Step by step Instructions for monitoring and gating

Click the PC-sam icon on the desktop > select "Start Monitor with Selected Setup" to
view the main monitor display screen. The "selected setup" should be "factory defaults"
which includes ECG, respiration from the pillow sensor, temperature from the thermister
probe and ECG gating. Refer to Chapter 3 to alter the monitor configuration.
Attach ECG electrodes, a pneumatic pillow respiration sensor and the thermister
temperature probe to the animal following instructions in Chapter 4.
ECG and respiration waveforms along with temperature measurements should appear
similar to those shown below. If your ECG waveform has negative rather than positive
peaks, switch the electrodes at the red and white connectors on the ERT Module.
Note the presence of small red bars above the peaks of the ECG waveform which
indicate R-wave detection. Longer red bars appear above the respiration waveform
which coincide with the animal's expiration. White dots appear at the same time in both
the Cardio and Resp Sweep displays whenever a gate is sent from the ERT
Control/Gating Module to the MR scanner.
The heart and respiration rates are displayed to the right of the waveforms measured in
beats or breaths per minute. The period displayed below each rate is the time interval
