In the majority of U.S. healthcare institutions, patient wristbands do not contain barcodes, creating a situation where patient data is manually typed into a database or point-of-care device, leaving plenty of room for error.  In light of error statistics issued by the United Kingdom’s National Patient Safety Agency...

Ever since the landmark document “To err is human” [1] was released, patient safety has been the paramount objective in US hospitals. “Patient safety” became the catch phrase and focus for all activities; a trend that was rapidly taken up by the rest of the world’s hospitals. Suddenly a new catch phrase – “lean” – ...

Mock inspections are a great way to prepare for real-life inspections from regulatory agencies such as CAP and JCAHO. But where do you start? And most importantly, what should you look for? Lou Ann Wyer, Clinical Specialist, POCT at the Virginia-based Sentara Laboratory Services and Theresa Kulik, Point-of-care...

Hypoxia and hypoxemia describe states of oxygen deficiency: hypoxia is deficiency in oxygenation at tissue or cellular level whilst hypoxemia is a suboptimal normal partial pressure of oxygen. Hypoxia and hypoxemia are interrelated, as untreated hypoxemia will ultimately result in hypoxia.  It should also be noted...

Blood gas analysis of umbilical cord blood provides the means for establishing the acid-base status of babies at the time of birth. If there is to be any delay in sampling, the portion of cord from which the sample is to be taken should be double-clamped and thereby isolated from the placenta.  Previous studies have...

Hemorrhage, due to a reduction in the coaguability of blood, is a common cause of morbidity and mortality among trauma victims and the critically ill in general. Reduced blood pH (acidosis) is also common in these patient groups. Previous studies have shown that acidosis is an independent risk factor for development...

Modern blood gas analyzers have incorporated technology that allows spectrophotometric measurement of bilirubin concentration on the same whole-blood sample that is used to measure blood gas parameters. A recent French multicenter study confirms the reliability of this technique for measuring bilirubin during the...

In 2001 a landmark study demonstrated that normalization of blood glucose significantly reduces mortality and morbidity among intensive care patients. Now 5 years on, strict control of blood glucose concentration with insulin therapy is accepted as an imperative of optimal intensive care in many hospitals around the...

Measurements of pH, pCO₂ and pO₂ of arterial blood during blood gas analysis are all made at normal body temperature, 37 °C. The sample is warmed to that temperature prior to analysis. Blood gas analyzers provide the option for these primary measurements to be automatically "corrected" to the patient’s actual body...
