Correct Blood Sampling for Blood Gas Analysis

Arterialised blood gas sampling in the critically ill: Correct tools for the job?

Sampling from blood has been performed for over 200 years. However clinically useful arterial blood gas sampling became a reality after the development of robust methods for measuring oxygen tension from humans in the 1940s. Thus the development of the Clark electrode and subsequent safe tools for sampling plasma, heralded an era of blood sampling, and analysis from which we have not looked bac...

Accuracy of intrapartum fetal blood gas analysis by scalp sampling

Fetal blood gas analysis (FBGA) using scalp blood is commonly used to identify serious fetal distress. However, there is a lack of data regarding its accuracy and reliability. The aim of this study was to determine the positive predictive value (PPV) and negative predictive value (NPV) of FBGA for predicting postpartum acidosis in case of nonreassuring fetal heart rate tracings (NRFHRT). To thi...

Arterial blood gas analysis.

With increasing use of arterial blood gas analysis in various ward and other hospital settings to aid medical diagnosis and management, nurses who can interpret results are often able to initiate earlier interventions and understand the reasons for medical interventions. This article enables nurses to interpret such results.

Blood gas analysis is a time-consuming procedure, taking up to 30 minutes from obtaining a blood sample from the patient to receiving the results. The process can involve as many as three health care professionals: the doctor, nurse and a member of the pathology department. The result is that it is difficult to provide continual monitoring of blood gas levels on patients with acute respiratory ...
