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...

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...

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 ...

Cord blood ph measurement at birth, using relatively simple and non-invasive methods, provides obstetricians and perinatologists with an objective and sensitive measure for the condition of the infant during the final stage of birth.  As long as certain criteria are observed, the reported values are reliable. Routine ...

Every POCT program today struggles with providing a solid program that is error free.  Each program must be designed to fit the needs of the organization, so having the right people in key positions is important. Additionally, training and competency programs are necessary so that each POCT operator understands the...
