G-100 Blood Gas Analyzer-Performance verification
1. Accuracy verification
Verify the accuracy data of the blood gas analyzer using a certified third-party quality control solution at a known concentration. Under normal conditions, the analyzer is calibrated first according to the test procedure, and then the quality control liquid is continuously measured for 5 times, respectively to obtain the mean value of each analytical element in the quality control liquid, and calculate the deviation between the determination value of each analytical element and the reference value of the quality control liquid.
| Item | QC liquid reference value | Instrument measured mean value | Deviation |
| pCO2 (mmHg) | 40 | 40.5 | +0.5 |
| pO2 (mmHg) | 100 | 99.4 | -0.6 |
| Na+ (mmol/L) | 140.0 | 141.2 | +1.2 |
| K+ (mmol/L) | 3.90 | 3.87 | -0.03 |
| Ca++ (mmol/L) | 1.10 | 1.12 | +0.02 |
| NH4+ (mmol/L) | 28.0 | 28.2 | +0.2 |
2. Accuracy verification
Precision of standard liquid test instrument from Sieman Technology. Under normal conditions, the analyzer was calibrated first according to the conventional test procedure, and then the standard liquid was measured for 10 consecutive times, and the mean value, standard deviation and CV of each analytical element were obtained respectively.
| Item | Mean value | SD | CV |
| pCO2 (mmHg) | 35.2 | 0.37 | 1.05% |
| pO2 (mmHg) | 149.3 | 0.72 | 0.48% |
| Na+ (mmol/L) | 151.6 | 0.48 | 0.32% |
| K+ (mmol/L) | 4.06 | 0.03 | 0.65% |
| Ca++ (mmol/L) | 1.26 | 0.01 | 0.98% |
| NH4+ (mmol/L) | 5.60 | 0.03 | 0.64% |
