Lactate and lactic acidosis
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 ...

Ionized calcium
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...

Pseudohyponatremia
Measurement of plasma/serum sodium concentration is one
of the most frequently requested blood tests in clinical practice.
Although usually performed in the laboratory, the test is also
available at the point of care using technology incorporated into
blood gas and other point-of-care analyzers.
In health, sodium...

Lungs, kidneys and acid-base
The maintenance of normal blood pH depends crucially on synergy
of action between lungs and kidneys, so that students of acid-base
physiology must become familiar with the interrelatedness of kidney
and lung function in both health and disease.
This interrelatedness
is the central theme of a recently published review ...

Reporting calculated GFR from serum creatinine
The National Kidney Disease Education Program (NKDEP)
Laboratory Working Group reviewed problems related to serum
creatinine measurement for estimating glomerular filtration rate
(GFR) and prepared recommendations to standardize and improve
creatinine measurement.
The NKDEP recommends using the estimating equation...

Red-cell transfusion – risks and benefits - part 2 of 2
This is the second of two articles about the risks and benefits of red-cell transfusion directed at healthcare professionals without any particular transfusion expertise.
The focus of the first article was the risks and the extensive measures taken to minimize those risks.
For this second article, attention turns to...

Understanding the principles behind blood gas sensor technology
Today’s blood gas sensors are the result of many
years of gradual improvements and optimizations. The operating
principles behind sensor technology have largely remained
unchanged, even though the size of analyzers and thus of
sensors has decreased remarkably.
However, miniaturization has
created a new challenge: to ...

Hematocrit - a review of different analytical methods
To assess anemia and reduced oxygen-carrying
capacity, a measurement of hematocrit and/or hemoglobin is
performed. Whether hemoglobin or hematocrit is preferred
depends on different needs and is often determined by
tradition.
Both hematocrit and hemoglobin are important
hematology parameters for diagnosing...

Diabetic ketoacidosis
Disturbance of the mechanisms which maintain normal
blood pH is a defining feature of diabetic ketoacidosis (DKA),
an acute and life-threatening complication of the chronic
metabolic disease, diabetes.
For this reason diagnosis and
monitoring of DKA invariably include measurement of arterial
blood gases. This...
