The single-mode button featured on the OxSim pulse oximeter tester from Pronk Technologies, Sun Valley, Calif, automatically detects most major brands of oximeters. The ruggedness of the palm-sized simulator has been established during testing—65 drops from a height of 3.5 feet onto a hard surface. It furnishes 8 hours of continuous simulation on one AA battery. The unit provides four saturation values, three heart rates, and two perfusion levels, which enable users to test the accuracy and sensitivity of an oximeter’s sensor and electronics. Combining OxSim with SimCube and SimSlim provides complete and portable vital signs testing. The product includes a 3-year warranty.
The FingerSim pulse oximeter test system from BC Biomedical, St Louis, allows health care professionals to evaluate pulse oximeter and sensor function at three simulated, light-absorption conditions. As red and infrared light pass through the finger, oxygenated hemoglobin in the subject’s finger absorbs some of the light and determines the SPO2 level. FingerSim mimics the human finger and is designed to work with most manufacturers’ finger probes. The unit can be used in a stand-alone mode or with any of the company’s high-end simulators to synchronize SPO2 with ECG simulation. The system provides a cost-effective, portable way to test SPO2.
