Oxygen saturation – better measured than calculated
Ensuring adequate oxygen delivery to tissues is a prime objective of acute/critical medical care. There is no routinely available method for directly monitoring tissue oxygenation; instead clinicians must depend on available indirect measures.
Although not the only factor to be considered, measurement of the amount of ...

Oxygen therapy
Ensuring that tissues are adequately oxygenated, with the help of supplemental oxygen where necessary, is a prime objective of critical/acute medical care. By measurement of the amount of oxygen dissolved in blood (pO2(a)) and that bound to hemoglobin (sO2(a)), arterial blood gas analysis provides the most accurate...

The value and limitations of pulse oximetry
Whilst arterial blood gas analysis is the gold standard method for determination of arterial oxygen saturation (sO2(a)), pulse oximetry provides an alternative, more convenient method that does not depend on sampling arterial blood.
Because of its ease of operation and ability to monitor oxygen saturation in real...

Drug-related acid-base disturbance – a review article
Each issue of the journal Emergency Clinics of North America is devoted to the review of a single topic of relevance to emergency medical care. The topic for the February 2014 issue was clinical toxicology and one of the 11 review articles in this issue, written by an emergency care doctor with specialist interest in...

Unraveling metabolic alkalosis: a complex case history
Metabolic alkalosis, a disturbance of acid-base homeostasis, with many possible causes, is characterized by a primary increase in blood pH and bicarbonate (HCO3). Hypoventilation is the compensatory respiratory response to metabolic alkalosis that results in increased pCO2.
The often complex nature of the etiology of...

Venous versus arterial blood for blood gas analysis – revisited
Arterial blood is the “gold standard” sample for blood gas analysis. Compared with venous blood sampling, arterial blood sampling is technically more difficult as well as being more painful and hazardous to the patient. These are among the considerations that drive the continuing research interest in establishing...

Metformin-associated lactic acidosis – does severity determine survival?
Metformin is a widely prescribed oral antihyperglycemic drug for the long-term treatment of type 2 diabetes. It is considered a first-line drug treatment for those diabetic patients whose blood glucose remains uncontrolled by dietary and other lifestyle interventions. In addition to this established use, metformin has ...

Marked discrepancy in bicarbonate values explained – a case history
Plasma bicarbonate concentration (HCO3-), an essential parameter for the assessment of patient acid-base status, is routinely generated during blood gas analysis by calculation from measured pH and pCO2. It is also directly measured by chemical analyzers in clinical laboratories that offer bicarbonate as one component ...

Point-of-care athletes testing, a new approach to sport performance evaluation in high-level athletes
In high-level athletes preparation, using point-of-care testing (POCT) in sports-specific environments, we tried to define and control the levels of exercise intensities (“energy training zones”), to quantify metabolic functionality (sports-specific energy sources, baseline conditions, functional costs of exercise in...

Point-of-care blood gas testing decreases ventilator time of the post isolated coronary artery bypass patient
Fast, accurate blood gas testing is a critical component to managing the post isolated coronary artery bypass (ISO-CAB) patient in the hospital intensive care unit/coronary care Unit (ICU/CCU).
Post ISO-CAB patients are admitted to the ICU/CCU after surgery mechanically ventilated. Evidence-based medicine supports...
