarbonate and pH, usually for the purpose of assessing ventilation and/or acid-base status [ 1 ].


Venous blood gas: Blood gas results are taken on arterial blood only. If the technician did not get an arterial sample while attempting to get a blood gas, the results ... If the technician did not get an arterial sample while attempting to get a blood gas, the results ...


At the present time, arterial blood gas analysis is the gold standard for assessing the acid–base status, though there are reports on the agreement of base excess and lactate levels determined in arterial and venous blood. 39,40 However, the popularity of venous blood gas analysis is low and some studies have expressed reservations regarding ...


Background: Arterial blood gases (ABGs) are the gold standard to assess acid-base balance, ventilation and blood oxygenation. However, using venous blood gases (VBGs) could avoid the pain and complications associated to ABGs. No studies have assessed if VBGs are comparable to ABGs in reaching the same diagnosis of normal vs. abnormal pH, CO2, and HCO3-.


Background and objectives: Venous blood gas (VBG) analysis is a safer procedure than arterial blood gas (ABG) analysis and may be an alternative for determining acid-base status. The objective of this study was to examine the agreement between ABG and central VBG samples for all commonly used parameters in a medical intensive care unit (ICU) population.


Venous vs arterial blood gases in the assessment of patients presenting with an exacerbation of chronic obstructive pulmonary disease. The American Journal of Emergency Medicine, Vol. 30, Issue. 6, p. 896.


Thus, this strategy is unable to yield a universally applicable equation which can relate arterial and venous blood gas values. Similar variation is notable when evaluating the published literature regarding ABG vs. VBG comparison, explaining why these equations haven't gained clinical acceptance.


As a Respiratory Therapist, one of the skills you will be performing most is Arterial Blood Gas (ABG) sampling and analyses. The results of an ABG can serve as one of the most accurate ways to assess a patient’s clinical condition, and often times will be the deciding factor between whether a patient has to endure the trauma of intubation and mechanical ventilation, or, be managed less ...
