Modern analytical devices for testing biological fluids, such as blood, have now developed a sophistication that ensures the quality of the analytical result is capable of matching that achieved in the central laboratory.    Complementary developments are focused on reducing operator-related and connectivity-related...

The integrity and function of all cells depend on an adequate supply of oxygen. Severe acute illness is frequently associated with inadequate tissue perfusion and/or reduced amount of oxygen in blood (hypoxemia) leading to tissue hypoxia.  If not reversed, tissue hypoxia can rapidly progress to multiorgan failure and ...

Part 2: Red flags The transition from fetus to newborn is a process of rapid physiological adaptation that is sometimes delayed by complications. Most newborns complete the process of transition with little or no delay.  These infants may demonstrate normal transitional findings, including tachypnea and tachycardia, ...

In 2005, acutecaretesting.org interviewed Dr Michael Astion, an active spokesperson for patient safety and reduction of lab errors, on the main issues surrounding the topic. Since then, a lot has changed… or has it? In a follow-up interview with Astion, acutecaretesting.org gauges the status of patient safety year...

Part 1: The physiology of transition The transition from fetus to neonate is a critical time of physiological adaptation. While the majority of term infants complete this process in a smooth and organized fashion, some infants experience a delay in transition or exhibit symptoms of underlying disease. Careful...

This essay is a follow-up to the 2006 series expressing concern that there is a widespread gap between QC theory and QC practice. Now we are giving you, the reader, the opportunity to rate your own QC practice and to help prove or disprove that gap.  If the QC theories generally recommended by recognized QC experts ...

Homeostatic mechanisms ensure that in health the extracellular fluid (ECF) concentration of electrolytes, including calcium, is maintained within well-defined limits. Abnormality in ECF calcium concentration can have profound adverse effects.  The most common means of assessing calcium status is to measure total...

In most hospitals, the amount of nursing time spent on actual patient care is only 33 %, while problem solving consumes 40 % of their time. That’s the bad news. The good news is that inverting this ratio may be easier than you think.  According to Dr John Kenagy and David Sundahl of the US-based Kenagy & Associates,...

Blood gas analysis is a complex field that has a direct impact on patient care in a critical care environment. Healthcare professionals consistently emphasize high-quality results in order to properly treat patients, and recognize the need and usefulness of quality standards.  Using a path-of-workflow analysis as part ...
