Dynatech/Nevada Patient Simulator

Modification

The factory configuration of the Dynatech/Nevada model 214A, 215A, and 217A Patient

Simulators is incompatible with the Propaq Encore monitors with IBP channels when both

the ECG and invasive pressure simulator channels are simultaneously connected to the

monitor. Erroneous readings result. The patient simulator must be modified as described

here before you can use both simulator channels with the Propaq Encore monitors with

IBP. If only one simulator channel is used, the modification is unnecessary.

Modify the patient simulator's invasive pressure cable as shown in the figure below.

Remove jumpers W1 and W2 from the patient simulator's Top PCB.

Incompatibilities with other simulators may also cause erroneous readings and/or missing

ECG. Check Propaq Encore readings with the simulator against a known source before

using the simulator for calibration.

Note

Without this modification, the monitor will select a single waveform or parameter

for display.
