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....

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...

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...

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 ...

Optimizing all the steps in the testing cycle is as crucial to the success of point-of-care testing (POCT) as the measurement process itself. The complete POCT process or testing cycle is a complex series of events that involve many parties in any organization.  Consultation with all the people concerned is vital and ...

Point-of-care testing (POCT) is one of the most rapidly growing areas within laboratory medicine. The need for POCT has developed because in many cases the central laboratory has been unable to meet the expectations of clinical users, particularly with respect to turnaround time. It is widely recognized that...

Arterial blood gas analysis with the measurement of the partial pressure of carbon dioxide in arterial blood may be performed in the Pediatric ICU to evaluate the efficacy of ventilation or evaluate acid-base status. Although the direct measurement of PaCO₂ remains the gold standard, it provides only a single...

Apgar scores and umbilical artery pH have traditionally been used as objective measures of neonatal asphyxia. According to the literature, the practice of cord gas analysis varies greatly both between and within countries - whether analysis is performed, whether it is routine at all births and why it is performed...

Numerous method comparison studies of blood gas analyzer methods have been published in the literature; unfortunately, several studies show flaws in one or several aspects of experimental design, execution, statistical analysis or interpretation of results. The most common flaw seems to be an inability to separate...

The understanding and management of ventilation-perfusion (V/Q) relationships represents a cornerstone of intensive care unit (ICU) patient management.  The physiologic shunt calculation can reliably reflect the degree of gas exchange attributable to intrapulmonary disease or intracardiac shunting regardless of other ...
