The University College London Hospitals (UCLH) is one of the largest NHS trusts in England. The Elizabeth Garrett Anderson and Obstetric Hospital houses the Trust's gynecology, obstetric and neonatal services. At the neonatal unit, blood gas monitoring has historically been done by a combination of blood gas...

Venous blood is an acceptable alternative to arterial blood for estimation of bicarbonate by blood gas analysis, according to the results of a recently published Australian study. Over a six-month study period, clinicians at the Emergency Department of Western Hospital in Melbourne simultaneously sampled venous and...

In a recent editorial, UK blood-transfusion experts argue that the spiraling cost of maintaining and improving the safety of the blood supply is becoming increasingly less cost effective.  Over the past ten years the cost of the UK blood supply doubled in real terms from GBP 250 to GBP 500 million.  Most of this...

Disturbance of normal acid-base balance is a defining feature of diabetic ketoacidosis (DKA), the acute and potentially life-threatening complication of diabetes that results from severe insulin deficiency. The cause of the acidosis in such cases is abnormal accumulation in blood of the two ketoacids, acetoacetate and ...

Mechanical ventilation is normally adjusted so that pCO2 is maintained within normal limits (35-45 mmHg). However, the intensity of ventilation required to sustain a normal pCO2 can cause mechanical damage to the lungs of patients with acute respiratory distress syndrome (ARDS).  One of the strategies used to minimize ...

Preterm, very-low-birth-weight babies require intensive laboratory testing, including frequent blood gas analysis, during the first few weeks of life. It has been estimated that the weekly blood loss associated with phlebotomy for blood testing can amount to as much as 30 % of the total blood volume of these tiny,...

Can blood gas results be used to predict respiratory failure in victims of severe trauma? Many such patients present with metabolic acidosis, invariably the result of increased lactic acid production due to hemorrhagic shock. The normal physiological (compensatory) response to preserve a normal pH in those with...

A raised serum bilirubin (hyperbilirubinemia) and consequent jaundice is a common feature during the neonatal period; more than half of all newborns develop mild jaundice – with serum bilirubin rarely exceeding 150 µmol/L – during the first week or two of life. This transitory phenomenon usually resolves spontaneously ...

Simple data-mining algorithms can be applied to point-of-care testing (POCT) data to document compliance of quality control, operator training and to identify potential preanalytical errors. Data can be manipulated to automate manual review and other laborious processes for identifying data trends, verifying...

What does it take to ensure an effective competency program? Acutecaretesting.org asked three point-of-care coordinators (POCC) with solid programs what makes their competencies work. Their input resulted in a list of 12 key recommendations.
