What Researchers Did
This study evaluated the accuracy of two bedside blood glucose meters, Precision PCx and SureStepPro, using human blood samples under varying oxygen pressures, including hyperbaric conditions.
What They Found
The SureStepPro meter's readings were largely unaffected by high oxygen pressure, showing only a 1.3 +/- 6.5 mg/dl difference at 1200 mmHg P(O2) compared to 60 mmHg. In contrast, the Precision PCx meter exhibited a significant bias of 47.9 mg/dl and imprecision of 35.1 mg/dl at 1200 mmHg P(O2), compared to the SureStepPro.
Canadian Relevance
This study has no direct Canadian connection as it was not conducted in Canada nor involved Canadian participants or institutions.
Study Limitations
A limitation of this study is that it evaluated only two specific blood glucose meters using in-vitro blood samples, which may not fully reflect real-world clinical performance in patients.
