The FingerSim from BC Biomedical, St Charles, Mo, allows users to test equipment the way it was designed to be used. By placing a FingerSim in a finger cuff and squeezing the color-coded flat end, a pulsatile movement of the solution is produced, which is detected as a pulse by the oximeter system.

The FingerSim system provides a swift and inexpensive means of assessing the function of the entire pulse oximeter system, including the sensor. All kits include a set of three FingerSims, each containing a fluid with precisely controlled light-absorption characteristics sandwiched between two glass slides. It can be used as a stand-alone testing system or in conjunction with one of the company’s pulse generators, allowing users to obtain a calibrated pulse rate along with the saturation level.
