The term acidosis was first mentioned in the medical literature in 1898 in connection with the description of diabetic ketoacidosis. Alkalosis was first used in human medicine in 1922 by the English physiologist J. S. Haldane; it had been used in veterinary medicine somewhat earlier. In 1870, the Norwegians C. M....

When collecting blood for blood gas analysis, it is important to remove air bubbles from syringes to avoid erroneous results, especially for pO₂, with a number of factors affecting the potential magnitude of the interference to pO₂ by air bubbles.  In this study, we calculate the expected theoretical changes in pO₂...

A new parameter called critical reference change value (CrRCV) to be applied for the interpretation of serial measurements of cardiac troponin I (cTnI) is introduced. To illustrate the practical utility of CrRCV a set of clinical examples based on two consecutive cTnI results are presented. Thus three cTnI changes...

Emergency departments (ED) are challenged by increasing patient visits, overcrowding and prolonged length of stay (LOS). The cause of these problems is multifactorial. Delays in the laboratory are often perceived as contributing to delays in care and increased LOS. Implementation of selected point-of-care tests in...

Abdominal aortic aneurysms (AAAs) are currently identified by incidental imaging or ultrasound screening. The potential diagnostic and prognostic value of D-dimer for AAA was assessed in this study. 1260 men from a population-based ultrasound screening study were included, of which 299 had small AAAs monitored by...

Patients with sepsis, severe sepsis and/or septic shock are at increased risk of death and organ dysfunction.  While morbidity and mortality of patients with severe traumatic injury, acute myocardial infarction or stroke have been significantly reduced during recent years by the implementation of well-coordinated...

Point-of-care testing sites continue to increase in number due to the availability of easy-to-use devices that make it possible to provide test results very quickly relative to the central laboratory services. There is, however, mixed review regarding the accuracy and reliability of POCT results for patient care. It...

The following is a copy of an article from Nursing 2007, Fall 2007 Volume 37 Number 8 - Supplement: ED Insider, Pages 14 - 16 The D-dimer level is a measure of clot formation and lysis that results from the degradation of cross-linked fibrin. Widely used as an indicator for the presence of disseminated intravascular ...

Over the years, as clinicians have learned how to utilize it, permissive hypercapnia has been finding a place in healthcare. However, it is important to bear in mind that numbers do not tell the entire story. It is imperative to understand the entire clinical picture before you act. For example, an acidic pH of 7.21...
