Question: 1 / 400

Which of the following is the value of test load resistance used by most defibrillator testers to simulate external patient impedance?

50 Ohms

The value of test load resistance used by most defibrillator testers to simulate external patient impedance is commonly set at 50 Ohms. This is primarily for consistency and reliability in testing the performance of defibrillators. In clinical settings, the human body has an impedance that can vary, but it's standard to use 50 Ohms to provide a realistic simulation of the electrical resistance encountered during defibrillation.

The choice of 50 Ohms reflects practical considerations in ensuring that the defibrillator can deliver the appropriate energy levels as would be required in real-world situations. By using this standard resistance, technicians can verify that the defibrillator functions correctly and delivers the intended shock energy effectively, as it mimics the conditions present when treating a patient.
