Venous blood is an acceptable alternative to arterial blood for estimation of bicarbonate by blood gas analysis, according to the results of a recently published Australian study. Over a six-month study period, clinicians at the Emergency Department of Western Hospital in Melbourne simultaneously sampled venous and...

Oxygen is one of the most widely used drugs in medicine, and especially so in the newborn period. In many cases, oxygen supplementation is needed and is life-giving, but we are also aware of its toxic effects. In spite of this, we still do not know exactly what is the correct way to administer this drug. It is a...

Neonatology, perhaps more than any other field in medicine, has undergone dramatic improvements in care over the last several decades. One of the main areas of advancement is the ability to mechanically ventilate premature infants with a variety of neonatal lung conditions. As survival of premature infants has...

The significance of good practice during the pretesting phase of clinical laboratory investigation cannot be overemphasized. The production of high-quality, accurate results, which are clinically useful, depends as much on practice before the patient’s sample reaches the laboratory as it does on the analytical phase...

Today’s blood gas sensors are the result of many years of gradual improvements and optimizations. The operating principles behind sensor technology have largely remained unchanged, even though the size of analyzers and thus of sensors has decreased remarkably.  However, miniaturization has created a new challenge: to ...

Disturbance of the mechanisms which maintain normal blood pH is a defining feature of diabetic ketoacidosis (DKA), an acute and life-threatening complication of the chronic metabolic disease, diabetes.  For this reason diagnosis and monitoring of DKA invariably include measurement of arterial blood gases. This...

50-75 % of all newborns develop jaundice during their first week of life [1,2,3]. The decision behind which treatment is necessary and when it should be initiated is based upon a measurement of the concentration of total bilirubin (ctBil) in serum, plasma or whole blood.  It is therefore obvious that it is important...

Blood gas analysis at the point of care plays an important role during and after an open-heart surgery. acutecaretesting.org recently talked to Prof. Knut Kleesiek, MD, Director of the Institute for Laboratory and Transfusion Medicine of the Heart and Diabetes Center North Rhine-Westphalia in Germany, to find out more ...

Oxygen saturation can be obtained from many different types of devices. This range of choices causes some confusion as to definitions of measured variables and their clinical interpretation. This article gives some historical background and describes the two different ways saturation can be obtained from a blood gas ...

Arterial blood gas analysis is a test most frequently performed on critically ill patients in the emergency room, recovery room and intensive care unit by nursing staff. One of the main purposes of the test is assessment of acid-base status, which is often disturbed during critical illness. This article is intended...
