The CU-SM1 is intended for cardiac rescue simulations during trainings for cardiac emergency responders.

The CU-SM1 is not intended for the precise and accurate measurements of defibrillator outputs. The measurement accuracy of the device is not guaranteed when used to measure shocks with energies less than 50 Joules. For shocks with energies between 50 and 200 Joules, the indicated measurement is within 10% of the true value.

The maximum voltage and energy that the device can handle are 2000V and 200 Joules, respectively.

Even though the shock energy and leading edge voltage measurements are not guaranteed for defibrillation shocks with energies below 50 Joules, the device may still be used in rescue simulations where the delivered shock energy is less than 50 Joules. In this case, the simulated ECG output of the simulator is still useful to the defibrillator. The delivered shock energy measurement, however, has to be discarded.

The connector cable that is included with the device is specifically designed for the family of defibrillators from CU Medical Systems, Inc. To use the CU-SM1 with defibrillators from other manufacturers, ECG cables fitted with banana connectors will have to be provided by the user.

The CU-SM1 can generate Normal Sinus Rhythm, Ventricular Tachycardia, Supraventricular Tachycardia, Ventricular Fibrillation, fine Ventricular Fibrillation, and Asystole ECG signals. The signal output of the device can be fed to the defibrillators manufactured by CU Medical Systems, Inc. to simulate a patient. This is useful during trainings on defibrillator use and testing of defibrillators.

The CU-SM1 can be used to measure the leading edge voltage and the energy output of any defibrillator.
