Den största förbättringspotentialen finns på områdena inten- sivvård nosocomial infections: stratified analysis of national preva- lence studies of infection associated with central venous and arterial cathe- ters. Lancet  Since venous blood gas is easy to sample from the peripheral veins or the central veins in patients with central venous catheters, it is a more comfortable and an easy procedure for some patients and the physicians. In many studies, a very good correlation has been shown between venous blood gas and the arterial blood gas. Venous blood gas (VBG) interpretation Arterial blood gases (ABGs) are commonly used for estimating the acid-base status, oxygenation and carbon dioxide concentration of unwell patients. However, arterial blood can be difficult to obtain due to weak pulses or patient movement.

Venous blood gas interpretation

Your doctor may run a blood gas analysis or arterial blood gas (ABG) test if you are showing the signs of an oxygen, carbon dioxide, or pH imbalance such as confusion or difficulty breathing. The mixed venous sample also captures the blood before it is re-oxygenated in the pulmonary capillary. Because pulmonary artery catheter use has declined dramatically, ScvO2 measurements obtained from internal jugular or subclavian catheters are often used and interpreted in the same manner. An ScvO2 refers to a central venous sample.

Freedom from bubbles in venous blood is usually considered to be enough signal to allow interpretation of a possible gas passage and presence of a PFO. of automated blood gas analysis, the innovative Rapidlab 1200 analyzer simply works.

In some situations analysis of venous blood can provide enough information to assist in clinical decisions. In general, the pH, CO 2 and HCO 3 ˉ values are similar in venous and arterial blood (Box 1). The main difference is the partial pressure of oxygen in venous blood is less than half that of arterial blood.
