Calculation-based approaches to determining oxygen saturation, as used in some point-of-care tests, increasingly deviate from values measured directly by CO-oximetry as the partial pressure of oxygen in the blood decreases. Oxygen saturation should be measured by CO-oximetry when inaccuracies in calculations may...

Is it a good idea to rely on vendors to help develop training materials for point-of-care testing staff? According to the lab group responsible for point-of-care (POC) testing at the Malmö University Hospital in Sweden, vendor cooperation can help you achieve a better result, faster. However, the better prepared you ...

Examination of peripheral pulses and peripheral blood pressures are commonly used methods for investigation of macrocirculation. However, falsely elevated peripheral blood pressures may complicate the accurate prediction of ulcer healing in diabetic patients.  Because tcpO₂ also measures the nutritive skin capillary...
