Permissive Hypercapnia-Continuous Monitoring
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...

Understanding the principles behind blood gas sensor technology
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 ...

Jaundice in the newborn infant
About half of all newborn infants born at term develop
jaundice during their first days of life, and the lower the
gestational age the more frequent the jaundice is. Newborns
develop hyperbilirubinemia because of a large bilirubin
production, low hepatic excretion and enterohepatic
recirculation. At birth the newborn ...

Permissive hypercapnea: Protecting the infant lung
Almost as soon as healthcare providers began ventilating neonates with respiratory distress syndrome, the problem of chronic lung disease began. How to manage these children in a way to promote lung growth and disease-free survival has been the question for those involved in the care of these infants since that time....

Overcoming the limitations of barcode technology
The introduction of armband barcode scanning
capabilities to point-of-care glucose testing devices has been
shown to greatly reduce patient identification errors. Barcodes
may be scanned to identify operators, patient identification
and reagents. Barcode scanning, however, does not eliminate all
errors, and in some...

Biological variation - what’s it all about?
Biochemical and hematological analyses are done in laboratories, clinics, general practices and in point-of-care settings such as ITU. Generally, numerical test results are generated.
Test results vary in individuals over time due to preanalytical variation, analytical imprecision and biological variation. The...

Quality assurance of the preanalytical phase - complying with ISO 15189:2003
A specimen for clinical laboratory testing must be properly collected from the correct patient at the correct time with proper patient preparation, and the right test must be performed for answering the right question.
Quality in the preanalytical phase of laboratory activity can be assured by implementing a quality...

Hematocrit - a review of different analytical methods
To assess anemia and reduced oxygen-carrying
capacity, a measurement of hematocrit and/or hemoglobin is
performed. Whether hemoglobin or hematocrit is preferred
depends on different needs and is often determined by
tradition.
Both hematocrit and hemoglobin are important
hematology parameters for diagnosing...

The heart of the matter
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 ...

Useful tips to avoid preanalytical errors in blood gas testing: neonatal total bilirubin
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...
