Biological quality control for exercise testing.

BACKGROUND A study was undertaken to evaluate the use of a biological quality control programme for a computer controlled, breath-by-breath exercise test system over a 2.5 year period. METHODS One healthy volunteer performed a regular progressive treadmill test with breath-by-breath measurements of oxygen uptake (VO(2)), carbon dioxide output (VCO(2)), ventilation (VE), and the ECG heart rate...

Biological quality control for cardiopulmonary exercise testing in multicenter clinical trials

BACKGROUND Precision and accuracy assurance in cardiopulmonary exercise testing (CPET) facilitates multicenter clinical trials by maximizing statistical power and minimizing participant risk. Current guidelines recommend quality control that is largely based on precision at individual testing centers (minimizing test-retest variability). The aim of this study was to establish a multicenter biol...

Production, formulation, quality control and primary biological studies of [18F]KF for skeletal PET scanning [Persian]

[18F]KF, considered as a reference standard for positron emission tomography of the skeletal system, was produced by the bombardment of enriched water ([18O]H2O>95%) with high energy protons in NRCAM cyclotron. After the extraction of fluoride from enriched water as KF, and passing it through microbial filter and fine adjustment of acidity and osmolality, it was converted into an injectab...

Proficiency testing for blood-gas quality control.

We have conducted a voluntary, community blood-gas proficiency testing program, with use of tonometered human blood, for 32 analyzers located in 16 laboratories. Instruments initially showed inaccuracies as large as -30.8 to +17.3% for po(2), and -14.0 to +42.9% for pco(2), but inaccuracy and imprecision decreased in most laboratories during the program. For a typical 15-week period, mean group...

Workrate and Cadence Control for Exercise Testing in FES Cycling

Lower-limb FES cycling for paraplegic and tetraplegic subjects has been previously described, with systems for both stationary ergometry and for mobile outdoor cycling being available. The potential therapeutic and medical benefits of FES cycling exercise have recently been surveyed [1]. A key finding is that regular FES cycling exercise leads to improved cardiopulmonary fitness, with a corresp...
