The intraoperative monitoring of the partial pressure of carbon dioxide in arterial blood (pCO₂) is used to assess the adequacy of ventilation and guide clinical interventions.  Although end-tidal CO₂ monitoring remains the most frequently used non-invasive technology in the intraoperative setting to provide a...

Neonates are subject to more preanalytical influences than any other population group. Many of these are related to the maturity of the infant and its adaptation to extra-uterine life. The necessary need for capillary blood collection and processing of small quantities of blood introduce additional preanalytical...

Whether performed by one "traditional" or several "point-of-care" devices, all Multi-Profile Blood Gas (MPBG) results must be accurate and precise if they are to be effective in managing critically ill patients. Optimal analytical quality control of multi-profile blood gas analysis requires a good quality assurance...

The concept of “metrological traceability” is important when establishing comparable clinical decision limits for a measured analyte at different hospitals within one country and in different countries.  This can only be achieved if all instrument manufacturers establish the performance characteristics of their...

What quality is being controlled in laboratories today?  The definition of a quality requirement for each laboratory test is the starting point of quantitative quality management. Different types of requirements may be used as long as there are appropriate quality-planning models for translating those requirements...

While analytical quality standards seem well established, there has been a paucity in the development of such standards for the preanalytical phase.  Technical recommendations regarding sampling, transport, and identification have been developed in national (NCCLS, DIN) and international (IFCC, ISO) consensus...

60 % of all neonates develop jaundice during their first week of life and thereby run a risk of getting hyperbilirubinemia.  Although different approaches for establishing treatment criteria have been suggested, treatment of neonatal hyperbilirubinemia is usually still based on the measurement of total bilirubin...

Two months of acclimatization to high altitude leads to an adaptation of the aerobic capacity of the myocardium, characterized by an increased ability to extract O₂ from the coronary vascular bed. An increased mitochondrial volume and activity of oxidative enzymes or improved diffusion conditions could be involved.

How relevant is transcutaneous measurements in the detection of critical limb ischemia?  Acutecaretesting.org has asked a group of respected researchers and clinicians in the US and Europe to describe how they use transcutaneous measurements in their daily work.

Point-of-care testing (POCT) is a delivery option for performing laboratory testing closer to the patient. Due to increasing healthcare pressures for faster turnaround of laboratory results and the development of a broader menu of testing devices, POCT is growing in popularity. Devices today are more portable,...
